Project Overview

The Northern Pass transmission project will create a new connection between Hydro-Québec's world-class hydroelectric resources and the New England "power pool" that supplies electricity to all customers in the region—including New Hampshire.

The heart of this project is the construction of a direct current (DC) transmission line that will bring up to 1,200 megawatts of hydroelectric power into the region, providing much-needed fuel diversity, lowering energy costs, and lessening our reliance on fossil fuels.

Along with the construction of the DC line, the project will include the construction of a converter terminal in Franklin, NH to convert the electricity from direct current to alternating current (AC), as well as the construction of a new AC transmission line from the converter terminal to an existing substation in Deerfield, NH.
