Unit-Specific Parameters, Spring Restoration Drill Among OC Updates 

PJM presented the latest information on the upcoming Grid Ex IV Security Drill, spring restoration drill and updates on the unit- specific parameter process at the Operating Committee meeting on March 7.

PJM reviewed the results of the 2017 spring restoration drill, which is an annual two-day spring drill. The grid-wide drill requires 100 percent participation from all transmission owners to comply with  the North American Electric Reliability Corporation (NERC).

There were more than 250 participants on each day of the drill; PJM awarded almost 2,700 NERC continuing education hour credits.

PJM also presented an update on the unit-specific parameter process. More than 100 units submitted unit-specific adjustments for delivery year 2017/18. PJM is in the process of reviewing requests in advance of the April 15 notification deadline.

Unit-specific adjustments submitted Number of units Megawatts
Capacity Performance cleared for DY 17/18 98 13,110 MW
Replacement resources 5 551 MW
Total 103 13,661 MW

This year’s GridEx IV is scheduled for Nov. 15 and 16. The NERC sponsors the North America-wide grid resilience exercise every two years.

Grid Ex drills are designed to strengthen the industry’s capability to respond to and recover from simulated severe security events affecting the bulk power system.  Participants include grid operators, law enforcement, government entities and suppliers. NERC expects more than 4,000 participants this year.

PJM and stakeholders discussed the joint NYISO/PJM stakeholder initiative related to the phase angle regulators at the Ramapo substation. PJM will host the first of several joint meetings with the NYISO on Friday, March 10.

PJM also encouraged members to appoint representatives from their telemetry teams to participate in the Data Management Subcommittee (DMS). The next subcommittee meeting is May 9 and is an in-person only meeting. Instructions for joining the DMS can be found on PJM’s website.
