Hot Weather Alert Issued for Mid-Atlantic and Dominion Regions for July 14 and 15

PJM has issued Hot Weather Alerts for its Mid-Atlantic and Dominion Regions for July 14 and 15.

The alert is being called because temperatures are forecast to be above 90 degrees Fahrenheit. No problems are expected at this time.

A Hot Weather Alert prepares transmission or generation personnel and facilities for extreme hot and/or humid weather conditions that may cause capacity problems on the grid. Transmission/generation operators determine if any maintenance or testing on their facilities can be deferred to a later date or even canceled.

Hot Weather Alerts do not trigger PJM’s Capacity Performance Assessment Hours for capacity resources, which PJM uses to assess a generator’s performance during selected emergency actions.

The PJM Mid-Atlantic Region consists of the service territories of the following transmission owners: Atlantic City Electric, Baltimore Gas and Electric Company, Delmarva Power, Jersey Central Power & Light Co., Metropolitan Edison Co., PECO, Pennsylvania Electric Co., Pepco, PPL Electric Utilities, Public Service Electric and Gas Co., Rockland Electric Company and UGI Utilities.
