New Hampshire utility proposes transmission line from Canada to carry renewable power to New England

The newest proposal for a major electrical transmission line from Canada that would be able to carry power to New England from Canada, would also be able to send to Quebec renewable energy produced by future power generators off the New England coast or other sources. 

The proposed 211-mile, $2 billion Twin State Clean Energy Link would enter the United States in Canaan, Vermont. 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. 

“You can think about the Twin States line almost like battery storage -- the line would not need to be ‘always on’ and delivering energy from Quebec to New England,” said a statement from the electric utility National Grid, one of the developers of the proposed New Hampshire project. “Instead, it would be used when there is a need to bring additional clean energy to the region to balance variable resources, such as offshore wind.”  

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.
