Client Alert

On Sept. 22, the Federal Energy Regulatory Commission (FERC) adopted Order 830, which revises reliability standard TPL-007-1 related to geomagnetic disturbances (GMD). The new standard requires transmission and generator owners, planning coordinators and transmission planners to assess the vulnerability of their bulk power systems to a benchmark one-in-100 year GMD event and create corrective action plans for those vulnerabilities. FERC also adopted certain modifications to the North American Electric Reliability Corporation-proposed draft standard to:

  • Modify the benchmark GMD event definition clarifying the definition is not based solely on spatially-averaged data;
  • Require the collection of additional current monitoring and magnetometer data and make it public; and
  • Include firm deadlines of one year to develop corrective action plans and two years (non-hardware issues) or four years (hardware issues) to complete mitigation plans.

The rules have not yet been posted on the Federal Register, but will be effective 60 days thereafter.
