Extreme Heat to Test U.S. Midwest Power Grid This Week
Electric companies are blaming consumers' air conditioning habits
The power grid operator in the Central United States said on Tuesday that it started to take some steps to make sure utilities are ready to keep the lights on as consumers crank up their air conditioners during an extreme heat wave this week.
Midcontinent Independent System Operator (MISO) said in a release that it told utilities to delay any discretionary equipment maintenance and to prepare emergency resources.
MISO operates the grid for some 42 million people in 15 U.S. central states from Minnesota to Louisiana and the Canadian province of Manitoba.
