Reference: Joint Filing of an Executed Transmission Project Interconnection Agreement Among the New York Independent System Operator, Inc., Niagara Mohawk Power Corporation d/b/a National Grid, and LS Power Grid New York Corporation I

On April 15, 2021, New York Independent System Operator, Inc. (NYISO) and Niagara Mohawk Power Corporation d/b/a National Grid (National Grid) (together, Joint Filing Parties) filed an executed Transmission Project Interconnection Agreement entered into by the NYISO, National Grid, and LS Power Grid New York Corporation I (LS Power), labeled as Service Agreement No. 2612 under the NYISO’s Open Access Transmission Tariff (OATT).[1]  As part of the NYISO’s Public Policy Transmission Planning Process, the New York Public Service Commission identified a need to increase Central East transfer capability in New York by at least 350 MW (Segment A) and UPNY/SENY transfer capability in New York by at least 900 MW (Segment B) to provide additional capability to move power from upstate to downstate New York.  On April 8, 2019, the NYISO selected the proposal that was submitted by North American Transmission (now LS Power) and the New York Power Authority (NYPA) as the more efficient or cost-effective transmission solution to address Segment A.  NYISO requested that the revisions be accepted effective April 2, 2021.[2]

Pursuant to the authority delegated to the Director, Division of Electric Power Regulation – East, under 18 C.F.R. § 375.307 (2020), your submittal is accepted for filing,               effective April 2, 2021, as requested.

The filing was noticed on April 15, 2021, with comments, interventions, and protests due on or before May 6, 2021. Pursuant to Rule 214 (18 C.F.R. § 385.214 (2020)), 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.

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 (2020).
