Now National Grid Proposing Transmission Line To Import Quebec Hydropower Into New England
March 29,2017
National Grid has announced a proposal to develop a new transmission project that would bring up to 1,200 megawatts of energy from Canada to the New England power grid.
The proposed Granite State Power Link (GSPL) would 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.
National Grid said, "GSPL is a commercial project; its development will be funded by National Grid and its investors, not customers of its regulated companies."
National Grid claimed, "The project is also expected to lower energy costs across New England by $1.1 billion over its first 10 years of operation."
