National Grid Proposes to Develop 1,200 MW HVDC Transmission Project

LCG, March 30, 2017--National Grid announced Tuesday a proposal to develop a new transmission project to deliver up to 1,200 MW of energy from Canada to the New England power grid. The proposed Granite State Power Link (GSPL) will be constructed almost entirely along existing transmission corridors to reduce costs, maximize use of existing infrastructure and minimize environmental impacts. National Grid expects the project will lower energy costs in New England by $1.1 billion over its first ten years of operation.

The GSPL will be a commercial project funded by National Grid and its investors, not customers of its regulated companies. Investors include Massachusetts-based Citizens Energy.

As proposed by National Grid, the GSPL will be comprised of 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 (ROW) corridor from the Canadian border at Norton, Vermont, to a proposed converter station on National Grid-owned property in Monroe, New Hampshire.

The second segment will upgrade approximately 107 miles of existing National Grid-owned overhead lines from Monroe to southern New Hampshire to accommodate the additional power flows from the new HVDC line. The southernmost portion of the project also includes a proposed switching station and a few miles of related new transmission lines.
