(f) The Company may require periodic reviews of the Facility, maintenance records, available operating procedures and policies, and relay settings, and may request changes that it deems necessary to protect the Company’s System from damages resulting from the Seller’s parallel operation. If the Company exercises such right, the Company shall inform the Seller as soon as practicable, and in no event later than forty-five (45) Days after such review or inspection, of any problems it believes exist and any recommendations it has for correcting such problems.

(g) The Company’s inspection and acceptance of the Seller’s equipment and settings shall not be construed as endorsing the design thereof, nor as any warranty of the safety, durability or reliability of said equipment and settings, nor as a waiver of any of the Company’s rights. In no event shall any failure by the Company to exercise its rights under this Section 3.2A(6) constitute a waiver by the Company of, or otherwise release the Seller from, any other provision of this Agreement.

(h) The Seller and the Company shall cooperate with each other in good faith in agreeing upon design standards for any equipment or settings referred to in this Section 3.2A(6).

(i) Within a reasonable time after receipt of the Company’s comments referred to in this Section 3.2A(6) or notification by the Company of problems related to the Seller’s obligations under this Section 3.2A(6) but no later than ninety (90) Days after such notification (unless such condition is causing a safety hazard or damage to the Company’s electrical system or the Company’s customer’s facilities, in which event the correction must be promptly made by the Seller), the Seller shall implement the Company’s proposals. The Seller shall notify the Company when modifications have been completed. If the Seller does not implement

ARTICLE 3

changes the Company deems necessary for parallel operation or to protect the Company’s System from damages resulting from the parallel operation of the Seller’s Facility with the Company’s System, the Company may take action including disconnection.

(j) Notwithstanding the foregoing, the Seller shall utilize relay settings prescribed by the Company, which may be changed over time within the design capability of the equipment as the Company’s electrical system’s requirements change.

(7) Progress Reports

On the first Day of each month following the Execution Date and continuing until the Commercial Operation Date, the Seller shall provide the Company with monthly progress reports containing a reasonable level of detail on the status of efforts to meet each Milestone Date. If, during any month, the Seller has reasonable cause to believe that it will be unable to achieve any Milestone Date, it shall so inform the Company as soon as practicable, but no later than the next monthly progress report. At the Company’s request, the Seller shall provide an opportunity for the Company to meet with appropriate personnel of the Seller or its contractors to discuss and assess any such monthly progress report.

(8) Construction Sequencing

Construction of the Expansion Facility shall be completed without interference or reduction of the Existing Facility’s electrical output, with the exception of critical interconnections which cannot be made unless equipment must be first de-energized, depressurized, drained, cooled or otherwise made safe for construction activities to take place. Any such events will be carefully coordinated with the Company to ensure continuity of service to the Company’s customers.

B. Operation and Maintenance of Facility

(1) Standards

(a) The Seller shall operate the Facility in accordance with Good Engineering and Operating Practices. Subject to those standards, the Seller shall deliver to the Company the Net Electric Energy Output up to the Available Capacity of the Facility under Company Dispatch and shall use its best efforts to operate the Expansion Facility in a manner that maximizes the overall reliability of the Company’s System.

(b) The Facility shall not trip for a transient condition in the Company’s System less than thirty-six (36) cycles

ARTICLE 3

duration, or a resulting trip shall be considered a Unit Trip which shall count towards the number of allowable Unit Trips under Section 3.2D(5) (Unit Trips) and shall count against the Seller’s availability for both the Equivalent Availability Factor and Equivalent Forced Outage Rate. For example, an electrical fault and subsequent clearing of such a fault shall be considered one transient event.

(2) Functioning Protective Equipment

The Seller shall operate the Facility with all system protective equipment in service whenever each generator is connected to or is operated in parallel with the Company’s System, except for normal testing purposes in accordance with Good Engineering and Operating Practices. The Seller shall have qualified personnel test and calibrate all protective equipment at regular intervals not to exceed one (1) calendar year. A unit functional trip test shall be performed annually on the Expansion Facility in accordance with industry standards. Following a Major Equipment Overhaul, a functional trip test of the overhauled major equipment shall be performed and shall simulate abnormal trip conditions separately at each primary element that initiates a trip and shall demonstrate that the trip system produces the appropriate equipment response. In no event shall any trip test conducted pursuant to this Section 3.2B(2) constitute a Unit Trip. If at any time the Company has reason to doubt the integrity of the Facility’s protective equipment and reasonably suspects that such purported loss of integrity would jeopardize the reliability of the Company’s supply of electrical energy to its customers, the Seller shall be required to reasonably demonstrate to the Company’s satisfaction the correct calibration and operation of the equipment in question. The Seller shall ensure that Facility equipment critical to the continued operation and supply of power, including both auxiliary and primary generating equipment, shall not be tripped due to relay protection triggered solely by off-normal low system voltage or off-normal system frequency conditions (i.e.; protective 27 (undervoltage) and 81 O/U (frequency) relaying shall be set to alarm only). Facility equipment may trip for protection due to the effects of a system event, providing the design parameters meet the expected performance during over/under voltage and frequency as defined in Section 3.2C. The Company shall not be liable for any damage to the Seller’s equipment resulting from the failure of the Facility’s protective equipment.

(3) Personnel and System Safety

The Seller shall provide, at a location approved by the Company, a manual disconnect device which provides a visible break to electrically separate the Expansion Facility from the Company’s System. Such disconnect device shall be lockable in the

ARTICLE 3

OPEN position and accessible to the Company personnel at all times. Notwithstanding any other provision of this Agreement, if at any time the Company determines that the continued operation of the Expansion Facility (i) is likely to endanger the safety of persons and/or property, (ii) is likely to endanger the integrity of the Company’s System or (iii) is likely to have an adverse effect on the equipment of the Company’s customers, then in each case (i) through (iii), the Company shall have the right to disconnect the Expansion Facility from the Company’s System, giving as much advance notice to the Seller as is practicable under the given circumstances. If the Expansion Facility is separated from the Company’s System for any reason, under no circumstances shall the Seller reclose into the Company’s System without first obtaining specific approval to do so from the Company’s System Operator which approval shall be granted promptly upon the removal of the cause of the condition in sub-clauses (i) through (iii) above. The Expansion Facility shall remain disconnected until such time that the condition specified under (i), (ii) or (iii) above has been corrected, and the Company shall not be obligated to accept or pay for any energy which might otherwise have been received from the Expansion Facility during such period. If the Company disconnects the Expansion Facility from the Company’s System, it shall immediately notify the Seller by telephone or hotline and thereafter confirm in writing the reasons for the disconnection. The claim of occurrence of any event pursuant to this Section 3.2B(3) shall be subject to verification by the Seller. The Seller shall be paid the Capacity Charge regardless of the causes of disconnection. If it is determined that the Company did not have a valid reason for disconnecting the Expansion Facility, the duration of the period of separation will not be counted against EAF or EFOR or for the purpose of calculating any other performance standard.

(4) Operating and Maintenance Records

Logs shall be kept by the Seller for information on unit availability, including reasons for planned and Forced Outages, circuit breaker trip operations, relay operations, and notations of abnormal operating conditions and events. The Seller shall also maintain operational records including target indications, relay reports, and other recorded operational data such as MW, MVAr, and voltages. Information shall be kept for unit availability including reasons for planned outages and Forced Outages, circuit breaker trip operations, relay operations, including target initiation and other unusual events. The Company shall have the right to review logs and other operational records such as relay target indications, relay reports, and other recorded operational data. The Seller will provide the Company with logs and other relevant data through written reports upon Forced Outages, planned outages, forced and planned derations, or Unit Trips, within 10 Days of the event. This shall include the recorded data and available reports generated from data from

ARTICLE 3

monitoring and recording equipment necessary to diagnose cause for loss of power output from the Facility and report the cause, as required in Section 3.2A(6) (Facility Protection Equipment). Reports will include the date and time of the occurrence as well as the cause of the Unit Trip, deration, or Forced Outage. The Company shall have the right to request reasonable additional information if necessary to evaluate the incident. “Attachment M” is an example of a written report. In addition, Seller shall provide EAF, EFOR, and average Available Capacity calculations each month (with the average Available Capacity calculation calculated (1) on a monthly basis for the Facility, and (2) on an hourly basis during on-peak hours separately for the Existing Facility and the Expansion Facility) showing the underlying calculations and supporting data. The EAF, EFOR and Available Capacity calculations will be provided within three (3) Business Days of the end of the month being reported. The EAF and EFOR calculations will be provided within ten (10) Business Days of the end of the month being reported. The Company shall have the right to request reasonable additional information if necessary to further evaluate these calculations.

The Company may require periodic reviews of the Seller’s Facility, maintenance records, available operating procedures and policies, and relay settings, and the Seller shall implement changes the Company deems necessary for parallel operation or to protect the Company’s System from damages resulting from the parallel operation of the Seller’s Facility with the Company’s System.

(5) [Reserved].

(6) Major Outages

If the Seller believes that a major outage is required to prevent a Catastrophic Equipment Failure, the Seller shall notify the Company as soon as practicable and the Company shall promptly act, upon the Seller’s request, to approve such outage, which approval shall not be unreasonably withheld, delayed or conditioned. The determination as to whether or not the outage constitutes a Forced Outage or a maintenance outage will be made in accordance with the NERC GADS Reporting Instructions referenced by this Agreement.

In the event of a Forced Outage or deration, the Seller shall inform the Company of the following: cause of the forced deration or outage, plans to address cause of the forced deration or outage, and anticipated dates and values of capacity increases and restoration(s). The Seller shall maintain sufficient data recording and monitoring equipment to enable diagnosis and cause of equipment trips, Forced Outages, and derations.

ARTICLE 3

C. Delivery of Power to the Company

The Seller shall operate the Facility (both the Existing Facility and Expansion Facility) in the following manner to provide power to the Company in accordance with this Section 3.2C.

(1) Voltage/Reactive Power Requirements

Electricity generated by the Seller shall be delivered to the Company at the Point of Interconnection in the form of 3-phase, 60 Hertz alternating current at a nominal operating voltage of 69 kV. The actual operating voltage will be determined by the Company.

Reactive kVAr requirements will be from 0.90 leading to 0.85 lagging power factor delivered by the Seller to the Company.

The Facility generators must be capable of automatically adjusting reactive control to maintain the bus voltage to meet the target specified by the System Operator. The target will be specified remotely by the System Operator through the EMS. The generators should not normally operate on a fixed var or fixed power factor setting except during startup or shutdown or if agreed by the Company.

The Facility shall have under-voltage and over-voltage ride through capability. The Facility shall behave as follows during under-voltage disturbances and over-voltage disturbances (“V” is the voltage of any of the three phases at the Point of Interconnection):

V ³ 0.80 pu

The Facility remains connected to the Company’s System in continuous operation.

