HALLOWELL, Maine — Regulators are giving Mainers another chance to weigh in on a proposed hydropower project.

Maine’s Public Utilities Commission will hold a third public hearing Wednesday in Hallowell. The commission’s examiners’ report on the project is set for release Dec. 7.

The New England Clean Energy Connect aims to bring vast amounts of hydropower from Quebec to meet the needs of Massachusetts energy users. Supporters say the project will save Massachusetts and Maine ratepayers hundreds of millions of dollars a year.

Critics question its economic benefit and environmental impact.

The power corridor would run from Beattie Township, on the Canadian border north of Coburn Gore, through Farmington and Jay to connect with the power grid in Lewiston. It would cross the Kennebec Gorge, a scenic, 10-mile stretch popular with whitewater rafters.
