Reference:Proposed Tariff Amendments to Open Access Transmission Tariff Rate Schedule 1 for Ramapo Phase Angle Regulator Cost Recovery

Dear Mr. Sweeney:

On June 21, 2017, as amended on August 11, 2017, the New York Independent System Operator, Inc. (NYISO) filed proposed amendments to Rate Schedule 1 of the NYISO Open Access Transmission Tariff. You state that the revisions will require NYISO Transmission Customers, on a going-forward basis, to pay up to one hundred percent of Consolidated Edison Co. of New York’s (Con Edison) cost of owning, maintaining, and operating two phase angle regulators (PARs) at the Ramapo Substation.[1] You also state that the proposed revisions are necessary to facilitate Con Edison’s installation of a replacement PAR at the Ramapo Substation. On August 11, 2017, NYISO submitted an errata filing to fill in two placeholders that NYISO intended to replace with references to the proposed July 1, 2017 effective date.[2] You state that this errata filing replaces the placeholder text with the requested July 1, 2017 effective date in the proposed revisions.
