PORTLAND, Maine – Construction on part of a $1 billion electricity transmission corridor through sparsely populated woods in western Maine is on hold because of legal action, but that doesn't mean all building has been halted.

Workers installed the first of 829 steel poles Tuesday on a widened portion of the existing corridor that is part of the project near The Forks, as the groundwork is laid for the 145-mile (230-kilometer) New England Clean Energy Connect.

The work is getting started even though the 1st U.S. Circuit Court of Appeals delayed construction of a new 53-mile (85-kilometer) section.

Three conservation groups are seeking an injunction to delay the project while they sue to force the U.S. Army Corps of Engineers to conduct a more rigorous environmental review.

In western Maine, workers already have staged heavy equipment and timber “mats” that will be used to prevent the equipment from damaging the ground. About 275 Maine workers already have been hired, and more would be hired if not for the litigation, officials said.

“This project has always promised to provide an economic boost to Maine’s economy, and we are already seeing those benefits take shape," Thorn Dickinson, CEO of the New England Clean Energy Connect, said Tuesday.

The electricity transmission line would provide a conduit for up to 1,200 megawatts of Canadian hydropower, reducing greenhouse emissions and stabilizing energy costs in New England, supporters say.

The project, which would be fully funded by Massachusetts ratepayers to meet the state’s clean energy goals, calls for construction of a high-voltage power line from Mount Beattie Township on the Canadian border to the regional power grid in Lewiston, Maine.
