KENNEBUNK (AP) — Central Maine Power Co. has received approval from Kennebunk to upgrade the power grid, the last major hurdle in municipal permitting for the massive project.

The 5.5 miles of 345,000- and 115,000-volt electrical lines in Kennebunk will be part of the $1.4 billion Maine Power Reliability Program, which involves 450 miles of transmission lines.

The Journal Tribune says Kennebunk granted approval last week. The only other town that has not granted approval is Bowdoin, and Carroll said CMP is delaying its permit request there because it’s good only for one year and the work is not scheduled to begin until later.
