PJM has again extended a Hot Weather Alert for its Mid-Atlantic region amid ongoing 90-degree weather.

A Hot Weather Alert is already in effect for today for the Mid-Atlantic and Southern regions.

A Hot Weather Alert helps to prepare transmission and generation personnel and facilities for extreme heat and/or humidity that may cause capacity problems on the grid. Temperatures are expected to go above 90 degrees, which drives up the demand for electricity.

The Mid-Atlantic region is made up of the Atlantic City Electric, Baltimore Gas and Electric, Delmarva Power & Light, Jersey Central Power & Light, Met-Ed, Penelec, PECO Energy, Pepco, PPL Electric Utilities, PSE&G, and Orange & Rockland (Rockland Electric Company) transmission zones.

The PJM Southern region consists of Dominion Virginia Power’s service territory.

PJM has performed reliability studies at even higher loads than its expected summer peak of 149,000 MW – in excess of 157,000 MW.

PJM has approximately 185,000 MW of installed generating capacity available to meet customer needs, with sufficient resources available in reserve to cover generation that is unexpectedly unavailable or for other unanticipated changes in demand.

PJM experienced its highest load of 2022 so far on July 20, and that day’s preliminary estimates showed demand hitting approximately 148,400 MW. The peak for Aug. 3 is projected to be approximately 145,000 MW. Last year’s peak demand was also around 149,000 MW.

A dedicated team of operators uses sophisticated technology to balance supply and demand and direct the power grid 24/7 from PJM’s control rooms. They prepare multiple potential scenarios that could be impacted by weather, emergency conditions or equipment failure. They adjust resource output with changes in demand and ensure that no transmission lines or facilities are overloaded. The team also watches for unusual conditions and reacts to them to protect the electricity supply. Read more about how PJM forecasts electricity demand on the PJM Learning Center.
