BOSTON (AP) — A project aimed at bringing hydropower from Canada to Massachusetts through Maine has cleared a key hurdle.

Hydro-Québec and Central Maine Power Company announced Friday that they have successfully concluded contract negotiations with Massachusetts electric distribution companies for the New England Clean Energy Connect 100 percent hydropower project.

The agreement will allow for the delivery of about 9.45 terawatt hours annually of renewable power for 20 years. One terawatt-hour of electricity is enough to power 85,000 homes.

The energy will be supplied by Hydro-Québec's hydropower generating fleet. The Massachusetts electric distribution companies will now file the agreements with the Massachusetts Department of Public Utilities as part of the regulatory process.

Massachusetts had earlier hoped to transmit the energy through transmission lines across New Hampshire, but regulators there rejected the plan.