0.75 pu £ V < 0.80 pu

The Facility remains connected to the Company’s System and in continuous operation for a minimum of two (2) seconds per event (while “V” remains in this range). The duration of the

ARTICLE 3

event is measured from the point at which the voltage drops below 0.8 pu and ends when the voltage is at or above .80 pu.

0.00 pu £ V < 0.75 pu

The Facility remains connected to the Company’s System and in continuous operation for a minimum of 600 milliseconds (while “V” remains in this range); the duration of the event is measured from the point at which the voltage drops below 0.75 pu. and ends when the voltage is at or above .75 pu.

· Droop Characteristic

Expansion Facility and Existing Facility organic cycle units - Each unit speed-droop characteristic shall have a nominal setting of 4 percent (4%) with no intentional deadband. The Company shall have the right to specify a different setting within the capabilities of the units. Droop setting shall be for the Existing Facility organic cycle units (total 11 MW [net to HELCO] – 1.22 MW each turbine [net to HELCO]) of the existing units in the Existing Facility.

Existing Facility Steam Turbines - The existing steam turbines (18 MW, 1.8 MW on each of ten (10) turbines) of the Existing Facility will provide an emergency frequency response to high frequency rather than a droop response. The emergency ramp-down will be achieved through steam bypass for the existing ten (10) steam turbines. The automated ramp down for high frequency will be provided by a controller at the Existing Facility based on a settable threshold with settable time delays, a high frequency threshold, and an emergency high frequency threshold. The initial settings will be 60.5 Hz with a time delay of ten (10) seconds and 62 Hz with no time delay. When activated, the bypass will result in ramping at the fastest sustainable ramp rate, but in any case no less than two (2) MW per minute. With the bypass feature, the Existing Facility will reduce power output automatically in response to high frequency up to fifty percent (50%) of steam turbine power or about ten (10) MW. Return from the high-frequency ramp is to be initiated after coordination with the Company’s System Operator.

Remote dispatch shall be provided between the range of twenty-two (22) MW to the Available Capacity. Notwithstanding anything to the contrary, the minimum amount of Remote dispatch shall be the Available Capacity of the Expansion Facility. The allocation of energy among units shall be determined by the Seller’s control system. The response of the Facility to Company Dispatch signals shall be immediate and allow the Facility to achieve, at a minimum, a ramp rate of two (2) MW per minute. The dispatch request shall reflect net MW from the Facility at the Point of Interconnection. The implementation of the remote dispatch control by the Seller shall not result in overriding the Facility droop response. The Company and the Seller shall work together on a detailed interface design for the AGC control.

· The Facility may disable remote dispatch by the Company for abnormal Facility operations such as equipment malfunctions, breakdowns, etc. The disabling of remote dispatch control by the Seller shall be immediately indicated through a status provided to the Company through the Remote Terminal Unit (“RTU”) telemetry interface to the EMS.

ARTICLE 3

· Minimum Load Capability. The combined output of the Facility shall allow for a net minimum load capability under remote dispatch of twenty-two (22) MW. The output of the Facility may be less than the net minimum load capability of twenty-two (22) MW under remote dispatch by the System Operator to the extent that the Existing Facility is producing less than twenty-two (22) MW or by the System Operator under disturbances or other unusual operating conditions which could be mitigated or addressed by the reduction of the Facility in the judgment of the System Operator, such as, but not limited to: excess energy conditions due to abnormal operating conditions such as could be caused by unexpected loss of load, system over-frequency, transmission equipment overload or risk of transmission overloads due to contingencies, and high voltages in the vicinity of the interconnection.

· Ramp Rates. The available ramp rate for dispatch during normal (non-emergency) system conditions shall be two (2) MW per minute. When requested by the Company through its remote dispatch or by other means, under emergency conditions, the Seller shall use reasonable efforts to maximize such ramp rates to the extent the Facility is capable of doing so within manufacturer’s specifications and warranties. The Seller shall inform the Company of the maximum available ramp rate under remote control.

utilize its EMS and information on breaker position, the number of generating units on line, the amperage produced by each generator, the voltage produced by each generator, the kWs produced by each generator, and the kVAr produced by each generator to insure that the Seller maximizes the overall reliability of the Company’s System.

All equipment in this Section 3.2E shall meet the Company’s reasonable specifications for transmission of data to locations specified by the Company. The Seller shall reimburse the Company for its reasonable engineering, procurement, installation, equipment testing, maintenance costs and applicable taxes for installing and maintaining such communications, telemetering and remote control equipment (including but not limited to the remote terminal unit). The Seller shall install transducers as specified by the Company, metering, Westinghouse Flexitest test switches for transducers and metering, AC and DC sources, telephone lines and interconnecting wiring with proper identification for supervisory and communications equipment at no cost to the Company. Subsequent to the Commercial Operation Date, the Company may purchase and install additional communications, telemetering, and remote control equipment and may require the Seller to install at the Company’s expense, any reasonably necessary additional transducers, test switches, AC and DC sources, telephone lines and interconnecting wiring at any time during the Term.

(3) Meter Testing

The Company shall provide at least twenty-four (24) hours notice to the Seller prior to any test it may perform on the metering or telemetering equipment. The Seller shall have the right to have a representative present during each such test. Either Party may request additional tests in addition to the annual test provided for in Section 3.2E(l) and shall pay the cost of such additional test. If any of the metering equipment is found to be inaccurate at any time, the Company shall promptly cause such equipment to be made accurate, and the period of inaccuracy, as well as the estimate for correct meter readings, shall be determined in accordance with Section 3.2E(4).

(4) Corrections

If any test of metering equipment conducted by the Company indicates that its meter readings are in error by one percent (1%) or more, the meter readings from such equipment shall be corrected as follows: (i) determine the error by testing the meter at approximately ten percent (10%) of the rated current (test amperes) specified for the meter; (ii) determine the error by testing the meter at approximately one hundred percent (100%) of the rated current (test amperes) specified for the meter; (iii) the average meter error

ARTICLE 3

shall then be computed as the sum of one-fifth (1/5) the error determined in (i) and four-fifths (4/5) the error determined in (ii). The average meter error shall be used to adjust the bills for the amount of electric energy supplied to the Company for the previous six (6) months from the Expansion Facility, unless the Company’s or the Seller’s records conclusively establish that such error existed for a greater or lesser period, in which case the correction shall cover such actual period of error, except as specified in Section 6.5 (Billing and Payment, Adjustments).

F. Emergency Drilling Rig

The Seller shall retain a drilling rig in the State of Hawaii to allow for quick deployment in case of emergency.

G. Waste Handling

The Seller shall be responsible for the handling and proper disposal of any waste products produced by the Expansion Facility and for any costs associated therewith. The Seller shall comply with all applicable laws, rules, and regulations in executing its duties.

H. Emissions

The Seller shall be responsible for the control and consequences of any and all emissions produced as a result of operation of the Expansion Facility and for all costs associated therewith.

I. Compliance with Laws

The Seller shall at all times comply with all valid and applicable federal, state and local laws, rules, regulations, orders, permit conditions and other governmental actions (“Laws”) and shall be responsible for all costs associated therewith. To the extent any such Laws would hinder the Seller’s ability to operate the Facility in full compliance with all requirements of this Agreement, the Seller shall make commercially reasonable efforts to obtain a waiver or exemption from such Laws to the extent available.

J. Adequate Spare Parts

The Seller shall at all times keep on hand or have ready access to sufficient spare parts to maintain the Facility in a manner which provides reasonable assurance, consistent with Good Engineering and Operating Practices, that the performance of the Facility will meet the requirements of this Agreement.

ARTICLE 3

K. Periodic Meetings

The General Manager or an alternate satisfactory to the Company shall attend periodic meetings with appropriate Company representatives and be prepared to discuss Facility operations and maintenance and interface with the Company’s System operations.

L. Financial Compliance

(1) The Seller shall provide or cause to be provided to the Company on a timely basis, as reasonably determined by the Company, all information, including but not limited to information that may be obtained in any audit referred to below (the “Information”), reasonably requested by the Company for purposes of permitting the Company and its parent company, Hawaiian Electric Industries, Inc. (“HEI”), to comply with the requirements (initial and on-going) of (a) identifying variable interest entities and determining primary beneficiaries under the accounting principles of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 810, Consolidation (“FASB ASC 810”), (b) Section 404 of the Xxxxxxxx-Xxxxx Act of 2002 (“SOX 404”) and (c) all clarifications, interpretations and revisions of and regulations implementing FASB ASC 810 and SOX 404 issued by the FASB, Securities and Exchange Commission, the Public Company Accounting Oversight Board, Emerging Issues Task Force or other governing agencies. In addition, if required by the Company in order to meet its compliance obligations, the Seller shall allow the Company or its independent auditor, to audit, to the extent reasonably required, the Seller’s financial records, including its system of internal controls over financial reporting; provided that the Company shall be responsible for all costs associated with the foregoing, including but not limited to the Seller’s reasonable internal costs. The Company shall limit access to such Information to persons involved with such compliance matters and restrict persons involved in the Company’s monitoring, dispatch or scheduling of the Seller and/or the Facility, or the administration of this Agreement, from having access to such Information, unless approved in writing in advance by the Seller. Persons reviewing such Information with respect to such compliance matters shall not participate in the future pricing negotiations of amendments, modifications or clarifications of this Agreement, unless approved in writing in advance by the Seller.

(2) If there is a change in circumstances during the term of the Agreement that would trigger consolidation of the Seller’s finances on to the Company’s balance sheet, and such consolidation is not attributable to the Company’s fault, then the Parties will take all commercially reasonable steps, including modification of the Agreement, to eliminate the consolidation, while preserving the economic “benefit of the bargain” to both Parties. If for any reason,

ARTICLE 3

at any time during the term of this Agreement, by act or omission of the Seller, HELCO (and/or HELCO’s affiliates, Hawaiian Electric Company, Inc. (“HECO”) or Maui Electric Company, Limited, or Hawaiian Electric Industries, Inc.) in their good faith analysis and sole discretion are required to consolidate the Seller into its financial statements in accordance with U.S. generally accepted accounting principles, then HELCO may take any and all action necessary to eliminate consolidation, including without limitation, by immediately terminating this Agreement without fault or liability.

