Reference:Tariff Revisions Regarding Energy Storage Resource Participation Model

On April 30, 2020, the New York Independent System Operator, Inc. (NYISO) filed revisions to its Market Administration and Control Area Services Tariff (Services Tariff) to enhance its Energy Storage Resource (ESR) participation model.[1]  NYISO states that the proposed tariff revisions are the result of its continued efforts to integrate ESRs in NYISO’s Energy, Ancillary Services and Capacity Markets, and will modify the rules recently accepted by the Commission in Docket No. ER19-467-000.[2]  Specifically, NYSO states that the proposed tariff revisions will:  (i) clarify the formulae used to calculate Day-Ahead Margin Assurance Payments for ESRs; (ii) modify NYISO’s method for setting feasible Day-Ahead and Real-Time schedules; (iii) modify the market mitigation measures related to ESR offer caps, mitigation rules, and reference levels; (iv) refine the Day-Ahead Market bidding obligations for ESRs that are Installed Capacity Suppliers; and (v) enable NYISO to proactively address possible Day-Ahead Market scheduling concerns related to ESRs’ use of ISO-Managed Energy Levels.

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, as requested.  NYISO requests a flexible effective date of no later than September 30, 2020 and proposes to submit a compliance filing at least two weeks prior to the proposed effective date, specifying the date on which all the tariff revisions will become effective.

The filing was noticed on April 30, 2020, with comments, interventions, and protests due on or before May 21, 2020.  Pursuant to Rule 214 (18 C.F.R. § 385.214), 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.
