PJM Interconnection Issues Hot Weather Alert For Entire Footprint For June 2

The regional electric grid operator PJM Interconnection has issued a Hot Weather Alert for June 2 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.

UPDATE: As of Friday morning, demand for electricity on Friday is expected to be 126,493 MW at 5:00 p.m. with total scheduled capacity of 142,946 MW as of 5:00 a.m.  [PJM Twitter]

PJM is expecting to serve a forecasted summer peak demand for electricity of approximately 156,000 MW but 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.
