About New York State Reliability Council

The New York State Reliability Council, L.L.C. ("NYSRC") is a not-for-profit entity, organized as a Delaware limited liability company, whose mission is to promote and preserve the reliability of electric service on the New York State Power System by developing, maintaining, and, from time-to-time, updating the Reliability Rules which shall be complied with by the New York Independent System Operator ("NYISO") and all entities engaging in electric transmission, ancillary services, energy and power transactions on the New York State Power System. The NYSRC shall carry out its mission with no intent to advantage or disadvantage any Market Participant's commercial interests.

The NYSRC's mission also includes monitoring compliance with the Reliability Rules by working in consultation with the NYISO to assure compliance, including when necessary, seeking compliance through the dispute resolution procedure contained in the ISO/NYSRC Agreement, and taking such other actions which may be necessary to carry out the purpose of the NYSRC Agreement.

The NYSRC is governed by the NYSRC Executive Committee comprised of thirteen (13) members consisting of representatives from the six (6) current Transmission Owners - Central Hudson Gas & Electric Corporation, Consolidated Edison Company of New York, Inc., Long Island Power Authority, National Grid, USA, New York State Electric & Gas Corporation/Rochester Gas & Electric Corporation, and the Power Authority of the State of New York; one (1) representative of the Wholesale Sellers sector - Independent Power Producers of New York, Inc.; one (1) representative of the Large Consumers sector - Multiple Intervenors; one (1) representative of the Municipals and Electric Cooperatives sector- New York Municipal Power Agency; and four (4) members not affiliated with any Market Participants.

At its December 6, 2019 meeting, the Executive Committee of the New York State Reliability Council set the New York Control Area (NYCA) Installed Reserve Margin (IRM) requirement for the May 1, 2020 to April 30, 2021 Capability Year at 18.9%. This decision was based on the NYSRC study, “New York Control Area Installed Capacity Requirement for the Period May 2020 to April 2021.” The study report can be found at NYSRC NYCA ICR Reports.

Draft Reliability Rules Posted for Review and Comment:

PRR#128 4-30-20
Proposed Revised Reliability Rule - PRR128 Definition of  New York State Bulk Power System (NYS Bulk Power System)
The existing legacy definition of the NYS Bulk Power System requires an update due to NPCC modifications to its Document A-10 "Classification of Bulk Power System Elements" which provides the methodology to identify the Bulk Power System (BPS) Elements, or parts thereof, of the interconnected NPCC Region.  NPCC Criteria and Directories, which establish more stringent requirements than the NERC Standards, are applicable to the BPS. New York is part of the NPCC Region.

Approved New Rules:

RR#148 3-19-20
Proposed Reliability Rule Revsion - PRR 148  Mitigation of Major Emergencies
Under current NYSRC reliability rules, the NYISO is required to declare a Major Emergency immediately if the post-contingency loading of an interface exceeds the stability or voltage collapse limits by greater than 5%. Recent events have demonstrated that exceedances meeting this criterion can in some circumstances pose little immediate threat to reliability and can be easily resolved through application of normal NYISO procedures.

PRR #148 3-19-20

RR 146 4-30-20
New Reliability Rule -- NYISO Interconnection requirement studies shall include, as applicable, special studies to examine the impacts of dynamically active technologies.
Studies associated with the interconnection of dynamically active transmission devices have been included in the NYISO's interconnection process and periodic transmission planning/operating studies on an ad-hoc basis. Based on the proliferation of inverter-based resources, as well as applications of active-series/shunt compensation and HVDC connections to the NYCA system, it is proposed to include a requirement for special studies in the NYSRC Reliability Rules.
