The Maine Power Reliability Program will see 450 miles of new or rebuilt transmission lines, along with five supporting 345-Volt substations, over the next five years.
The new power line will pass through 75 cities and towns, connecting with the Canadian grid in the north by the town of Orrington, and with the New England grid near the New Hampshire border to the south.
Iberdrola, the parent company of local utility Central Maine Power (CMP), said the project should support around 2,000 jobs each year of the construction phase.
It is to be the largest electrical infrastructure project in Maine’s history, and the first major grid upgrade in 40 years.
“The transmission project will be one of the largest construction projects in Maine’s history,” said Sara Burns, President of CMP. “Our state will have a smarter, stronger grid when it’s complete. While the project is about building critical infrastructure to serve Maine for generations, in the short term it will mean jobs when Maine needs them.”
Maine Governor John E Baldacci, who joined Iberdrola and CMP officials at a ground-breaking ceremony for the project at a substation in South Gorham, described the project as “critical” to the state’s infrastructure.
Gov Baldacci said: “Maine is rapidly becoming a recognized leader in renewable energy development, including wind power.
“We’ve moved aggressively in the State to reduce our dependence on fossil fuel, to develop domestic energy resources, and to encourage conservation and energy efficiency through investments in new technology. We need a reliable and effective infrastructure to harness and move this power.”
Meanwhile, Iberdrola also began installation of more than 600,000 new smart grid electricity meters in Maine yesterday, part of a $166 million program expected to be completed in 2012.
The project received $96 million in federal Recovery Act funds to support the upgrade in equipment, which will wirelessly transmit information to CMP and its customers regarding energy usage.
Offering real-time information on electrical usage, the meters are expected to help consumers use electricity more efficiently and help the utility reduce costs, improve planning and identify problems with its network more quickly.
Iberdrola USA CEO Bob Kump said: “Both the transmission project and the advanced meters will yield significant benefits in terms of reliability.
“Just as importantly, because the transmission project is a foundation for the development of renewable energy and the smart grid program will help customers reduce energy consumption, these projects are about protecting the environment for future generations,” Mr Kump said.
