Reference:Service Agreement No. 2549

On August 26, 2020, New York Independent System Operator, Inc. (NYISO) and Niagara Mohawk Power Corporation d/b/a National Grid (Niagara Mohawk) jointly filed an executed Small Generator Interconnection Agreement (SGIA) among NYISO, Niagara Mohawk, and Duke Energy Renewables Solar, LLC (Duke) under NYISO’s Open Access Transmission Tariff.[1] The filing states that Duke is constructing a 15 MW solar-powered facility (Facility) located in the town of Boonville in Lewis County, New York and that the Facility will interconnect to the New York State transmission system at Niagara Mohawk’s 46kV bus at its Boonville Station. The filing further states that the SGIA contains language that does not conform to the language in the Pro Forma SGIA contained in Attachment Z of the NYISO OATT, because Duke may construct Niagara Mohawk’s interconnection facilities associated with the Facility if all parties agree.
