PJM has issued a Maximum Generation Alert and Load Management Alert for June 23 due to hot weather across its 13-state region, including the District of Columbia.
The alert, which does not require customer action, is targeted at transmission/generation owners who will assess whether maintenance or testing on equipment can be postponed. By doing so, units remain online and continue to generate energy needed by customers.
PJM also issues a Load Management Alert to notify neighboring regions about potential curtailment of electricity exports outside the PJM footprint. The alert coincides with a forecasted load across the RTO of approximately 160,000 MW on June 23, 158,000 MW on June 24, and 155,000 MW on June 25.
A National Weather Service prediction of hotter-than-normal conditions this summer has prompted PJM to take proactive measures. The alert is a routine step in preparation for expected high temperatures, which drive up electricity demand.
PJM’s record summer peak was set in 2006 at 165,563 MW, and the organization has approximately 179,200 MW of generation capacity and 7,900 MW of contracted demand response this summer. A dedicated team of operators uses advanced technology to balance supply and demand, ensuring a stable electricity supply.
PJM’s emergency procedures include issuing alerts like the Maximum Generation Alert, which is triggered by conditions where all available resources are committed to meet electricity load and firm transactions, and reserve commitments are at risk.
