I&M says it has deployed at least 140 electrical workers to help with the cleanup.
Before the storm made landfall Monday evening, New Jersey's largest power company reported at least 500 thousand outages. Experts say those could climb into the millions as Sandy makes its way through the Mid-Atlantic and into New England.
Ambulance services in Kosciusko and Noble Counties have also sent crews out east to help.
Meanwhile, the Indiana Red Cross is urging Hoosiers to donate blood. More than 100 blood drives were cancelled this week in 11 states because of Sandy.
