Green Line is a high-voltage direct current (HVDC) transmission system designed to transmit up to 1,075 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.
The New England States Committee on Electricity (NESCOE) sent a letter to ISO-NE on January 21st announcing an agreement of the six New England States to issue “one or more requests for proposals…to advance the development of transmission infrastructure that would enable delivery of at least 1200 MW and as much as 3600 MW of clean energy into the New England electric system from no and/or low carbon emission resources.”… (Read the full letter.)
Green Line will strengthen the transmission grid in New England and help provide greater access to competitively priced non-carbon emitting resources in Maine and eastern Canada. Read more…
