FERC approves NERC CIP-014-4 to strengthen physical security and risk assessments for critical transmission facilities
The Federal Energy Regulatory Commission (FERC) approved NERC Reliability Standard CIP-014-4, which strengthens physical security requirements for critical transmission facilities by establishing clearer risk assessment methodologies and a unified 36-calendar-month review cycle for identifying and evaluating vulnerabilities. The standard becomes effective October 1, 2028, and applies to approximately 344 transmission owners who must identify nearby facilities within 1,500 feet, conduct both steady-state and dynamic simulations, and assess consequences of potential losses using technically justified thresholds. This revision consolidates previous tiered assessment schedules and aligns requirements with broader planning standards to reduce assessment gaps and ensure more consistent evaluation of critical infrastructure risks.
Why it matters: Transmission owners and operators must prepare for revised compliance obligations beginning October 1, 2028, including more frequent risk assessments and stricter documentation of physical security methodologies, affecting capital planning and operational processes across the bulk electric system.
