On July 3, the PJM Interconnection issued a Hot Weather Alert for July 5 for its entire footprint in anticipation of 90-degree temperatures.

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 across the footprint, which drives up the demand for electricity.

On July 5, PJM is expecting to serve a forecasted load of approximately 140,000 MW across the RTO.

The forecasted summer peak demand for electricity is approximately 156,000 MW, but PJM has performed reliability studies at even higher loads – in excess of 163,000 MW.

PJM has approximately 186,000 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.

Last year’s peak demand was approximately 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.