(3) The Company shall, and shall cause HEI to, maintain the confidentiality of the Information as provided in this Section 3.2L. The Company may share the Information on a confidential basis with HEI and the independent auditors and attorneys for HEI. (The Company, HEI, and their respective independent auditors and attorneys are collectively referred to in this Section 3.2L as “Recipient.”) If either the Company or HEI, in the exercise of their respective reasonable judgments, concludes that consolidation or financial reporting with respect to the Seller and/or this Agreement is necessary, the Company and HEI each shall have the right to disclose such of the Information as the Company or HEI, as applicable, reasonably determines is necessary to satisfy applicable disclosure and reporting or other requirements and give the Seller prompt written notice thereof (in advance to the extent practicable under the circumstances). If the Company or HEI disclose Information pursuant to the preceding sentence, the Company and HEI shall, without limitation to the generality of the preceding sentence, have the right to disclose Information to the PUC and the Division of Consumer Advocacy of the Department of Commerce and Consumer Affairs of the State of Hawaii (“Consumer Advocate”) in connection with the PUC’s rate making activities for the Company and other HEI affiliated entities, provided that, if the scope or content of the Information to be disclosed to the PUC exceeds or is more detailed than that disclosed pursuant to the preceding sentence, such Information will not be disclosed until the PUC first issues a protective order to protect the confidentiality of such Information. Neither the Company nor HEI shall use the Information for any purpose other than as permitted under this Section 3.2L.

(4) In circumstances other than those addressed in the immediately preceding paragraph, if any Recipient becomes legally compelled under applicable law or by legal process (e.g., deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar process) to disclose all or a portion of the Information, such Recipient shall undertake reasonable efforts to provide the Seller with prompt notice of such legal requirement prior to disclosure so that the Seller may seek a protective order or other appropriate remedy and/or waive compliance with the terms of this Section 3.2L. If such protective order or other remedy is not obtained,

ARTICLE 3

or if the Seller waives compliance with the provisions of this Section 3.2L, Recipient shall furnish only that portion of the Information which it is legally required to so furnish and shall use reasonable efforts to obtain assurance that confidential treatment will be accorded to any disclosed material.

(5) The obligation of nondisclosure and restricted use imposed on each Recipient under this Section 3.2L shall not extend to any portion(s) of the Information which (a) was known to such Recipient prior to receipt, or (b) without the fault of such Recipient is available or becomes available to the general public, or (c) is received by such Recipient from a third party not bound by an obligation or duty of confidentiality.

M. Notice of Certain Events

To the extent any of the following events occur and could reasonably be likely to have a material adverse effect on the Seller’s performance under this Agreement, the Seller shall provide the Company with timely notice of the occurrence of such event and the Seller’s proposed measures to ensure that such event will not lead to an Event of Default or otherwise materially impair the Seller’s ability to perform its obligations under this Agreement:

(1) Any final non-appealable order, judgment or decree is entered in any proceeding, which final order, judgment or decree provides for the payment of money in excess of five Hundred Thousand Dollars ($500,000) by the Seller, and the Seller shall not discharge the same or provide for its discharge in accordance with its terms, or procure a stay of execution thereon within sixty (60) Days from the entry thereof, and within such period of sixty (60) Days, or such longer period during which execution on such judgment shall have been stayed, appeal therefrom and cause the execution thereof to be stayed during such appeal.

(2) The Seller shall have received any notice that it is not in compliance with any of the applicable material permits that enable the Seller to operate the Facility.

3.3 Rights and Obligations of the Company

A. Dispatch of Expansion Facility Power

(1) Routine Dispatch

The Company shall have the right to dispatch up to the Available Capacity real power delivered from the Facility, and to specify reactive power, to the Company’s System, as it deems appropriate in its reasonable discretion, subject only to and

ARTICLE 3

consistent with Good Engineering and Operating Practices, the requirements set forth in Section 3.2C (Delivery of Power to the Company) of this Agreement and the Seller’s maintenance schedule determined in accordance with Section 3.2C(13) (Schedule of Outages).

If the Seller does not deliver any portion of its Firm Capacity as requested by the Company according to the terms of this Agreement, the Seller shall be subject to penalties in accordance with Section 9.1 of this Agreement.

Company Dispatch will either be through remote control by the Company’s EMS or by the Seller’s manual control under the direction of the Company’s System Operator, in each case at the Company’s discretion. The dispatch range under remote control is from twenty-two (22) to thirty-eight (38) MW, or from twenty-two (22) MW to the Available Capacity if different than thirty-eight (38) MW. Notwithstanding anything to the contrary, the power produced by the Expansion Facility shall always be subject to remote or manual dispatch.

The minimum routine dispatch under remote control by the Company EMS shall be thirty (30) MW on-peak and twenty-two (22) MW off-peak on an hourly average basis (providing the Available Capacity is greater than the above minimum dispatch level; this amount may be adjusted if the Existing Facility is unable to provide the required amount of energy for the first block as described in Section 5.1) except under non-routine system conditions requiring significant balancing operations (i.e.; system disturbances, outage conditions, and other conditions creating frequency deviations and power imbalances) and as further described in Minimum Load Capability in Section 3.2C (Delivery of Power to the Company).

Refusal or inability of the Seller to provide the output required by the Company Dispatch shall result in the assumption that the Available Capacity is equal to the actual net energy delivered from the Expansion Facility and the Existing Facility. This shall be considered at reduced Available Capacity for the purpose of calculating the Seller’s EAF and EFOR. The size of the derating will be determined by subtracting the Available Capacity from the Firm Capacity, from the time the inability to meet the dispatch request occurs until such time as the Seller demonstrates the capacity by the Expansion Facility and Existing Facility as requested by the Company. The Seller shall utilize the full capability of the Expansion Facility to satisfy its obligation to deliver up to the Firm Capacity in accordance with Company Dispatch.

The System Operator may require dispatch below the levels of the remote dispatch, under the Seller’s manual control, under disturbances or other unusual operating conditions which could

ARTICLE 3

be mitigated or addressed by the reduction of the Facility in the judgment of the System Operator, such as, but not limited to: excess energy conditions due to abnormal operating conditions such as could be caused by unexpected loss of load, system over-frequency, transmission equipment overload or risk of transmission overloads due to contingencies, and high voltages in the vicinity of the interconnection.

(2) Dispatch Forecast

The Company shall provide the Seller with a forecast of the following: the annual dispatch which shows the amount of energy the Company expects the Facility to produce on a monthly basis for the following calendar year, no later than sixty (60) Days prior to the anticipated Commercial Operation Date for the first Contract Year, and prior to September 1 for each Contract Year thereafter. The Company’s failure to comply with the foregoing forecast provisions shall not affect the Company’s right to dispatch the Facility pursuant to this Section 3.3A (Dispatch of Expansion Facility Power).

B. Voltage Regulation

The Seller shall provide voltage regulation for the Facility at the Point of Interconnection. The voltage regulation shall be able to maintain voltage by utilizing the entire range of the Facility’s MVAr capability. The System Operator shall be able to specify the target voltage remotely from the EMS.

C. Demonstration of Facility Requirements

The Company shall have the right at any time, other than during start-up periods, maintenance or other outages, to notify the Seller in writing of the Seller’s failure, as observed by the Company and set forth in such written notice, to meet the requirements specified in Section 3.2C and to require documentation or testing to verify compliance. A period of mutually agreed time, not to exceed thirty (30) Days, unless mutually extended by Parties, will be allowed to address the problem following the written notification. Failure to address the problem within this period will result in the actions described in Article 8.

D. The Company Right to Require Independent Engineering Assessment

(1) Implementation of Independent Engineering Assessment

If (A) the Company determines that it has “reasonable cause” to believe that the Seller is failing to operate or maintain

ARTICLE 3

the Facility in accordance with Good Engineering and Operating Practices and that such failure is likely to result in a failure to meet the performance standards set forth in Section 3.2C (Delivery of Power to the Company); (B) the Seller is in breach of this Agreement with respect to the performance or operation of the Facility and has not cured such breach within the time limits specified in Article 8 (Default); or (C) otherwise required by Article 8, then the Company shall notify the Seller in writing that a Dispute (as defined in Section 16.1 (Good Faith Negotiations)) exists, and within thirty (30) Days after the date of such written notice (unless the Parties agree upon a different date) the presidents, vice presidents, or authorized delegates from both the Seller and the Company having full authority to settle the Dispute(s), shall personally meet in Hawaii and attempt in good faith to resolve the Dispute(s). If the Dispute(s) under this Section 3.3D(1) are not resolved in thirty (30) days, then the Company may require that the practices in question be assessed by a qualified professional engineering firm to be chosen from the Qualified Independent Engineering Companies List attached to this Agreement as “Attachment H” and revised from time to time under Section 3.3D(2) (Qualified Independent Engineering Companies). For purposes of this Section 3.3D(1), “reasonable cause” shall mean, in the Company’s determination, the Seller’s failure to operate the Facility in accordance with Section(s) 2.1D (Electric Specifications), 3.2A(6) (Facility Protection Equipment), 3.2B(1-3) (Standards, Functioning Protective Equipment and Personnel and System Safety) and 3.2C (Delivery of Power to the Company), which the Company brings to the Seller’s attention and which the Seller fails to remedy in accordance with Good Engineering and Operating Practices within ninety (90) Days thereafter. The Parties shall promptly undertake to agree on a firm to be used from the Qualified Independent Engineering Companies List; provided, however, that if such agreement is not reached within seven (7) Days after the Company gives notice to the Seller that it is invoking its rights under this Section 3.3D, the firm shall be chosen from the Qualified Independent Engineering Companies List by the Company. The engineering firm selected shall make its determination (an “Independent Engineering Assessment”) as to whether the practices in question conform to Good Engineering and Operating Practices as promptly as possible under the circumstances, provided that the engineering firm selected shall use commercially reasonable efforts to make such determination within one hundred and twenty (120) Days after the date that the engineering firm is selected, unless the Parties agree upon an earlier or later date. If such determination is that the practices in question do not so conform, the engineering firm shall recommend necessary actions by the Seller to bring it within Good Engineering and Operating Practices. If the engineering firm’s recommendation requires action by the Seller to change its practices, the Seller shall take such actions. Where action by the Seller has been recommended, the engineering firm shall determine, after reasonable

ARTICLE 3

consultation with the Seller within thirty (30) Days (or such longer period as deemed appropriate by such engineering firm) after its recommendation is first made, whether the Seller has taken adequate action to carry out such recommendation. If the engineering firm then certifies that the Seller has failed to take adequate action, the Company shall notify the Seller in writing of such certification and the basis therefor. Such notice shall state in bold letters that failure to respond adequately can lead to termination of this Agreement within thirty (30) Days. If within thirty (30) Days of such actual written notice to the Seller, the Seller has not begun to implement such recommendation, such failure shall be an Event of Default under Section 8.1A(5) (Events of Default; Default by the Seller). If within such thirty (30) Day period the Seller does begin to implement such recommendation, the engineering firm shall monitor whether the implementation thereof is being diligently pursued. If, after reasonable consultation with the Parties involved in such implementation, the engineering firm determines that such implementation is not being diligently pursued, it shall promptly so certify the Company. The Company shall thereupon promptly notify the Seller in writing of such certification and the basis therefor (the “Second Notice”). Such Second Notice shall state in bold letters that failure to respond adequately can lead to termination of this Agreement after thirty (30) Days. If at any time after the thirty (30) Day period commencing with receipt of the Second Notice by the Seller, the engineering firm again certifies to the Company that implementation of its recommendation is not being diligently pursued, such certification shall constitute an Event of Default by the Seller under Section 8.1A(5) (Events of Default; Default by the Seller). The Seller shall bear all costs of the engineering firm’s services unless the firm’s initial recommendation is that the practices in question were in accordance with Good Engineering and Operating Practices, in which case the Company shall bear all costs of the engineering firm’s services.

