Dear Mr. Galaburda:

Niagara Mohawk Power Corporation’s (Niagara Mohawk) submittal is accepted for filing, effective January 27, 2011 as requested.[1]

On February 18, 2011, you filed, on behalf of Niagara Mohawk, a revised Interconnection Agreement (IA) between Niagara Mohawk and United States Gypsum Company (U.S. Gypsum) under the New York Independent System Operator, Inc.’s (NYISO) NYISO Agreements tariff.  You state that the original IA expired during its own terms in January 2011 and that under the revised IA, Niagara Mohawk will continue to provide interconnection service for an additional ten years to U.S. Gypsum’s 5 MW generating facility located in Oakfield, New York.

The filing was noticed on February 18, 2011, with comments due on or before March 11, 2011.  Pursuant to Rule 214 (18 C.F.R. § 385.214 (2010)), all timely filed motions to intervene and any motion to intervene out-of-time filed before the issuance date of this order are granted.  Granting late intervention at this stage of the proceeding will not disrupt the proceeding or place additional burdens on existing parties.  No protests or adverse comments were filed.

This action is taken pursuant to the authority delegated to the Director, Division of Electric Power Regulation – East, under 18 C.F.R. § 375.307.

This acceptance for filing shall not be construed as constituting approval of any service, rate, charge, classification, or any rule, regulation, or practice affecting such rate or service provided for in the filed documents; nor shall such action be deemed as recognition of any claimed contractual right or obligation affecting or relating to such service or rate; and such acceptance is without prejudice to any finding or orders which have been or may hereafter be made by the Commission in any proceeding now pending or hereafter instituted by or against 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.

Sincerely,

Jignasa Gadani, Director

Division of Electric Power Regulation – East
