Michigan regulators say two large utilities had emergency procedures in place and responded effectively to restore power after a December ice storm.
The Lansing State Journal reports Public Service Commission staff made the conclusion about Consumers Energy and DTE Energy in a report released this month.
Michigan regulators in January ordered an investigation into lengthy power outages stemming from the pre-Christmas ice storm that knocked out service to about 660,000 customers statewide, the vast majority served by Consumers Energy and DTE.
The report notes that utilities should continue to work to minimize the impact of future storms.
The Lansing Board of Water & Light, a municipal utility not regulated by the PSC, faced widespread criticism of how it handled outages that affected about 40,000 of its customers.