(2) Qualified Independent Engineering Companies

The Company and the Seller shall agree on a list of Qualified Independent Engineering Companies which shall be attached hereto as “Attachment H” containing the names of engineering firms which both Parties agree are fully qualified to perform the Independent Engineering Assessment under Section 3.3D(1). At any time, except when an Independent Engineering Assessment is being made under Section 3.3D(1), either Party may remove a particular company from the Qualified Independent Engineering Companies List by giving written notice of such removal to the other Party. However, neither Party may remove a company or companies from the Qualified Independent Engineering Companies List without approval of the other Party if such removal would leave the Qualified Independent Engineering Companies List with less than two (2) companies. During

ARTICLE 3

January of each year, both Parties shall review the current Qualified Independent Engineering Companies List and give notice to the other Party of any proposed additions to the Qualified Independent Engineering Companies List and any intended deletions. Intended deletions shall be effective upon receipt of notice by the other Party, provided that such deletions do not leave the Qualified Independent Engineering Companies List with less than two (2) companies. Proposed additions to the Qualified Independent Engineering Companies List shall automatically become effective thirty (30) Days after notice is received by the other Party unless written objection is made by such other Party within said thirty (30) Days. By mutual agreement between the Parties, a new company or companies may be added to the Qualified Independent Engineering Companies List at any time.

ARTICLE 3

ARTICLE 4 - SUSPENSION OR REDUCTION OF DELIVERIES

4.1 Initiation by the Company

In the event that the Company determines and notifies the Seller that a condition exists which has a material adverse physical impact on the Company’s System or the equipment of the Company’s customers and which, in the Company’s sole judgment, requires a change in electricity deliveries by the Seller, the Seller shall immediately suspend or reduce electricity deliveries as requested by the Company’s System Operator upon remote control, oral or written notice, as appropriate, to the extent required to eliminate such adverse impact. If the Company’s System Operator determines that an immediate danger to personnel or equipment exists, the Company’s System Operator may remotely separate the Expansion Facility from the Company’s System by tripping the Expansion Facility’s main breakers as shown in Attachment A-1 via the EMS without prior notice.

A. Expansion Facility Problems

If the operation of the Expansion Facility is causing or substantially contributing to an adverse condition described in Section 4.1 due to the failure to meet the requirements of Section 2.1D (Electric Specifications), Sections 3.2B(l) (Standards), 3.2B (2) (Functioning Protective Equipment), or 3.2B (3) (Personnel and System Safety), Section 3.2C (Delivery of Power to the Company), or Good Engineering and Operating Practices, the Seller shall, at its own cost, modify its electric equipment or operations to the extent necessary to promptly resume full deliveries of electricity at the quality of electric service required. Upon the Seller’s reasonable request, the Company will modify the Company’s System to assist the Seller in resuming full deliveries, provided that the Seller reimburses the Company for all costs and expenses incurred by the Company in making such modifications; provided, however, that to the extent that defects in the Company’s facilities, or the Company’s actions taken subsequent to the date of execution of the agreement on interconnection details, are not consistent with Good Engineering and Operating Practices and are causing or contributing to such conditions, the Company shall not be entitled to such reimbursement.

If the Expansion Facility reports a deration, Forced Outage or Unit Trip, the Seller will provide, within five (5) Business Days thereafter, a report to the Company of the cause, including data to support the conclusion, and actions taken or to be taken to correct the cause.

The Company and the Seller shall use all reasonable efforts to minimize the frequency and duration of any such conditions and

ARTICLE 4

shall seek to promptly restore full deliveries of electricity in accordance with the terms of this Agreement.

B. Company System Problems

In the event that a system emergency, safety problem, Forced Outage or period of unscheduled maintenance on the Company’s System which cannot reasonably be coordinated with the Seller’s period of maintenance or shutdown is the cause of an adverse condition, the Company shall use all reasonable efforts to limit the duration of any such occurrence or take other appropriate action so that full deliveries of electricity by the Seller in accordance with the terms of this Agreement can be restored as soon as practicable. If the Company suspends or reduces deliveries from the Expansion Facility pursuant to this Section 4.1B it shall, as soon as practicable, provide a written statement to the Seller setting forth the reasons for such suspension or reduction requests and the likely duration thereof.

4.2 No Obligation to Accept Energy

A. During periods in which the Seller has reduced or suspended deliveries of electricity as requested by the Company or if the Expansion Facility has been separated from the Company’s System pursuant to Section 4.1, in either case in circumstances described in Section 4.1A, the Company shall have no obligation to accept any energy which might otherwise have been received from the Expansion Facility during such period, and the Company shall have no obligation to pay for energy which otherwise would have been available or received from the Expansion Facility during such period, and the Expansion Facility shall be considered unavailable during such period for purposes of calculating the Seller’s EAF, EFOR and Unit Trips.

B. During periods in which the Seller has reduced or suspended deliveries of electricity as requested by the Company or in which the Expansion Facility has been separated from the Company’s System pursuant to Section 4.1, in either case in circumstances described in Section 4.1B, the Company shall have no obligation to accept any energy which otherwise would have been received from the Expansion Facility during such period. However, the Company shall pay for energy (to the extent accepted) in accordance with Section 5.1, and the duration of the period of separation will not be counted against the Seller’s EAF, EFOR and Unit Trips.

4.3 Initiation by the Seller

If the Seller suspends, or can reasonably anticipate the need to suspend or substantially reduce, deliveries of electricity below the level called for by Company Dispatch pursuant to Section 3.3A (Dispatch of Expansion Facility Power) for any reason other

ARTICLE 4

than a request by the Company pursuant to Section 4.1B, it shall provide immediate oral notice and subsequent written notice to the Company as soon as practicable, containing a reasonably detailed statement of the reasons for such suspension or reduction and the likely duration thereof. The Seller shall use its reasonable best efforts to restore full deliveries of electricity as soon as practicable.

ARTICLE 4

ARTICLE 5 - RATES FOR PURCHASE

5.1 Capacity and Energy Purchased by the Company

A. General

(1) Subject to the other provisions of this Agreement, the Company shall accept and pay for electrical energy generated by the Expansion Facility and delivered to the Company and shall make capacity payments to the Seller as set forth herein. Included in the purchase and sale of energy and capacity are all of the Environmental Credits associated with the Net Electric Energy Output. Electrical energy and capacity (demand) shall be metered in accordance with Section 3.2E (Metering, Generator Remote Control, Data Acquisition/Communications), and such metering shall constitute the official and legal measurements for any payments hereunder.

(2) After the PUC Approval Date but prior to the Commercial Operation Date, the Company will use its reasonable efforts to accept energy from the Expansion Facility during the Acceptance and Capacity Test conducted pursuant to Section 3.2C(12) and Attachment D. The Seller shall provide to the Company a written notice, detailed, and comprehensive start-up plan thirty (30) Days in advance of delivering any energy to the Company and shall provide written notice to the Company of any changes to such start-up plan as soon as reasonably practicable, but no less than three (3) Days in advance of implementing those changes. The Seller and Company shall coordinate such start-up and testing so as to minimize any additional costs to the Company as a result of departing from economic dispatch in the operation of the Company’s electrical system. Electric energy delivered to the Company pursuant hereto shall be considered non-firm, unscheduled energy, but must meet all of the quality standards established in this Agreement. The Company shall only pay Energy Charges for any such energy actually delivered from the Expansion Facility.

(3) If, after the PUC Approval Date but prior to the Commercial Operation Date, the Expansion Facility is ready to begin delivering energy to the Company but the Company has not completed the installation, testing and start-up of its Interconnection Facilities (including in particular its Substation) and, as a result, is unable to accept energy from the Expansion Facility during the Capacity Test pursuant to the preceding paragraph and thereafter, then the Company and the Seller shall promptly meet to determine if there is an alternate temporary means by which the Expansion Facility can deliver energy to the Company by bypassing the Company Interconnection Facilities. If the Parties conclude that there is such alternate means, at Seller’s option, they shall use their commercially reasonable best efforts to design, install, permit if required, test and operate such alternate means to deliver such energy

ARTICLE 5

from the Expansion Facility to the Company until such time that the Company’s Interconnection Facilities become fully operational. The Parties shall accomplish this work as quickly as possible. The Seller shall be liable and pay for the full cost of developing and constructing such alternate means of delivery. Such means shall include provisions for separate metering of Existing and Expansion Facilities as required to determine payment in accordance with Section 5.1C (Energy Charge).

(4) The Company will, to the extent practicable, use its commercially reasonable efforts to cause the Company’s Interconnection Facilities to be fully operational on or before the Commercial Operation Date, provided that the Seller promptly pays to the Company when due, the Total Estimate Interconnection Cost as set forth in Attachment A-3. The Parties will coordinate, to the greatest extent practicable, their development, construction and testing activities of the Expansion Facility in the case of the Seller and the Interconnection Facilities in the case of the Company.

B. Calculation of Energy and Firm Capacity Payments

(1) Under this Agreement and the Current PPA, the Seller is to deliver a total of thirty-eight (38) MW of energy to the Company. The equipment from the Expansion Facility will be used to provide up to (but not to exceed) eight (8) MW of the thirty-eight (38) MW capacity to be provided from the Existing Facility and the Expansion Facility. The equipment from the Expansion Facility may also be used to provide energy under the Current PPA.

(2) The payments for the energy provided by the Seller from the Facility shall be paid for under the Current PPA or this Agreement as follows:

(a) The first (1st) twenty-five (25) MW on-peak block and the first (1st) twenty-two (22) MW off-peak block of energy shall be provided from the Existing Facility under the Current PPA. In no event shall the energy from the Expansion Facility be paid for under the Current PPA energy rates for this block of energy. To the extent that the first (1st) twenty-five (25) MW on-peak block and first (1st) twenty-two (22) MW off-peak block of energy is not available from the Existing Facility under the Current PPA, any obligation of HELCO to take energy under the first (1st) twenty-five (25) MW on-peak block and the first (1st) twenty-two (22) MW off-peak block shall be reduced accordingly.

