Geomagnetic Disturbance Reliability Standard; Reliability Standard for Transmission System Planned Performance for Geomagnetic Disturbance Events

The Federal Energy Regulatory Commission (Commission) approves Reliability Standard TPL-007-2 (Transmission System Planned Performance for Geomagnetic Disturbance Events). The North American Electric Reliability Corporation (NERC), the Commission-certified Electric Reliability Organization, submitted Reliability Standard TPL- 007-2 for Commission approval. The Commission also directs NERC to develop and submit modifications to Reliability Standard TPL-007-2: To require the development and implementation of corrective action plans to mitigate assessed supplemental GMD event vulnerabilities; and to authorize extensions of time to implement corrective action plans on a case-by-case basis. In addition, the Commission accepts the revised GMD research work plan submitted by NERC.
