Consumers Energy reported Tuesday afternoon that about 157,000 customers are still without service.
DTE Energy reports 49,000 outages, while the Lansing Board of Water and Light has about 12,000 without power.
The storm struck Saturday, leaving ice on roadways, tree branches and power lines. At least 488,000 utility customers lost power, many due to ice and branches pulling down power lines.
The utilities have said it would take days before most power can be restored because of the difficulty of working around ice-broken lines.
Authorities in the Upper Peninsula on Tuesday blamed slippery roads, speed and alcohol for a head-on crash that killed both drivers Monday evening.
