Central Maine Power Company selected three contractors to receive a total of $524 million to lead construction of the largest transmission project in state history.

The three transmission line companies – MYR Group, Inc.; Irby Construction Co.; and Hawkeye LLC – are based in Illinois, Mississippi and New York, respectively. They will share responsibility for building nearly 440 miles of high-voltage lines as part of a team of more than 150 consulting firms, contractors and suppliers, including nearly 120 Maine-based companies, according to a CMP press release.

“We’re building a stronger, smarter grid for Maine,” said CMP President Sara Burns, in the release. “Nearly 1,000 people have worked on this project to date, and we expect as many as 1,000 jobs will be added in this next phase of construction.”

CMP plans to host a job fair for individuals, contractors and suppliers on Jan. 18 at the Augusta Civic Center.
