The Michigan Public Service Commission has directed DTE Energy and Consumers Energy to file reports on their responses to power outages from a March 8 windstorm.
Chair Sally Talberg says the commission wants to understand more of the lessons learned by Michigan utilities and their efforts to restore electric service.
The storm knocked out power to more than 1.1 million homes and businesses. Some customers didn't get their electricity restored until days later.
The reports are due May 15.
Both utilities are to review how the storm affected distribution systems, preparations and response to the storm and whether any changes could be implemented to reduce the potential for future power outages of the same magnitude.
Consumers Energy says in a release Tuesday that it welcomes the commission's review.
