Green Line is a high-voltage direct current (HVDC) transmission system designed to transmit 800 to 1,000 megawatts (MW) of electricity from northern Maine to southern New England. Green Line will support the development of renewable energy projects in northern New England that are needed to enable the region to meet its renewable energy and greenhouse gas reduction goals. Its direct current connection between northern and southern New England bypasses constraints on the existing alternating current (AC) grid between Maine, New Hampshire, and Massachusetts.
