Canada has hydropower, and New England states are losing some of their coal-fired power plants. Transmission Developers has unveiled a plan for a 150-mile-long transmission line from Canada to Vermont that would bring 1,000 megawatts of hydropower to New Englanders. The line would be completely underground -- and under Lake Champlain. The company plans to line up financing by the end of 2017 and could break ground on the $1.2 billion project in 2018. Northeast Utilities also has plans for a 187-mile-long line from Quebec to New Hampshire, but because that line would be above ground, there is strong opposition.
