Heat Wave Roasts U.S. -- Can the Grid Handle It?

"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.

The heat wave began a week ago in the Plains states and is expected to spread east through the weekend. It is lasting longer than most heat waves and is spread over an unusually wide area, according to Travis Hartman, the Energy Weather Manager at MDA Earthstat, which proves forecasts for utilities and other weather-dependent businesses."