(b) The twenty-five to thirty (25-30) MW on-peak block and the twenty-two to twenty-seven (22-27) MW off-peak block may be provided by the Existing Facility under the Current PPA and/or by the Expansion Facility under the New PPA.

ARTICLE 5

(c) The thirty to thirty-eight (30-38) MW on-peak block and the twenty-seven to thirty-eight (27-38) MW off-peak block may be provided by the Existing Facility under the Current PPA and/or by the Expansion Facility under the New PPA.

(d) Example - If the Seller provides twenty-one (21) MW from its Existing Facility and eight (8) MW from its Expansion Facility on-peak (total of twenty-nine (29) MW), then the Energy payments shall be calculated as follows:

(i) twenty-one (21) MW shall be priced at the first (1st) twenty-five (25) MW block (based on on-peak avoided cost and minimum rate) under the Current PPA;

(ii) five (5) MW shall be priced at the twenty-five to thirty (25-30) MW block (11.8 cents/kWh, escalated) under the Current PPA; and

(iii) three (3) MW shall be priced at the thirty to thirty-eight (30-38) MW block (either nine (9) cents/kWh or six (6) cents/kWh, escalated) under this Agreement.

(e) Example - If the Seller provides twenty-one (21) MW from its Existing Facility and eight (8) MW from its Expansion Facility off-peak (total of twenty-nine (29) MW), then the Energy payments shall be calculated as follows:

(i) twenty-one (21) MW shall be priced at the first (1st) twenty-two (22) MW block (based on off-peak avoided cost and minimum rate) under the Current PPA;

(ii) five (5) MW shall be priced at the twenty-two to twenty-seven (22-27) MW block (11.8 cents/kWh, escalated) under the Current PPA; and

(iii) three (3) MW shall be priced at the twenty-seven to thirty-eight (27-38) MW block (six (6) cents/kWh, escalated) under this Agreement.

ARTICLE 5

C. Energy Charge

The Energy Charge under this Agreement shall be computed as follows:

(1) The amount of energy delivered at any particular time shall be calculated as follows:

For On-Peak periods –

· If the amount of energy delivered from the Existing Facility is twenty-five (25) MW or greater, then the amount of energy delivered will be the sum of the energy delivered from Existing Facility and the Expansion Facility less thirty (30) MW. If the sum of the Existing Facility and the Expansion Facility is less than or equal to thirty (30) MW, then the energy delivered under this Agreement is zero (0).

· If the amount of energy delivered from the Existing Facility is less than twenty-five (25) MW, then the amount of energy delivered will be the energy delivered from Expansion Facility less five (5) MW. If the Expansion Facility is less than or equal to five (5) MW, then the energy delivered under this Agreement is zero (0).

For example, if during a fifteen (15) minute interval the Seller provides twenty-eight (28) MW from its Existing Facility and five (5) MW from its Expansion Facility, seven hundred fifty (750) kWh will be applied to this Agreement, and seven thousand five hundred (7,500) kWh will be applied to the Current PPA. If Seller provides twenty-eight (28) MW from its Existing Facility and one (1) MW from its Expansion Facility, zero (0) kWh will be applied to this Agreement and seven thousand two hundred fifty (7,250) kWh will be applied to the Current PPA.

ARTICLE 5

For Off-Peak periods –

· If the amount of energy delivered from the Existing Facility is twenty-two (22) MW or greater, then the amount of energy delivered will be the sum of the energy delivered from Existing Facility and the Expansion Facility less twenty-seven (27) MW. If the sum of the energy delivered from Existing Facility and the Expansion Facility is less than or equal to twenty-seven (27) MW, then the energy delivered under this Agreement is zero (0).

· If the amount of energy delivered from the Existing Facility is less than twenty-two (22) MW, then the amount of energy delivered will be the energy delivered from Expansion Facility less five (5) MW. If the energy delivered from Expansion Facility is less than or equal to five (5) MW, then the energy delivered under this Agreement is zero (0).

(2) Price for energy delivered during On-Peak Hours

(a) Up to and including 30,000 MWh/year - nine (9) cents/kWh; or

(b) Over 30,000 MWh/year - six (6) cents/kWh

(3) Price for energy delivered during Off-Peak Hours

(a) Off-Peak Hours – six (6) cents/kWh

(4) The six (6) cents/kWh and nine (9) cents/kWh payments rates for energy under this Section shall be escalated at a rate of 1.5% a year. The payment rates shall be rounded to four (4) decimal places (e.g. $0.0000). Escalation will begin on January 1 of the second Contract Year and annually thereafter; provided, however, that the escalation rate for the second Contract Year shall be determined by the following formula:

Escalation Rate = 0.015 * [CD/365]

Where “CD” is the number of calendar Days from the Commercial Operation Date of the Expansion Facility through the end of the first Contract Year. For example, if the Commercial Operation Date is September 1, 2010, then “CD” will equal the number of days from September 1, 2010 through December 31, 2011.

ARTICLE 5

For Contract Years three (3) through the end of the Term, the escalation rate shall be 1.5% a year.

(5) Proration for first partial year. If the Commercial Operation Date does not occur on January 1, then for the first partial calendar year of commercial operation (i.e. from the Commercial Operation Date to December 31 of that partial first calendar year), the price for energy delivered in the thirty to thirty-eight (30-38) MW block of energy during On-Peak Hours shall be calculated as follows:

(a) Up to and including XXX MWh (rounded to three (3) decimal places) for that partial first calendar year - nine (9) cents/kWh; or

(b) Over XXX MWh (rounded to three (3) decimal places) for that partial first calendar year - six (6) cents/kWh.

Where XXX is equal to 82.191 multiplied by the number of days starting with the Commercial Operation Date through and including December 31 of that year. For example, if the Commercial Operation Date is October 15, then XXX would be 6,410.960 MWh calculated as follows:

6,410.960 MWh = (30,000MWh/365 days) x (the number of days starting with and including October 15, up through and including December 31 (total of seventy-eight (78) days))(rounded to three (3) decimal places)

and the On-Peak MWh energy rates would be based on the MWh purchases:

(a) For every kWh purchased up to and including 6,410.960 MWh for that partial first calendar year the On-Peak energy payment rate is nine (9) cents/kWh; and

(b) For every kWh purchased over 6,410.960 MWh for that partial first calendar year the On-Peak energy payment rate is six (6) cents/kWh.

The Off-Peak Hours energy rate shall remain the same at six (6) cents/kWh.

ARTICLE 5

D. Capacity Charge

The Seller shall be paid a Capacity Charge for the Available Capacity and other services provided herein. The Capacity Charge shall be computed as follows:

(1) Provided that the Firm Capacity is at least thirty-eight (38) MW pursuant to the terms and conditions of the Agreement, the Seller will be paid two million dollars ($2,000,000) a year for the eight (8) MW of Firm Capacity generated by the Expansion Facility or, in other words, Two Hundred and Fifty Thousand Dollars ($250,000) per megawatt per year or $20,833.33/MW/month. Accordingly, the monthly Capacity Charge Rate shall be $20,833.33/MW/month based on eight (8) MW of Firm Capacity. The Capacity Charge shall be adjusted depending on the amount of Firm Capacity available to the Company.

(2) The monthly Capacity Charge Rate of $20,833.33/MW/month under this Section shall be escalated at a rate of 1.5% a year. The per megawatt rate shall be rounded to four (4) decimal places (e.g. $0.0000). Escalation will begin on January 1 of the second Contract Year and annually thereafter; provided, however, that the escalation rate for the second Contract Year shall be determined by the following formula:

Escalation Rate = 0.015 * [CD/365]

For Contract Years three (3) through the end of the Term, the escalation rate shall be 1.5% a year.

(3) The base capacity for the Capacity Charge (monthly) shall be the average Available Capacity for the month from the Facility less thirty (30) MW, provided that the base capacity shall not be greater than eight (8) MW or less than zero (0) MW.

(4) Calculation of the Capacity Charge (monthly). The Capacity Charge (monthly) shall be based on the monthly Available Capacity of the Facility. On and after the Commercial Operation Date, the monthly Capacity Charge shall be computed by the following formula:

Capacity Charge (monthly) = (average Available Capacity for the month - 30(MW)) x Capacity Charge Rate

ARTICLE 5

In no event shall the Capacity Charge (monthly) be less than zero (0). In other words, if the Capacity Charge (monthly) is a negative number, the Capacity Charge (monthly) for that particular period shall be zero (0). For months containing any Days of the two (2) fourteen (14) Day maintenance periods specified in Section 3.2C(1), the average Available Capacity for each such Day shall be calculated using the following factor (average Available Capacity for the maintenance period Day (not to exceed 8 MW) + 30(MW)). For example, if the average Available Capacity for the Facility on one (1) Day of the allowed fourteen Day maintenance period is seven (7) MW, then the average Available Capacity for that Day to be used in the average Available Capacity calculation for the month shall be thirty-seven (37) MW (7 MW+30MW).

(5) Acceptance and Capacity Tests. The Capacity Charge under this Section 5.1D, shall begin on the Commercial Operation Date.

(6) Initial Capacity Shortfall; Corrective Period. In the event the Commercial Operation Date is achieved and the initial Capacity tests conducted in accordance with Attachment D demonstrate that the Facility is unable to provide a Firm Capacity equal to the Committed Capacity at the time of the Commercial Operation Date, the following provisions shall apply:

(a) the Commercial Operation Date Deadline will be deemed to be met, provided that the Seller shall, during the next twelve (12) months or such shorter period (“Corrective Period”) use commercially reasonable efforts to increase the Facility’s capacity level to the Committed Capacity as verified through a Capacity Test in accordance with the procedures in Attachment D. During the Corrective Period, the Capacity Charge shall be calculated in accordance with the Capacity Charge formula using the Firm Capacity determined in the initial Capacity Test as the Firm Capacity in the formula.

(b) if the Expansion Facility has not achieved its portion of the Committed Capacity after the Corrective Period, then the Firm Capacity achieved shall be deemed to be the Expansion Facility’s portion of the Committed Capacity and the Parties shall make appropriate pro-rata adjustments to the Capacity Charge, and the amount of such Firm Capacity cannot be increased by subsequent Capacity Tests unless mutually agreed to by the Parties in their sole and absolute discretion.

(7) The Company shall not be required to pay any additional capacity payment for any additional power supplied by the Seller, either at the Company’s or the Seller’s request.

