Reference: Small Generator Interconnection Agreement, Service Agreement No. 2555

On September 24, 2020, New York Independent System Operator, Inc. (NYISO) and Niagara Mohawk Power Corporation (Niagara Mohawk) (together, Joint Filing Parties) submitted for filing an executed Small Generator Interconnection Agreement (SGIA) between NYISO, Niagara Mohawk, and Hecate Energy Albany 2 LLC (Hecate) to facilitate the interconnection of Hecate’s 20 MW Albany County 2 Solar Project to the New York State Transmission System.[1] Joint Filing Parties state that the SGIA contains non-conforming language compared to the language contained in the pro forma SGIA in Attachment Z of the NYISO Open Access Transmission Tariff (OATT). Specifically, Joint Filing Parties state that Attachment 5 and Section 1.3.1 of the SGIA has been modified to provide that NYISO’s provision of Capacity Resource Interconnection Service is subject to the requirements that if System Deliverability Upgrades are identified in the Class Year Study, and Hecate accepts its cost allocation for such System Deliverability Upgrades, the SGIA will be amended to incorporate the results of the Class Year Study. In addition, Attachment 5 provides that Hecate may not supply Unforced Capacity to the New York Control Area from the Facility until it has complied with the deliverability requirements set forth in Attachment S of the OATT, including the posting of associated security or payments. Further, Niagara Mohawk and Hecate have agreed that Hecate will be responsible for constructing certain Connecting Transmission Owner’s Interconnection Facilities associated with the Facility. Accordingly, the parties agreed to modify Section 1.5.3 of the SGIA to clarify that the Interconnection Customer, Hecate, can construct Connecting Transmission Owner’s Interconnection Facilities with the agreement of all parties.

Pursuant to the authority delegated to the Director, Division of Electric Power Regulation – East, under 18 C.F.R. § 375.307, your submittal is accepted for filing, effective September 14, 2020, as requested.

The filing was noticed on September 24, 2020, with comments, interventions, and protests due on or before October 15, 2020. Pursuant to Rule 214 (18 C.F.R. § 385.214), to the extent that any timely filed motions to intervene and any motion to intervene out-of-time were filed before the issuance date of this order, such interventions are granted. Granting late interventions at this stage of the proceeding will not disrupt the proceeding or place additional burdens on existing parties.

This acceptance for filing shall not be construed as constituting approval of the referenced filing or of any rate, charge, classification, or any rule, regulation, or practice affecting such rate or service contained in your filing; nor shall such acceptance be deemed as recognition of any claimed contractual right or obligation associated therewith; and such acceptance is without prejudice to any findings or orders that have been or may hereafter be made by the Commission in any proceeding now pending or hereafter instituted by or against NYISO or Niagara Mohawk.

This order constitutes final agency action. Requests for rehearing by the Commission may be filed within 30 days of the date of issuance of this order, pursuant to 18 C.F.R. § 385.713.
