(Reuters) – PJM Interconnection, the biggest U.S. electric grid operator, issued a level one emergency alert for Thursday as people crank up air conditioners to stave off the heat wave.
The operator issued an Energy Emergency Alert Level 1 late on Wednesday for July 27, signaling that it had available resources to meet firm load and reserve commitments, and was concerned about sustaining its required Contingency Reserves.

Demand is forecast to reach 153,286 MW as of 5:00 EPT on Thursday, and has approximately 186,000 MW of generating capacity.
Earlier this week, a hot weather alert was also issued for July 28 from 07:00-23:00 EPT
