Project Update

New England Clean Energy Connect (NECEC), US [free access]

August 1, 2017

Developers: Central Maine Power and Avangrid 


Project details and status: The proposed project will provide a new link through a ±320 kV high voltage direct current (HVDC) transmission line between Hydro-Québec and the New England grid. In Maine, the line will begin at the Canadian border in western Somerset County and run 145 miles (234 km) to a new alternating current (AC)/direct current (DC) converter station in Lewiston. The new line, in combination with additional smaller improvements at various facilities in Maine, will have the capacity to deliver up to 1,200 MW of power from Hydro-Québec to Massachusetts. The NECEC is slated to become operational by 2022.


In July 2017, the developers submitted their project proposal to the Massachusetts Department of Energy Resources (DOER) in response to the request for proposal invited by the latter. According to a schedule of the State DOER, projects will be chosen by January 25 2018, negotiations will be completed by March 27 2018, and contracts will be sent to utility regulators for review by April 25 2018.
