Common use of Scope of Definitive Interconnection System Impact Study Clause in Contracts

Scope of Definitive Interconnection System Impact Study. (DISIS) The Definitive Interconnection System Impact Study shall evaluate the impact of the proposed Interconnection Requests in the Cluster on the reliability of the Utility’s System. The DISIS will consider the Utility’s Base Case as well as all Generating Facilities (and with respect to iii below, any identified Network Upgrades associated with such higher queued requests) that, on the date the DISIS Request Window closes: (i) are existing and directly interconnected to the Utility’s System; (ii) are existing and interconnected to Affected Systems and may have an impact on the Interconnection Request; and (iii) have a pending Interconnection Request to interconnect to the Utility’s System with a higher Queue Position than the DISIS Cluster, either individually under Section 1.10.1 or included in a higher queued Cluster Study. As set forth in Section 4.4.7, the DISIS is a phased study in which Phase 1 consists of a power flow and voltage analysis that is followed in Phase 2by a short circuit analysis and a stability analysis. Any DISISre-studies (Phase 3) shall consist of a power flow/voltage analysis, a short circuit analysis, and/or a stability analysis, as needed. The DISIS report shall state the assumptions upon which it is based; state the results of the analyses; and provide the requirements or potential impediments to providing the requested interconnections, including a preliminary indication of the cost and length of time that would be necessary to correct any problems identified in those analyses and to implement the interconnections. The DISIS report shall provide a list of facilities that are required as a result of the Interconnection Requests and a non-binding good faith Preliminary Estimated Upgrade Charge estimate of cost responsibility and a nonbinding good faith estimated time to construct. For purposes of clustering Interconnection Requests, the Utility may make reasonable changes to the requested Point(s) of Interconnection as part of the DISIS to facilitate the efficient and reliable interconnection of Interconnection Customers at common Points of Interconnection. The Utility shall notify Interconnection Customers in writing of any intended changes to the requested Point(s) of Interconnection, and the Point(s) of Interconnection shall only change upon mutual agreement. Where the Interconnection Customer agrees to a Utility’s proposed change to the Point of Interconnection, and the change results in a loss of site control, the Interconnection Customer shall have 150 days to provide affirmation and reasonable documentation, if requested by the Utility, that site control to the new Point of Interconnection has been obtained, or the Interconnection Customer shall be required to post the additional financial security required by Section 4.4.11 to continue to proceed through the Definitive Interconnection Study process. Where an Interconnection Customer is proposing to interconnect a Generating Facility to the Utility’s Distribution System and is determined through Phase 1 not to cause or contribute to the need for Network Upgrades requiring further study in Phase 2, the Utility shall complete a distribution level System Impact Study for that Interconnection Customer, as discussed in Section 4.4.7.1.

Scope of Definitive Interconnection System Impact Study. (DISIS) The Definitive Interconnection System Impact Study shall evaluate the impact of the proposed Interconnection Requests in interconnection(s) within the Cluster on the reliability of the Utility’s Transmission System. The DISIS Definitive Interconnection System Impact Study will consider the UtilityTransmission Provider’s Base Case as well as all Generating Facilities (and with respect to iii (iii) below, any identified Network Upgrades associated with such higher queued requests) that, on the date the DISIS Request Window closes: (i) are existing and directly interconnected to the Utility’s Transmission System; (ii) are existing and interconnected to Affected Systems and may have an impact on the Interconnection Request; and (iii) have a pending Interconnection Request to interconnect to the Utility’s Transmission System with a higher Queue Position queue position than the DISIS Cluster, either individually under Section 1.10.1 5.2 or included in a higher queued Cluster Study; and (iv) have executed an LGIA or requested that an unexecuted LGIA be filed with FERC. As set forth in more detail in Section 4.4.710.8 below, the DISIS Definitive Interconnection System Impact Study is a phased study in under which the first phase (Phase 1 1) consists of a power flow and voltage analysis that is followed in by a second phase (Phase 2by 2) that consists of a short circuit analysis and a stability analysis. Any DISISreDISIS re-studies (Phase 3) shall consist of a power flow/voltage analysis, a short circuit analysis, and/or a stability analysis, as needed. The DISIS Definitive Interconnection System Impact Study report shall state the assumptions upon which it is based; state the results of the analyses; and provide the requirements or potential impediments to providing the requested interconnectionsinterconnection, including a preliminary indication of the cost and length of time that would be necessary to correct any problems identified in those analyses and to implement the interconnectionsinterconnection. The DISIS report Definitive Interconnection System Impact Study shall provide a list of facilities that are required as a result of the Interconnection Requests Request and a non-binding good faith Preliminary Estimated Upgrade Charge estimate of cost responsibility and a nonbinding good faith estimated time to construct. For purposes of clustering Interconnection Requests, the Utility Transmission Provider may make reasonable changes to the requested Point(s) of Interconnection as part of the DISIS to facilitate the efficient and reliable interconnection of Interconnection Customers at common Points of Interconnection. The Utility Transmission Provider shall notify Interconnection Customers in writing of any intended changes to the requested Point(s) of Interconnection, Interconnection and the Point(s) of Interconnection shall only change upon mutual agreement. Where the Interconnection Customer agrees to a UtilityTransmission Provider’s proposed proposal to change to the Point of Interconnection, Interconnection and the change results in a loss of site controlSite Control, the Interconnection Customer shall have 150 days to provide affirmation and reasonable documentation, if requested by the UtilityTransmission Provider, that site control Site Control to the new Point of Interconnection has been obtained, obtained or the Interconnection Customer shall be required to post the additional financial security required by Section 4.4.11 10.11.6 to continue to proceed through the Definitive Interconnection Study process. Where an Interconnection Customer is proposing to interconnect a Generating Facility to the Utility’s Distribution System and is has been determined through Phase 1 not to cause or contribute to the need for Network Upgrades requiring further study in Phase 2, the Utility Transmission Provider shall complete a distribution Distribution level System Impact Study for that Interconnection CustomerStudy, as further discussed in Section 4.4.7.110.8(a.) below.
