Company, a California partnership, hereinafter referred to as "HGC" and Southern
California Edison Company, a California corporation, hereinafter referred to as
"Edison," hereinafter sometimes referred to individually as "Party" and
collectively as "Parties."
2. RECITALS
This Amendment No. 1 is made with reference to the following facts,
among others:
2.1 On August 26, 1983, Edison and Chevron U.S.A Inc. executed the
Power Purchase and Sales Agreement to provide the terms and conditions for the
sale by Chevron and purchase by Edison of capacity and energy delivered to the
Point of Interconnection from a 47 MW (net) electrical generating facility
located at Heber, California utilizing geothermal steam as the prime mover
energy source.
2.2 On August 26, 1983, Chevron assigned and HGC assumed Chevron's
right, title and interest in the Power Purchase and Sales Agreement between
Chevron and Edison, dated August 26, 1983.
2.3 On March 16, 1984, Chevron and HGC issued a Notice of Intention to
Proceed to Edison. The Notice of Intention to Proceed stated Chevron and HGC's
desire to construct the facilities necessary to proceed with the Power Purchase
and Sales Agreement, dated August 26, 1983.
2.4 The Public Utilities Commission of the State of California has
issued Decision No. 00-00-000, which authorized the long-term power-purchase
contract, to be known as Standard Offer No. 4, which established the terms and
conditions of the sale of power produced by Qualifying Facilities and the
purchase by Edison of electrical energy therefrom.
2.5 The Parties wish to provide definitive terms for the exercise of
Seller's option to deliver Net Energy to the Point of Interconnection pursuant
to the terms of Section 34.3 of the Power-Purchase and Sales Agreement by
electing to pay for the upgrade of Edison's 115/92 kV substation facility and
agreeing to pay the flat monthly transmission service cost, as specified in
Section 34.3 of the Power-Purchase and Sales Agreement, commencing on August 1,
1985.
2.6 The Parties, therefore, desire to amend the Agreement to modify the
provisions covering (i) payments by Edison for energy, (ii) payments by Edison
for capacity and (iii) transmission cost to be paid by HGC as Seller.
3. Agreement: The Parties agree to amend the Power Purchase and Sales
Agreement as follows:

hours (35 days) in any 12-month period. This allowance may be used in increments
of an hour or longer on a consecutive or nonconsecutive basis.
15.3.2 Seller may accumulate unused maintenance hours on a year-to-year
basis up to a maximum of 1,080 hours (45 days). This accrued time must be used
only for major overhauls, as such major overhauls are reasonably defined by the
Seller.
15.4 Failure to Meet Minimum Performance Requirements
15.4.1 Except when caused by uncontrollable forces, if Seller fails to
meet the minimum performance requirements as set forth in Section 15.2.2.2. The
following shall apply:
15.4.1.1 Seller may be placed on probation for a period not to exceed
15 months or as otherwise agreed to by the Parties. During this period, the
monthly capacity payment will be based on the level of Capacity actually made
available as calculated in Section 15.2.2.1.
15.4.1.2 If Seller meets or demonstrates to Edison pursuant to Section
12.2 that it can meet its minimum requirement during the probationary period,
Edison shall reinstate regular capacity payments.
15.4.1.3 If Seller fails to meet its minimum requirements during the
probationary period Edison may derate the Capacity to the greater of the
Capacity actually made available when the minimum requirements stated in Section
15.2.2.2 were not met, or the Capacity at which Seller is reasonably likely to
meet the minimum
11
requirements. In either case, the quantity by which the Capacity is reduced
shall be Considered terminated without prescribed notice as provided in Section
4.4.
15.4.2 If Seller is prevented from meeting the minimum performance
requirement because of a schedule outage, a Forced Outage or an Emergency on the
Edison electric system, Edison shall continue to make capacity payments to
Seller. Under Option B, the calculations of capacity payments will treat hours
of Forced Outage and Emergency on the Edison system the same as scheduled
maintenance outages.
15.4.3 If deliveries are interrupted or reduced because of
uncontrollable forces, Edison shall continue to make capacity payments to Seller
for 90 days from the occurrence of the uncontrolled force event. Under Option B,
the calculation of capacity payments will treat hours of interruption or
reduction by reason of an uncontrollable force, the same as scheduled
maintenance outages with reductions in Capacity treated on a pro rata basis.
8. Amendment to Section 34:
Section 34 is deleted in its entirety and replaced with the following:
34.1 Edison, with Seller's assistance, shall seek to contract with
Interconnecting Utility and/or third parties in order to secure the most
economic transmission path and service costs for the delivery of Net Energy from
the Project to the Point of Interconnection during the Contract Term at terms
and conditions acceptable to Seller. Seller shall be responsible for all costs
including transmission losses, incurred in the delivery of the Net Energy from
the Project to the Point of Interconnection.
12
The exact, mutually agreed-upon transmission service cost shall be established
prior to the Date of Firm Operation and may be adjusted periodically as
necessary. The transmission service payments shall consist of (i) a flat monthly
service charge expressed in dollars per kilowatt per month and (ii) transmission
losses expressed in percentage of Net Energy lost in the transmission of Net
Energy from the Project to the Point of Interconnection.
34.2 Notwithstanding Section 34.1, for the first five years of the
Contract Term, the Seller shall pay for the transmission of the Net Energy from
the Project to the Point of Interconnection at a transmission service cost based
on a method of transmission comparable to the method which is then in use or
would be negotiated for Edison's geothermal facilities at Brawley and Salton Sea
utilizing transmission facilities in existence at that point in time.
Power-exchange arrangements which are in effect or might be in effect for the
transmission of the energy generated at Edison's geothermal facilities at
Brawley and Salton Sea will apply to the provisions of this Section 34.2 only to
the extent there is uncommitted capacity available in such exchange arrangements
at the date of Firm Operation. The provisions of this Section 34.2 are subject
to the following conditions:
34.2.1 The date of initial delivery of Net Energy shall occur on or
before August 1, 1985. If Seller does not deliver Net Energy to the Point of
