PJM Interconnection, the grid operator for the US Mid-Atlantic states, issued a maximum emergency generation alert early Friday, warning of a potential power supply shortage due to hot weather and heavy air conditioner use.

Temperatures in the Pennsylvania-New Jersey-Maryland (PJM) region were forecast to be in the mid-90� F. range in Philadelphia and Washington, DC.

A maximum emergency generation alert is the first step taken by the grid operator to prepare the electricity market for possible shortages. At 10:30 EDT, the PJM issued a manual dump load warning for the Erie, Pa., area that was canceled Friday afternoon. That warning was issued to control an overload on the Erie West 345 kv transformer.

PJM forecast of a peak load of 44,000 Mw for Friday exceeded earlier projections by 2,000 Mw.
