The Granite State Power Link (GSPL), a project co-developed by National Grid and Citizens Energy, will deliver up to 1,200 MW of clean, reliable, affordable renewable power from Canada to New England. Staying within or adjacent to existing transmission corridors, GSPL will build approximately 58 miles of new HVDC (direct current) transmission line from a new converter station in northern Vermont to a new converter station in Monroe, New Hampshire. From Monroe, approximately 109 miles of AC (alternating current) transmission line will run to a new switching station in Londonderry, New Hampshire.

New England’s energy constraints, driven by retiring fossil fuel and nuclear generating plants, require immediate, cost-effective transmission solutions that will transport clean energy to benefit us now and in the future. GSPL is a solution to address this challenge by diversifying New England’s energy portfolio, helping states meet greenhouse gas reduction goals, and lowering energy costs for consumers. GSPL is positioned to minimize local and environmental impact, while bringing maximum benefit to host communities and the region.
