The developer of the Northern Pass Transmission Project, a proposed high-voltage transmission line from Canada into New Hampshire, filed a formal application to New Hampshire regulators this week.
First proposed in 2009, the Northern Pass project would include about 190 miles of new direct current transmission lines and an AC-DC converter station. Collectively, the project would be capable of importing over 1,000 megawatts of power from Canada into the New England electric grid. Its formal sponsors are two companies affiliated under the Eversource family: Northern Pass Transmission LLC and Public Service Company of New Hampshire d/b/a Eversource Energy.
Early versions of proposal drew criticism and controversy over issues including siting, visual impacts, the potential use of eminent domain, and impacts to domestic renewable energy production. After a series of public information meetings and other dialogue, Eversource released a revised route and plan in August 2015.
On October 19, Eversource announced that it had filed a formal application to the New Hampshire Site Evaluation Committee. The Northern Pass Transmission application to the SEC is available on the project's website. It describes a project cost estimate of $1.6 billion, and a capacity of 1,090 megawatts.
The SEC was established by the state legislature for the review, approval, monitoring
and enforcement of compliance in the planning, siting, construction and
operation of energy facilities. It includes members from the
Public Utilities Commission, cabinet level commissioners,
and two members of the public. The SEC has jurisdiction to review applications for siting and construction of large-scale energy facilities and to issue a Certificate of Site
and Facility enabling a project's development. The process before the SEC is likely to play out through 2016.
