The regional grid operator, PJM Interconnection, said Monday that it has enough electrical power on hand to meet anticipated peak demand this summer on the most sweltering days.

PJM, in its annual reliability assessment, said Monday that peak demand is expected to reach 153,000 megawatts this summer, up slightly from last summer but short of the record 166,000 MW in 2006. PJM has nearly 186,000 MW of installed generating capacity available, plus it can draw upon 9,120 MW of  resources from customers who can curtail demand during peak times. Forecasters anticipate above-average temperatures this summer.

Audubon, Montgomery County-based PJM operates the power grid in 13 states and the District of Columbia, an area of about 65 million people. Its territory includes all of New Jersey, Pennsylvania, and Delaware.
