Reliability Rule #151
RR #151 2-11-2024
Reliability Rule – RR #151- Reliability Rule B.5: Establishing New York Control Area (NYCA) Interconnection Standards for Large IBR Generating Facilities
On Friday February 9, 2024, the NYSRC Executive Committee approved Potential Reliability Rule PRR 151 – Establish minimum interconnection standards for Large Inverter Based Resource (IBR) Generating Facilities based on IEEE Standard 2800 – 2022 and its associated procedures document as Reliability Rule B.5: Establishing New York Control Area (NYCA) Interconnection Standards for Large IBR Generating Facilities for inclusion in its Reliability Rule & Compliance Manual.
The need for Reliability Rule B.5 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. In addition, the need for the new rule is demonstrated by the New York Independent System Operator’s (NYISO) Interconnection Queue as of 6/30/23 having greater than 120,000 MW’s of Large Facility (>20MW) Inverter Based Resources.
Reliability Rule B.5 addresses interconnection study and compliance requirements for “as-designed” IBR plants based on IEEE 2800-2022.

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.
