Blistering heat wave stressing nation's power grid


NEW YORK (AP) -- A lengthy, blistering heat wave that is blanketing the eastern half of the United States is putting significant stress on the nation's power grid as homeowners and businesses crank up their air conditioners.

Utilities say they're ready for high power demand and widespread electricity shortages or outages are unlikely. Lines and equipment are not fully taxed and there is more generating and transmission capacity available than usual because of the weak economy. Also, not many major storms are in the forecast, meaning fewer downed power lines.