ARTICLE 5

(8) A failure by the Seller to provide the required Firm Capacity to the Company shall result in the reduction in the capacity payment due to the Seller from the Company in accordance with Section 5.1D of this Agreement. The Company shall not have any obligation to pay capacity payments to the Seller for periods in which the Seller is unable to fulfill its obligations under this Agreement, including but not limited to circumstances which are subject to Article 17 of this Agreement relating to Force Majeure.

(9) Permanent Reduction in Firm Capacity. If, at any time after the Commercial Operation Date, (1) the Facility is continuously unable to achieve the Firm Capacity level for a period of eighteen (18) or more consecutive months, or (2) the Facility is unable to achieve an average Available Capacity of ninety percent (90%) of the established Firm Capacity level for a period of eighteen (18) or more consecutive months, then the Company or the Seller, at the option of either Party, shall have the right to give written notice to the other Party asking that a Capacity Test consistent with Good Engineering and Operating Practices and reasonably satisfactory to both Parties be conducted on the Facility pursuant to Section 3.2C(12) and Attachment D. If the Capacity Test demonstrates that the Facility is unable to deliver Firm Capacity continuously, then the Firm Capacity amount shall be revised to reflect the capacity established by the Capacity Test as the maximum firm capacity that the Facility is capable of delivering under Company Dispatch. The maximum firm capacity thus established shall thereupon become the Firm Capacity under this Agreement, and this revised Firm Capacity will be used in the EAF and EFOR calculations. The revised Firm Capacity will be effective with the next Monthly Invoice following the date of receipt of the results of the Capacity Test. In the event that the Capacity Test demonstrates that the Facility is unable to continuously deliver more than thirty (30) MW, then the Firm Capacity under this Agreement shall be revised to thirty (30) MW. In no case shall the Firm Capacity under this Agreement be revised to lower than thirty (30) MW. Firm Capacity which is reduced through a Capacity Test (or otherwise reduced pursuant to this section) cannot be increased by subsequent Capacity Tests unless otherwise agreed to by both Parties in their sole and absolute discretion.

E. Minimum Delivery Guarantee by the Company

(1) The Company shall purchase a minimum of 18,000 on-peak MWh (from the thirty (30) to thirty-eight (38) MW block of energy) each Contract Year (“Minimum Purchase Requirement”) from the Seller under Company Dispatch subject to the provisions of Sections 3.2.B(3), Article 4 and 5.1E of this Agreement.

(2) The 18,000 MWh Minimum Purchase Requirement shall be reduced for any given Contract Year to the extent that:

ARTICLE 5

(a) The Available Capacity of the Facility is less than thirty-eight (38) MW for any reason other than the annual overhaul period. The 18,000 MWh shall be reduced by the following formula:

Amount of reduction = ((Average On-Peak Available Capacity of the Facility for the month – 30MW) – 8MW) * (14 hours * Actual number of days in that month)

[Note: The amount of the reduction is expressed as a negative number.]

In no event shall that portion of the formula (Average On-Peak Available Capacity of the Facility for the month – 30MW) be less than zero (0). In other words, if the Average On-Peak Available Capacity of the Facility for the month is less than thirty (30) MW, then the portion of the formula (Average On-Peak Available Capacity of the Facility for the month – 30MW) for that particular period shall be zero (0). For example, if the Average On-Peak Available Capacity for a month is twenty-nine (29) MW, then the formula would read

Amount of reduction = ((0)-8) * (14 hours * Actual number of days in that month)

(b) During the annual overhaul periods, the Seller shall provide at least eight (8) MW of Available Capacity from the Facility. To the extent that the Seller is unable to have the minimum of eight (8) MW of Available Capacity from the Facility, the 18,000 MWh amount shall be reduced by the difference between eight (8) MW and the Available Capacity.

(3) In determining if the Company meets the Minimum Purchase Requirement, the Company’s energy purchases can be calculated using a three (3) year rolling average.

(4) The Company can use off-peak MWh of energy generated from the Expansion Facility (regardless of whether the pricing for such energy is under this Agreement or the Fifth Amendment) to help fulfill the Minimum Purchase Requirement using a conversion ratio of one and one half (1.5) off-peak MWh to fulfill one (1.0) on-peak MWh Minimum Purchase Requirement.

ARTICLE 5

(5) The Company shall be able to schedule the delivery of the Seller’s energy on an hourly basis to ensure the Minimum Purchase Requirement of energy.

F. Hawaii General Excise Tax

The Company shall not be liable for payment of the applicable Hawaii General Excise Tax levied and assessed against the Seller as a result of this Agreement. The rates and charges in this Article 5 shall not be adjusted by reason of any subsequent increase or reduction of the applicable Hawaii General Excise Tax.

G. No Payment of Emission Fees

The Company shall not be liable for payment of the applicable air pollutant emissions fees imposed by the DoH or U.S. Environmental Protection Agency on the Seller as a result of operating or having the potential to operate the Facility.

H. No Payment of Other Taxes or Fees

The Company shall not be liable for payment of, nor reimbursement of, any payment of any new or modified tax or fee imposed upon the Seller by any governmental body.

ARTICLE 5

ARTICLE 6 - BILLING AND PAYMENT

As long as this Agreement is in effect, the provisions of this Article 6 shall supersede and replace the billing and payment provisions under the Current PPA. The provisions of this Article 6 shall govern the payments to the Seller under both the Current PPA, as may be amended from time to time, and this Agreement.

6.1 Monthly Invoice

By the fifth (5th) Business Day of each Calendar Month, the Company shall provide the Seller with the appropriate data for the Seller to compute the payment due for electricity delivered to the Company in the preceding Calendar Month as determined in accordance with this Agreement and the Current PPA. The Seller shall compute the energy payment and Capacity Charge (monthly) and submit by the tenth (10th) Business Day of the month an invoice (“Monthly Invoice”) for the energy payment and Capacity Charge (monthly) to be paid to the Seller for the preceding Calendar Month. Each Monthly Invoice shall include the Seller’s backup data for the computation of the energy payment and Capacity Charge (monthly) available as of the date of such Monthly Invoice. The Parties shall not be limited to reported operational data in calculating the monthly payment(s), and the Parties may make that calculation on the basis of all information available to the Parties, including results of seasonal capacity tests, results of ramp rate tests, and Facility response to requests for changes in operation. Unless and until the Company designates a different address, the Monthly Invoice shall be delivered to:

6.2 Payment

Upon timely receipt of the Monthly Invoice from the Seller, by the twentieth (20th) Business Day of each month (but no later than the last Business Day of that month if there are less than 20 Business Days in that month), the Company shall pay such monthly energy payment and Capacity Charge (monthly) as determined in accordance with this Agreement and the Current PPA, or provide to the Seller an itemized statement of its objections to all or any portion of such Monthly Invoice and pay any undisputed amount. The timing of the Company’s obligations under this Section 6.2 shall be extended by a period of time equal to the number of Days the Seller

ARTICLE 6

submits Monthly Invoice after the tenth (10th) Business Day of the month.

6.3 Billing Disputes

Either Party may dispute invoiced amounts, but shall pay to the other Party at least the undisputed portion of invoiced amounts on or before the invoice due date. To resolve any billing dispute, the Parties shall use the procedures set forth in Article 16. When the billing dispute is resolved, the Party owing shall pay the amount owed within five (5) Business Days of the date of such resolution, with late payment interest charges calculated on the amount owed in accordance with the provisions of Section 6.4. Undisputed and non-offset portions of amounts invoiced under this Agreement shall be paid on or before the due date.

6.4 Interest

Notwithstanding all or any portion of such invoice in dispute, any payment not made to the Seller by the twentieth (20th) Business Day of each calendar month (or the last Business Day in that month if there are less than twenty Business Days in that month) shall accrue interest at the average daily Base Rate plus two percent (2%) for the period until the outstanding interest and invoice amounts (or amounts due to the Seller if determined to be less than the invoiced amounts) are paid in full. Partial payments shall be applied first to outstanding interest and then to outstanding invoice amounts.

6.5 Adjustments

In the event adjustments are required to correct inaccuracies in Monthly Invoices, the Party requesting adjustment shall use the method described in Section 3.2E(4) (Metering; Corrections), if applicable, to determine the correct measurements, and shall recompute and include in the Party’s request the amounts due during the period of such inaccuracies. Except as noted below, the difference between the amount paid and that recomputed for each Monthly Invoice affected shall be paid, or repaid, with interest from the date that such Monthly Invoice was payable or was objected to by the Party responsible for such payment within thirty (30) Days following its receipt of such request, until the date that such recomputed amount is paid at the average daily Base Rate for the period. All claims for adjustments shall be waived for any deliveries of electricity made more than thirty-six (36) months preceding the date of any such request.

ARTICLE 6

6.6 Other Payments

Any amounts due from either Party under this Agreement other than monthly energy charges and Capacity Charge (monthly) shall be paid or objected to within thirty (30) Days following receipt from either Party of an itemized invoice setting forth, in reasonable detail, the basis for such invoice.

6.7 Offsets

In the event that a Party (“Nonpaying Party”) fails to pay the other Party any amount when due and owed under this Agreement (less any amounts disputed in good faith pursuant to Article 16) and fails to remedy such non-payment within thirty (30) Days after written demand therefor by the Party owed the amount, the Party owed the amount may at any time thereafter offset against any and all amounts that may be due and owed to the Nonpaying Party, any amount that the Nonpaying Party owes the Party conducting the offset. Any Party asserting an offset shall provide a written explanation of the amount of the offset and the reason for the offset.

and warrant that (i) all records of such Party, its partners, members, or affiliates pertaining to the negotiation, administration, and enforcement of this Agreement shall be maintained in the possession of such Party for no fewer than seven (7) years, and (ii) each of its officers, employees, consultants, general partners, or managing members shall submit to the jurisdiction of the arbitrator(s) and shall comply with all orders and subpoenas issued with respect to the production of witnesses or evidence at and/or prior to the hearing.

