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 9, 2022 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, 2023 to April 30, 2024 Capability Year at 20.0%. This decision was based on the NYSRC study, “New York Control Area Installed Capacity Requirement for the Period May 2023 to April 2024.” The study report can be found at NYSRC NYCA ICR Reports.

Draft Reliability Rules Posted for Review and Comment:

Posted for 45-Day Comment Period -- Proposed Reliability Rule (PRR) #151 -- Large Inverter Based Resources (IBR)

New Proposed Reliability Rule -- PRR 151 -- Establishes minimum interconnection standards in the New York Control Area (NYCA) for Large Inverter Based Resources (IBR) Generating Facilities based on IEEE Standard 2800-2022.  The proposed new Reliability Rule was approved for posting by the NYSRC Executive Committee on March 10, 2023.  We look forward to receiving stakeholder comments.

Need for new rule: The New York Independent System Operator (NYISO) Interconnection Queue as of 1/5/23 has greater than 50,000 MW's of Large Facility (>20MW) Inverter Based Resources.  The New York State Reliability Council (NYSRC) does not presently have specific IBR interconnection criteria in its Reliability Rules.  PRR 151, when implemented, will be applicable to all NYISO interconnection studies involving IBRs for inverter based projects 20MW or greater beginning in the next Class Year after the completion of the upcoming Class Year 2023.

This proposal is based upon: (1) recent disturbances in Texas and California where IBRs failed to perform reliably creating system supply deficits; (2) the cumulative expected magnitude of IBRs in the NYCA per New York State's Climate Leadership & Community Protection Act (CLCPA) mandates; (3) NERC's recommendation for Authorities Governing Interconnection Requirements (AGIR) to immediately adopt IEEE Standard 2800-2022; and (4) FERC's RM22-12-000 NOPR on Reliability Standards to Address Inverter Based Resources.

PRR 151 is based upon a critical subset of IEEE Standard 2800-2022 requirements, as ammended for the NYCA.  Further revisions to encompass all pertinent IEEE 2800-2022 requirements will be included in subsequent PRR revisions.

The proposed Reliability Rule -- PRR 151 is expected to be effective for the next Class Year after Class Year 2023 is completed.  However, each IBR project developer is strongly encouraged to voluntarily follow the rule for current projects as other proceedings such as the FERC's RM22-12-000 NOPR are pending final decision.

The advantage to adoption of PRR 151 is that it establishes IBR interconnection criteria critical to maintaining the NYCA reliability as the NYCA transitions to renewable resources per CLCPA mandates.

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.

  • NYSRC Notice Regarding Inverter Based Resources (IBR) Actions
    Climate Leadership and Community Protection Act (“CLCPA”) Legislation recently enacted in New York State has mandated a very significant increase in Inverter Based Resources (IBR) on the New York State electric system. In light of this legislation, and after extensive review, the New York State Reliability Council (NYSRC) identified the need for, and is in the process of implementing, a number of actions necessary to preserve to New York State Bulk Power System.  The complete notice and summary of the actions may be found here.
