The new Federal Energy Regulation Commission rule on geomagnetic disturbance events was one of several updates presented to the Planning Committee at its Oct. 6 meeting.
The FERC finalized a new reliability standard on geomagnetic disturbance events at its September 22 public meeting, accepting the two-stage process under which the North American Electric Reliability Corporation established the standard.
NERC developed a standard that identifies a “benchmark GMD event” against which asset owners and grid planners would be required to assess their equipment, and develop and implement mitigation. The NERC standard requires owners and operators of the grid to implement operating procedures to mitigate geomagnetic disturbance events effects (similar to PJM’s existing operating procedures to mitigate GMD events).
The standard has a five-year implementation plan, with the first step due in six months. In 2014, PJM and the PJM asset owners performed a GMD study and much of that work is applicable. PJM will work with transmission owners to develop a GMD program through the Planning Committee.
PJM issued a series of warnings on geomagnetic disturbance events the summer of 2015.
Other Committee Business
- Modifications to Manual 14B: PJM Region Transmission Planning Process regarding the capacity import limit Starting with the 2020/21 delivery year, the capacity import limit will no longer be applied as part of RPM. As a result, PJM needs to remove references to RPM from the calculation procedure.
- Proposed draft changes for Manual 21: Rules and Procedures for Determination of Generating Capability, related to generator testing requirements. The changes sharpen the language on the verification test timeframe and acceptance.
- PJM finished a week of stakeholder education on the Definitions Clean-Up Project and will present pending updates on the new glossary and retirement of Manual 35 at the October Markets and Reliability Committee meeting.
- Update on operational and planning protocols for the termination of the ConEd Wheel, which is anticipated in 2017.
- Updates to Manual 14A: Generation and Transmission Interconnection Process (the work of the Earlier Queue Submittal Task Force)
- Results of the 2016 Installed Reserve Margin study
- Changes to the Relay Subcommittee charter
- Changes to Manual 14C: Generation and Transmission Interconnection Facility Construction (relating to technical standards for Order 1000 projects). Stakeholders will vote on tie-line process language in November.
