The utility company has requested a 7 percent increase in revenues to support its electricity distribution operations.
The proposal submitted in January would increase electric bills by a total of $96 million to address increases in operating and maintenance costs, along with modernizing the electric grid.
The average residential customer would see monthly bills increase by $8.45 per month.
Local hearings are scheduled for April 3 in Barnstable at the County Complex Harborview Conference at 7 p.m., April 6 at the Plymouth South High School at 7 p.m. and April 24 in Tisbury at Katherine Cornell Theatre at 6 p.m.
The DPU will make a decision on the request by November 30.
If approved, new rates would take effect January 1.
