Regional Reliability Standard PRC-006-SERC-01-Automatic Underfrequency Load Shedding Requirements

Under section 215 of the Federal Power Act (FPA), the Federal Energy Regulatory Commission (Commission) proposes to approve regional Reliability Standard PRC-006-SERC-01 (Automatic Underfrequency Load Shedding Requirements) submitted to the Commission for approval by the North American Electric Reliability Corporation (NERC). Regional Reliability Standard, PRC-006-SERC-01, is designed to ensure that automatic underfrequency load shedding protection schemes designed by planning coordinators and implemented by applicable distribution providers and transmission owners in the SERC Reliability Corporation (SERC) Region are coordinated to effectively mitigate the consequences of an underfrequency event. The Commission also proposes to approve the related violation risk factors, with one modification, and violation severity levels, implementation plan, and effective date proposed by NERC.
