Reference: Compliance Filing Establishing Effective Date for Transmission Shortage Costs

Dear Mr. Sweeney:

On January 28, 2016, the New York Independent System Operator, Inc. (NYISO) filed proposed tariff amendments to its Market Administration and Control Area Services Tariff (Services Tariff) and its Open Access Transmission Tariff (OATT) to specify the effective date for its Transmission Shortage Cost pricing methodology.[1]  The provisions set forth a graduated transmission demand curve, which revise the maximum shadow prices used to resolve transmission constraint shortages.  Originally, NYISO requested a flexible effective date for its proposed tariff revisions. NYISO’s proposal was accepted for filing, subject to NYISO making a compliance filing with revised tariff records no later than 14 days prior to the date on which its graduated transmission demand curve will be operational reflecting the effective date of the tariff provisions.[2]  NYISO states that it expects to fully implement the accepted revisions for the February 11, 2016 market day and proposes revised tariff records with that effective date.

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 February 11, 2016, as requested.

The filing was noticed on January 29, 2016, with comments, interventions, and protests due on or before February 18, 2016. Pursuant to Rule 214 (18 C.F.R. 385.214 (2015)), 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 which 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.

Sincerely,

Kurt M. Longo, Director
