On October 26, 2023, the Federal Energy Regulatory Commission (“Commission”) issued a Final Rule to retire 56 requirements from six different North American Electric Reliability Corporation (NERC) Reliability Standards. The retirement will go into effect on February 1, 2024. These Standards, often referred to as the MOD A Reliability Standards, consist of the following NERC Reliability Standards:
- MOD-001-1a (Available Transmission System Capability)
- MOD-004-1 (Capacity Benefit Margin)
- MOD-008-1 (Transmission Reliability Margin Calculation Methodology)
- MOD-028-2 (Area Interchange Methodology)
- MOD-029-2a (Rated System Path Methodology)
- MOD-030-3 (Flowgate Methodology)
This retirement concludes the last of the efforts identified under Phase 1 of the NERC Reliability Standards Efficiency Review Initiative that was first petitioned on June 7, 2019. NERC had assembled several working teams to identify potential compliance monitoring and enforcement efficiencies that could be achieved following the retirement or modification of various requirements from the INT, FAC, PRC, and MOD Reliability Standards families. Francis Esselman from PCS was an active contributor to one of these working teams. Under that initiative, NERC was able to retire 74 of 77 Reliability Standard requirements. The Commission was convinced that many of these requirements contained commercially focused elements facilitating interchange and frequency balance activities. These activities compliment, yet are independent, of reliability activities such as monitoring System Operating Limits and Real-time flows.
In 2021, the Commission did issue Order No. 676-J, a Final Rule that amended its regulations to incorporate by reference, with certain enumerated exceptions, the latest of the North American Energy Standards Board (NAESB) Wholesale Electric Quadrant (WEQ) Business Practice Standards. These standards are approved by an executive committee and adopted by WEQ members as mandatory enforceable requirements. The WEQ-023 Standard on Modeling addresses the technical issues that affect Available Transfer Capability (“ATC”) and Available Flowgate Capability (“AFC”) calculations for wholesale electric transmission services.
Clients of the PCS Standards Compliance Intelligence Portal (SCIP) were aware of the February 1, 2024, retirement a day after the announcement. SCIP is a web-based application that identifies standards in development and upcoming standards enforcement. The application is customized to each client’s needs and NERC registrations.