ARTICLE 16

ARTICLE 17 - FORCE MAJEURE

17.1 Definition

The term “Force Majeure” as used in this Agreement means an event not reasonably anticipated as of the date of this Agreement, which (a) is not within the reasonable control of the Party affected thereby, (b) could not have been avoided by the affected Party’s exercise of due diligence or operation in accordance with Good Engineering and Operating Practices, (c) is not the result of the failure to act or the negligence of the affected Party, and (d) the affected Party is unable to overcome by the exercise of due diligence. To the extent that such event satisfies the test set forth in the preceding sentence, Force Majeure includes: acts of God, fire, flood, explosion, civil disturbance, sabotage, terrorism, hurricanes, tornadoes, lightning, earthquakes, volcanic eruptions, war, Catastrophic Equipment Failure and action or restraint by court order or governmental authority; provided that to the extent possible, the Facility shall be designed for seismic, tropical storm, hurricane, flooding, and volcanic eruption conditions as appropriate for its location in order to provide for the Firm Obligation; and provided that none of the following constitute Force Majeure:

(i)	strikes or labor disturbances occurring at the Site, except to the extent such strikes or labor disturbances at the Site are directly related to strikes or labor disturbances that are simultaneously disrupting other business operations on the island of Hawaii;

(ii)	any acts or omissions of any third party, including, without limitation, any vendor, materialman, customer, or supplier of the Seller, unless such acts or omissions are themselves caused by an event of Force Majeure as herein defined;

(iii)	any full or partial curtailment in the electric output of the Facility that is caused by or arises from a mechanical or equipment breakdown or other conditions attributable to normal wear and tear or defects, unless such mishap is caused by Force Majeure;

(iv)	changes in market conditions that affect the cost of the Seller’s supplies, or that otherwise render this Agreement uneconomic or unprofitable for the Seller;

(v)	the Seller’s inability to obtain Permits or approvals of any type for the construction, operation, or maintenance of the Facility;

ARTICLE 17

(vi)	the Seller’s inability to obtain sufficient geothermal resource or materials to operate the Expansion Facility;

(vii)	a Forced Outage except where such Forced Outage is caused by an event of Force Majeure;

(viii)	litigation or administrative or judicial action pertaining to this Agreement, the Site, the Expansion Facility, the Existing Facility, any Permits, or the design, construction, maintenance or operation of the Expansion Facility and/or Existing Facility; and

(ix)	any full or partial curtailment in either the ability of the Facility to deliver its Committed Capacity or in the ability of the Company to accept the Committed Capacity which is caused by any action or inaction of a third party, including but not limited to any vendor or supplier of the Seller or the Company, except to the extent due to Force Majeure.

17.2 Consequences of Force Majeure

A. Neither Party shall be responsible or liable for any delay or failure in its performance under this Agreement, nor shall any delay, failure, or other occurrence or event become an Event of Default, to the extent such delay, failure, occurrence or event is substantially caused by conditions or events of Force Majeure, provided that:

(1) The non-performing Party gives the other Party prompt written notice describing the particulars of the occurrence of Force Majeure;

(2) The suspension of performance is of no greater scope and of no longer duration than is required by Force Majeure;

(3) The non-performing Party proceeds with due diligence to remedy its inability to perform and provides weekly progress reports to the other Party describing actions taken to end or minimize the effects of the Force Majeure and the anticipated duration of the Force Majeure; and

(4) When the non-performing Party is able to resume performance of its obligations under this Agreement, that Party shall give the other Party written notice to that effect.

ARTICLE 17

100

B. The Party so excused shall make all reasonable efforts, including all reasonable expenditures of necessary funds, to cure, mitigate or remedy such Force Majeure event. Any payments due as compensation for the obligation so excused shall also be excused for so long as the obligation is not performed due to Force Majeure. The burden of proof shall be on the Party claiming Force Majeure pursuant to this Article 17.

C. Except as otherwise expressly provided for in this Agreement, the existence of a condition or event of Force Majeure shall not relieve the Parties of their obligations under this Agreement to the extent that performance of such obligations is not precluded by the condition or event of Force Majeure.

17.3 Effect of Force Majeure on Milestone Dates and Commercial Operation Date Deadline

During the occurrence of a Force Majeure event, each Condition Precedent in Section 2.3A and each Milestone Date in Attachment B, shall be extended on a Day-for-Day basis until the end of such Force Majeure event; provided, however, in no event shall Force Majeure extend any such Milestone Date beyond the Commercial Operation Date Deadline provided in Section 3.2A(3). In no event will any delay or failure to perform caused by any condition or event of Force Majeure extend this Agreement beyond its stated Term.

17.4 Right to Terminate Due to Force Majeure

Notwithstanding any other provision of this Agreement, if a Party is prevented from substantially performing its obligations under this Agreement by Force Majeure for a period of nine (9) consecutive months in the case of a single Force Majeure event or twelve (12) consecutive months in the case of more than one (1) Force Majeure event, the other Party may terminate the Agreement without further obligation or liability of either Party to the other hereunder. Such termination shall be effective upon thirty (30) Days written notice to the other Party prior to the resumption of substantial performance; provided, however, that if substantial performance is resumed during such thirty (30) Day period, such termination shall not be effective. The Party not claiming Force Majeure may, but shall not be obligated to, extend such periods for such additional time as it, at its sole discretion, deems appropriate, if the affected Party is exercising due diligence in its efforts to cure the conditions or events of Force Majeure.

17.5 Obligations Remaining After Event of Force Majeure

No monetary obligations of either Party which arose before the occurrence of an event of Force Majeure causing the suspension of performance shall be excused as a result of such occurrence.

ARTICLE 17

101

The obligation to pay in a timely manner any payments owed pursuant to Article 5 (Rates for Purchase), and any other money for obligations and liabilities which matured prior to the occurrence of an event of Force Majeure is absolute and shall not be subject to the Force Majeure provisions. In the event of a Seller Force Majeure which reduces or limits the Expansion Facility’s capability to deliver capacity and/or energy, the Company shall be obligated to pay for capacity only to the extent such capacity is made available by the Seller and for such reduced energy as it may accept. In the event of a Company Force Majeure which reduces or limits the Company’s capability to purchase energy, the Company shall pay for such reduced energy as it may accept, but shall remain obligated to pay for capacity to the extent made available by the Seller in accordance with this Agreement.

17.6 Delays Attributable to the Company

The Seller shall be excused from a failure to meet any specified Milestone Date where the Seller can establish that such a failure is solely attributable to any delay or failure by the Company obtaining any consents or approvals from governmental authorities or third parties required for the Company to perform its obligations under this Agreement (whether or not caused by any conditions or events of Force Majeure)(“Delay Conditions”), provided that for such a failure, the Milestone Date that is not met due to the Delay Condition(s), and any affected Milestone Dates that follow, shall be extended for a period of time equal to the period of time between (i) the Milestone Date that is not met due to the Delay Condition(s) and (ii) the Day that the Company has corrected the Delay Condition(s).

ARTICLE 17

102

ARTICLE 18 - ELECTRIC SERVICE SUPPLIED BY THE COMPANY

This Agreement does not provide for any electric services by the Company to the Seller. If the Seller requires any electric services from the Company, the Company shall provide such service on a non-discriminatory basis in accordance with the Company’s Schedule “J” tariff, a copy of which is attached as Attachment S, or successors thereof.

Such consent shall not be unreasonably withheld, delayed or conditioned; provided (i) at least thirty (30) Days prior notice of any such assignment shall be given to the other Party; and (ii) any assignee shall expressly assume the assignor’s obligations hereunder, unless otherwise agreed to by the other Party, and no assignment, whether or not consented to, shall relieve the assignor of its obligations hereunder if the assignee fails to perform, unless the other Party agrees in writing in advance to waive the assignor’s continuing obligations pursuant to this Agreement.

19.2 Assignment by the Company

This Agreement shall not be assignable by the Company without the prior written consent of the Seller (which consent shall not be unreasonably withheld, delayed or conditioned); provided that the Company shall have the right, without the consent of the Seller, to assign its interest in this Agreement to any affiliated company owned in whole or in part by Hawaiian Electric Industries, Inc., provided further that such assignment does not impair the ability of the Seller to continue to receive the payments it is entitled to under this Agreement and, further provided that the Company will remain directly responsible for any obligations under this Agreement that only the Company, as the public utility serving the Island of Hawaii, can carry out.

19.3 Binding on Assigns

This Agreement and all of its covenants, terms and provisions shall be binding upon and shall inure to the benefit of and be enforceable by the Parties and their respective successors and assigns.

The Seller will, in any such written notice to the Company, specify the terms and conditions, including any applicable deadlines and other matters that the Seller deems relevant, under which the Seller is willing to consider an offer to purchase the Facility from the Company. The Parties acknowledge that this provision does not create any legal or other obligation upon the Seller to sell the Facility or to offer the Facility for sale to the Company, and is only an expression of the Seller’s willingness, under the conditions stated above, to inform the Company if the Seller desires such sale.

Both Parties will extend commercially reasonable efforts to resist and appeal any PUC actions, decisions, or orders denying or having the effect of denying or otherwise preventing the Company from recovering any or all amounts paid to the Seller pursuant to the terms of the Agreement; provided that the Company shall reimburse the Seller for any and all reasonable out-of-pocket expenses incurred in assisting the Company in accordance with this Section 25.1.

All other information and documents furnished under this Agreement shall be furnished on a non-confidential basis.

25.14 PUC Approval

A. The Parties acknowledge and agree that this Agreement, and any amendments, supplements or related instruments thereto, is subject to approval by the PUC, and the Parties’ respective obligations herein are conditioned upon receipt of such approval, except as specifically provided otherwise herein. Upon execution of this Agreement, the Parties shall use good faith efforts to obtain, as soon as practicable, an order from the PUC that does not contain terms and conditions deemed to be unacceptable to either of the Parties, and is in a form deemed to be reasonable by the Parties, ordering that:

(1) this Agreement is approved;

(2) the purchased power costs (which costs include without limitation the Energy Charge payments and the Capacity Charge payments) to be incurred by the Company as a result of this Agreement are reasonable;

ARTICLE 25

114

(3) the Company’s purchased power arrangements under this Agreement, pursuant to which the Company will purchase energy and Firm Capacity from the Seller, are prudent and in the public interest;

(4) effective as of or prior to the date of the order, the purchased power costs (and applicable revenue taxes) and increases and decreases in the purchased power costs (and applicable revenue taxes) to be incurred by the Company pursuant to this Agreement may be included in the Company’s Energy Cost Adjustment Clause and Firm Capacity Surcharge, and/or Purchased Power Adjustment Clause (if applicable), during the Term of the Agreement; and

(5) the Company may include the purchased power costs (and applicable revenue taxes) incurred by the Company pursuant to this Agreement, including Capacity Charge payments and Energy Charge payments, in the Company’s revenue requirements for ratemaking purposes and for the purposes of determining the reasonableness of the Company’s rates during the Term.

This order is referred to herein as the “PUC Approval Order”.

B. The term “Final Non-appealable Order from the PUC” means a PUC Approval Order (i) that is considered to be final by HELCO, in its sole discretion, because HELCO is satisfied that no party to the subject Public Utilities Commission proceeding intends to seek a change in such PUC Approval Order through motion or appeal, or (ii) that is not subject to appeal to any Circuit Court of the State of Hawaii, Intermediate Court of Appeals of the State of Hawaii, or the Supreme Court of the State of Hawaii, because the period permitted for such an appeal (the “Appeal Period”) has passed without the filing of notice of such an appeal, or (iii) that was affirmed on appeal to any Circuit Court of the State of Hawaii, Intermediate Court of Appeals of the State of Hawaii, or the Supreme Court of the State of Hawaii, or was affirmed upon further appeal or appellate process, and that is not subject to further appeal, because the jurisdictional time permitted for such an appeal and/or further appellate process such as a motion for reconsideration or an application for writ of certiorari has passed without the filing of notice of such an appeal or the filing for further appellate process.

