Severe thunderstorms cause historic power outage across Michigan, U.S. – more than 900 000 homes without power


Two rounds of severe thunderstorms hit Michigan from Tuesday to Thursday, August 10 to 12, 2021. Strong winds and heavy rains brought by the storm decimated the power supply network, leaving more than 900 000 homes and businesses without power.

Winds up to 110 km/h (70 mph) were registered in the metro Detroit area and between 50 and 100 mm (2 – 4 inches) of accumulated rainfall from both rainfalls, said NWS meteorologist Sara Schultz.1

"These three days of storm activity rank among the top 10 storms in our company's 135-year history," said Guy Packard, Consumers Energy’s vice president for electric operations.

Some 371 000 Consumers Energy customers were without power at the height of the storm, of those 184 000 had their power restored by 21:45 LT on August 12.

An additional 550 000 DTE customers were left without power, bringing the total to more than 900 000.

As of 19:50 UTC on August 13, a total of 628 480 customers remain without power.

  1. Way too much rain in 2021…

    The never ending rains have wrecked 30% of the wheat crop in Michigan. If it’s as wet in the fall then that will affect the apple and potato harvests. Last, the mosquitos are biblical like as a pestilence.
