The proposed 211-mile, $2 billion Twin State Clean Energy Link would enter the United States in Canaan, Vt. It would be buried along state highways in Vermont and New Hampshire until it linked to an existing transmission corridor in Monroe that would carry the power to a new substation in Londonderry. From there the power could be distributed throughout New England. Unlike much of the power currently brought to the United States from Canada that is generated by hydro generation facilities in Quebec, it would also have the ability to deliver power generated by wind and solar facilities in Canada. For years the Northeastern United States has tried to find ways to take advantage of hydropower produced in Canada and Canadian officials have been eager to sell power in the U.S. If approved, the earliest the New Hampshire project could begin construction would be 2026.
