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 10, 2021 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, 2022 to April 30, 2023 Capability Year at 19.6%. This decision was based on the NYSRC study, “New York Control Area Installed Capacity Requirement for the Period May 2022 to April 2023.” The study report can be found at NYSRC NYCA ICR Reports.

Draft Reliability Rules Posted for Review and Comment:

Approved New Rules:

Reliability Rule #149
RR #149 4-8-22
Reliability Rule Revision - RR 149 Clarify the Interpretation of the LOLE Reliability Risk Metric in the NYSRC Resource Adequacy Criterion and the Application of Multiple Reliability Risk Metrics in IRM and Resource Adequacy Assessments

This rule change has two components: (1) To express the NYSRC’s LOLE criterion’s quantification of resource adequacy in terms of “loss of load event-days per year” instead of “days per year,” in order to avoid a possible misinterpretation that the NYSRC ‘s LOLE criterion allows a loss of load duration of 2.4 hours per year, and (2) to require IRM and resource adequacy assessments to include multiple reliability risk metrics in order to more fully describe loss of load events.

The proposed LOLE criterion change is consistent with recommendations in the IEEE Resource Adequacy WG ‘s paper, Clarifying the Interpretation and Use of the LOLE Resource Adequacy Metric, presented at NERC’s Probabilistic Analysis Forum on October 5, 2021. This change would not affect in any way present ICS and NYISO procedures and models for IRM and resource adequacy assessments -- it brings the resource adequacy criterion in line with present study applications and criterion interpretations.
