Reference:Exigent Circumstances Filing to Address Prospectively a Gas Pricing Logic Alignment Issue Affecting the 2017-2021 Installed Capacity Demand Curves

On October 16, 2020, New York Independent System Operator, Inc. (NYISO) filed revisions to its Market Administration and Control Area Services Tariff (Services Tariff) to address prospectively a gas pricing alignment logic issue that NYISO recently determined was incorporated into the currently effective installed capacity (ICAP) demand curves.[1] You state that NYISO relied on gas price data that it assumed represented the “trade day” price (the day before the delivery day) when in reality the data represented the “flow day” (the delivery day), and that NYISO therefore unnecessarily adjusted gas price data forward one day. You state that the gas pricing logic is embedded in currently effective models approved by the Commission. You further state that NYISO believes the alignment issue should be addressed prospectively for the upcoming 2020/2021 winter period through the instant filing. You also state that the NYISO Board of Directors directed NYISO to make this filing following NYISO’s exigent circumstances procedures because it is the most expeditious and effective way to address the alignment issue for the upcoming 2020/2021 winter period.

This filing proposes revisions to Sections 5.11 and 5.14 of the Services Tariff. On January 23, 2020, the Commission accepted tariff revisions to Services Tariff Sections 5.11 and 5.14 that were submitted in Docket No. ER19-2276-000. The NYISO submits as Attachment V to this filing a clean copy of the tariff revisions proposed herewith to incorporate the language into a version that will become effective on March 1, 2021, consistent with the Commission’s January 23, 2020 Order in Docket No. ER19-2276-000.

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 October 21, 2020, and March 1, 2021, as requested.
