Spot wholesale electricity declined on grids in the eastern U.S. as milder weather reduced demand for air conditioning.
Power consumption in New York City headed for a 12-week low while demand dropped in New England and the Midwest. Prices on the 13-state network operated by PJM Interconnection LLC slid for a fourth straight day along with electricity use.
Temperatures will be mostly below normal from New England through the Midwest and mid-Atlantic states until Sept. 10, according to WSI Corp. in Andover, Massachusetts. The high in Manhattan today may be 73 degrees Fahrenheit (23 Celsius) and Washington may be 77, 6 below normal for both cities, said AccuWeather Inc. in State College, Pennsylvania.
“We’ve got some weather that’s coming in that’s alleviating some of the cooling load,” said Michael Harris, chief executive officer of Unified Energy Services LLC, the Houston-based retail energy consulting unit of brokerage Tullett Prebon Group Ltd.