C. Notwithstanding any other provisions of this Agreement to the contrary, the Company’s obligations under this Agreement to purchase any power delivered by the Seller and to pay the Capacity Charge and/or Energy Charge, and any and all obligations of the Company which are ancillary to that purchase and those payments, are all contingent upon obtaining the Final Non-appealable Order from the PUC. Except as provided in Section 2.2A, in no event shall

ARTICLE 25

115

either Party become liable to the other for matters occurring under this Agreement prior to the PUC Approval Date.

D. Promptly after the issuance of a PUC Approval Order, the Company shall provide the Seller with a copy of such PUC Approval Order together with a written statement as to whether the conditions set forth in (i) Section 25.14A, and (ii) Section 25.14B(i) above have been satisfied.

E. As used in this Agreement, the term “PUC Approval Date” shall be defined as the date of issuance of the PUC Approval Order if the Company provides the written statement referred to in Section 25.14D to the effect that the condition referred to in clause (i) of the definition of Final Non-appealable Order from the PUC has been satisfied or in the absence of such a written statement:

(1) If a PUC Approval Order is issued and is not made subject to a motion for reconsideration filed with the PUC or an appeal, the PUC Approval Date shall be the date one Day after the expiration of the Appeal Period permitted for filing of an appeal following the issuance of the PUC Approval Order.

(2) If the PUC Approval Order became subject to a motion for reconsideration, and the motion for reconsideration is denied or the PUC Approval Order is affirmed after reconsideration, and such order is not made subject to an appeal, the PUC Approval Date shall be deemed to be the date one Day after the expiration of the Appeal Period permitted for filing of an appeal following the order denying reconsideration of or affirming the PUC Approval Order.

(3) If the PUC Approval Order, or an order denying reconsideration of the PUC Approval Order or affirming approval of the PUC Approval Order after reconsideration, becomes subject to an appeal, then the PUC Approval Date shall be the date upon which the PUC Approval Order becomes a non-appealable order within the meaning of the definition of a Final Non-appealable Order from the PUC.

DESCRIPTION OF MODIFICATIONS TO THE FACILITY

A. Modifications to the Facility. The Facility and/or Interconnection Facilities shall be modified prior to the Acceptance Test to the extent necessary to allow the following:

1. The Company is to have remote dispatch control of the Facility in the range of twenty-two (22) to thirty-eight (38) MW. In emergency situations the Seller may be required to reduce below the normal limits of the Current PPA as deemed necessary by the System Operator during abnormal operating conditions or emergencies, and/or as the result of the local equipment response to high frequency as defined in Section 3.2.C (2). The Company may curtail energy purchases from the Facility to twenty-two (22) MW off-peak for excess energy or system conditions. Remote dispatch control will be performed through a single interface for the Facility through the Company’s EMS and will participate in economic dispatch and supplemental frequency control under AGC.

2. The Facility will provide voltage regulation at the Point of Interconnection. The Seller shall replace the existing analog voltage controller with a digital DECS 200. The target voltage to be maintained at the Point of Interconnection will be specified by the Company’s System Operator by a remote signal from its EMS.

3. The Metering Point of the Facility is to be on the high side of the step up transformers at the Point of Interconnection. The Existing Facility will be metered by two (2) meters and the Expansion Facility will be separately metered.

4. The Existing Facility equipment will be modified to provide automatic reduction of power during high-frequency conditions. The organic cycle units will be modified to incorporate a tunable droop setting which shall be set according to HELCO’s request to coordinate with HELCO generating units (initially four percent (4%) without deadband). This setting shall be changed upon HELCO request as necessary for grid droop response coordination. Droop setting shall be as set forth in Section 3.2.C.(2). The Seller shall replace existing governors with digital units. The Existing Facility, along with the Expansion Facility, will provide three (3) MW quick load pick up during three (3)

A-4-1

seconds as an automated response to a drop in frequency when the output of the Facility is in the range of twenty-two (22) to thirty-five (35) MW. The existing Steam Turbines (eighteen (18) MW, one point eight (1.8) MW on each of ten (10) turbines) of the Existing Facility will provide an emergency frequency response to high frequency rather than a droop response. The emergency ramp-down will be achieved through steam bypass for the existing ten (10) steam turbines. The automated ramp down for high frequency will be provided by a controller at the Facility based on settable thresholds with settable time delays, a high frequency threshold, and an emergency high frequency threshold. The initial settings will be sixty and one-half (60.5) Hz with a time delay of ten (10) seconds and sixty-two (62) Hz with no time delay. When activated, the bypass will result in ramping. With the bypass feature, the Existing Facility will reduce power output automatically in response to high frequency up to fifty percent (50%) of steam turbine power or about ten (10) MW. Return from the high-frequency ramp is to be initiated after coordination with the Company’s System Operator.

5. For the Facility, all 13.8 kV bus voltages shall use voltage transducers with +/- 0.10% accuracy.

6. The Facility will remain connected through off-normal voltages and frequencies as within the capabilities of the Facility, however, the Seller shall install all necessary equipment such that the Facility must meet the minimum requirements set forth in Section 3.2C (Delivery of Power to the Company).

7. The Seller shall add a fourth condensate pump and add second (parallel) injection control valve as shown on the single line diagram attached as Exhibit 1 to Attachment A-4.

B. The Seller shall be responsible for all costs associated in any way with the modification of the Existing Facility and existing Interconnection Facilities.

C. The Seller shall be responsible for one hundred percent (100%) of the maintenance costs associated with the Facility and/or any upgrade of existing Interconnection Facilities.

D. The Seller shall be responsible for obtaining all permits, licenses, approvals and any other requirements required for the Seller to make the modifications to the Existing Facility.

E. Within sixty (60) Days of the Execution Date, a final (1) a single-line diagram, (2) relay list, and (3) trip scheme of

CERTAIN DEFINITIONS DERIVED FROM NERC GADS

The availability statistics are used in this Agreement to track the Available Capacity relative to the Firm Capacity in excess of thirty (30) MW (i.e., that portion of the Available Capacity provided by the Expansion Facility under this Agreement). Capacity cannot be measured on the basis of energy delivery as energy is controlled by the Company Dispatch and is not necessarily equal to the Available Capacity. Further, capacity payments and penalties associated with production of thirty (30) MW or less are addressed within the Current PPA.

Availability is based upon the Firm Capacity

The basis for the methodology are the definitions of EAF and EFOR in 2010 NERC GADS. However, due to the fact that availability statistics for this Agreement are for a portion of the total combined export of the Existing Facility and Expansion Facility, some modification of NERC GADS was required. Where there is no definition provided here, the unmodified 2010 NERC GADS methodology and definitions should be utilized. For example, the determination as to whether outages and derations are considered Forced Outages and derations versus Planned Outages and derations shall be made in accordance with the NERC GADS guidelines.

(AH) Available Hours - The equivalent of SH.

(SH) Service Hours – The total number of hours that the Available Capacity of the Facility is greater than thirty (30) MW for that reporting period.

(FOH) Forced Outage Hours – The sum of all hours when the Available Capacity is greater than thirty (30) MW but less than the Firm Capacity due to Forced Outages (U1, U2, U3) and/or Startup Failures (SF), excluding hours where the Forced Outage and/or Startup Failure is the result of conditions identified as excluded from EAF and EFOR calculations in Sections 3.2.B.(3), 3.2.D, and 4.2 B.

(EFDH) Equivalent Forced Derated Hours - The sum of all hours when the Available Capacity is greater than thirty (30) MW but less than the Firm Capacity due to Forced Derating(s) (D1, D2, D3), excluding hours where the Forced Outage and/or Startup Failure is the result of conditions identified as excluded from EAF and EFOR calculations in Sections 3.2B(3), 3.2D, and 4.2B. The time period of the deration is transformed into equivalent full outage hour(s) by multiplying the actual duration of the derating (hours) by the size of the

C-1-1

reduction (in MW) and dividing by the (Firm Capacity minus thirty (30)). The size of the reduction is equal to the Firm Capacity minus the Available Capacity. These equivalent hour(s) are then summed.

EFDH = Forced Derating Hours x (Size of Reduction)

(Firm Capacity–30)

(EPDH) Equivalent Planned Derated Hours - The sum of all hours when the Available Capacity is greater than thirty (30) MW but less than the Firm Capacity due to Planned Derating(s) (PD, DE), excluding hours where Planned Derating is the result of conditions identified as excluded from EAF and EFOR calculations in Sections 3.2B(3), 3.2D, and 4.2B. The time period of the deration is transformed into equivalent full outage hour(s). This is calculated by multiplying the actual duration of the derating (hours) by the size of the reduction (in MW) and dividing by the (Firm Capacity minus thirty (30)). The size of the reduction is equal to the Firm Capacity minus the Available Capacity. These equivalent hour(s) are then summed.

EPDH = (Planned Derating Hours x (Size of Reduction))

(Firm Capacity–30)

(EUDH) Equivalent Unplanned Derated Hours - The sum of all hours when the Available Capacity is greater than thirty (30) MW but less than the Firm Capacity due to Unplanned Deratings (D1, D2, D3, D4, DE), excluding hours where the Unplanned Derating is the result of conditions identified as excluded from EAF and EFOR calculations in Sections 3.2B(3), 3.2D, and 4.2B. The time period of the deration is transformed into equivalent full outage hour(s). This is calculated by multiplying the actual duration of the derating (hours) by the size of the reduction (MW) and dividing by the difference between the (Firm Capacity minus thirty (30)). The size of the reduction is the Firm Capacity minus the Available Capacity. These equivalent hour(s) are then summed.

EUDH = Unplanned Derating Hours x (Size of Reduction)

(Firm Capacity–30)

(PH) Period Hours – The number of hours that the Expansion Facility was in the active state for that reporting period.

C-1-2

(EAF) Equivalent Availability Factor – Calculated in accordance with the formula, terms and concepts defined by NERC GADS, but with the terms modified as defined in this Agreement. EAF in NERC GADS has been reduced since Equivalent Seasonal Derating Hours will be considered zero and is defined as follows:

EAF = AH - EPDH - EUDH x 100%

(EFOR) Equivalent Forced Outage Rate – Calculated in accordance with the formula, terms and concepts defined by NERC GADS with the terms modified as defined in this Agreement. EFOR shall be defined as follows

EFOR = FOH + EFDH x 100%

FOH + SH
