is poisedto meet demand this summer with a peak demand forecast of 152,131 MW, the regionaltransmission organization said.

The operatorof the largest electric grid in the U.S. announced May 3 that the wholesale market,which includes Washington, D.C., and stretches across 13 states in the Midwest andMid-Atlantic, has 183,912 MW of installed generating capacity available and morethan 8,700 MW of demand response or load willing to be interrupted in case of asystem emergency. PJM's available resources represent a reserve margin of 28.3%,far above the required 16.4% margin, the grid operator said.

Includedin this available capacity for the first time will be resources that must produceelectricity when called upon regardless of weather conditions or extreme systemconditions. These committed resources will face significant penalties if they failto perform. PJM solicited voluntary offers of these resources in a transitionalcapacity auction in August 2015.The capacity performance product for PJM's Reliability Pricing Model forward capacitymarket was proposed in August 2014.

"Summertests the system as people try to keep cool in hot and humid weather," PJMVice President of Operations Michael Bryson said in a news release. "With continued transmission enhancements,reinforced capacity commitments and slowing forecasted load growth, we're preparedto meet the region's needs."

The summerpeak demand for electricity in 2015 that occurred on July 28 was more than 143,500MW. According to the RTO, the highest use of power within the PJM market was nearly166,000 MW, which occurred in 2006.
