WALTHAM, Mass. - March 28, 2017 - National Grid today announced a proposal to develop an innovative, new transmission project that would bring up to 1,200 megawatts of clean energy from Canada to the New England power grid. To drive down costs, increase efficiency and minimize environmental impacts, the proposed Granite State Power Link (GSPL) will be constructed almost entirely along existing transmission corridors and will maximize use of existing infrastructure.
As proposed, the GSPL comprises two segments: the first is a new high-voltage, direct current (HVDC) overhead line located in Vermont alongside an existing HVDC line in an expanded right-of-way corridor from the international border at Norton, VT, to a proposed converter station on National Grid-owned property in Monroe, New Hampshire. The second segment is an upgrade of an existing National Grid overhead line in NH to accommodate the additional power flow from the new HVDC line. That line runs from Monroe to southern NH, where a proposed switching station would be built.
