The 1,000-megawatt Champlain Hudson Power Express transmission line has been in development since 2008.
The project is aimed at saving about 2 percent to 3 percent on energy bills in New York City. The developer has said ratepayers also will see price breaks from Long Island to Albany.

Construction is expected to take about four years.
