NERC and SERC Reliability Corporation Submit Proposed Regional Reliability Standard PRC-006-SERC-02

On September 8, 2017, in Docket No. RD17-9-000, NERC and SERC Reliability Corporation submitted a joint petition for approval of proposed regional Reliability Standard PRC-006-SERC-02 (Automatic Underfrequency Load Shedding Requirements). Proposed regional Reliability Standard PRC-006-SERC-02 establishes consistent and coordinated requirements for the design, implementation, and analysis of automatic UFLS programs among all SERC applicable entities. In particular, the proposed standard adds requirements to address: (1) identifying a Planning Coordinator’s subregion as an island; (2) developing a UFLS plan to meet specified criteria; (3) conducting simulations for load and generation imbalance UFLS schemes; (4) implementing the UFLS scheme for entities with loads 100 MW or greater and for entities with loads less than 100 MW; (5) implementing changes to the scheme within a specified timeframe; and (6) providing certain information to SERC. The NERC Board of Trustees adopted the proposed standard on August 10, 2017.
