A Toronto company financed by the US investment firm Blackstone is hoping to build a 2,000 megawatt power line between Montreal's south shore and New York City at a cost of $3.8 billion. The 570 kilometer line proposed by Transmission Developers Inc. (TDI) would largely be buried under Lake Champlain and the Hudson River in order to minimize its impact on the environment and local communities. The line, being called the Champlain-Hudson Power Express (CHPE) transmission power line, will be a high-voltage direct current (HVdc) cable.
