Maine Utilities Partner to Improve Grid

Emera Maine and Central Maine Power (CMP) have agreed to jointly develop electric transmission projects in Maine. The goal of all projects is to improve links between southern New England and northern Maine, where more than 2,100 megawatts of wind power development have been proposed. The agreement between the utilities comes in response to a call by the six New England governors for investments in the region’s energy infrastructure to diversify the energy portfolio and gain access to new renewable energy resources.

As the state’s two largest utilities, the companies serve more than 95 percent of Maine’s homes and businesses. The utilities have significant expertise with transmission projects, including the MEPCO transmission line that extends from central Maine to New Brunswick, Canada.

Transmission Project in MaineCentral Maine Power is the state’s largest utility serving 605,000 homes and businesses in the southern third of the state. The company is nearing completion of the Maine Power Reliability Program, a $1.4 billion investment in new transmission lines and substations to reinforce its 345,000 volt bulk power grid.

“Our Maine Power Reliability Program is the largest construction project ever in Maine, and one of New England’s largest transmission projects,” said Sara Burns, president and CEO of Central Maine Power. “It’s a vast and complex undertaking, but four years into construction, the project is on time and on budget.”

Emera Maine serves approximately 154,000 homes and businesses in eastern and northern Maine. Significant transmission projects completed by Emera Maine include the 43-mile, 115,000 volt Downeast Reliability Project, and the 85-mile, 345,000 volt Northeast Reliability Interconnect in 2007.

“Electric transmission can be a significant challenge to new low/no emitting generation sources seeking to enter our New England market”, said Gerard Chasse, president and COO of Emera Maine. “That’s a challenge that our companies have been working together on for some time, particularly in Northern Maine. With this MOU we are renewing and expanding these efforts to identify and develop creative and cost effective transmission solutions to benefit the State and the region.”

The partners have outlined two initial phases of work. Phase One will analyze the feasibility of each project, including technical feasibility, public policy, regulatory considerations, and outreach to other potential parties to the project. Phase Two will include all development activities from design, engineering, siting, through construction bidding.
