Northern Pass proposes new transmission plan

The developer of a proposed $1.4 billion electric transmission line connecting Quebec to New Hampshire has released a revised route for the project, following public opposition to earlier plans.  The new vision for the Northern Pass project would bury more of the line underground and reduce the project's overall capacity to haul power.  Will this version of the Northern Pass gain more traction?

First proposed in 2009, the Northern Pass would be a 192-mile high-voltage direct current (HVDC) transmission line.  It would bring up to 1,000 megawatts of power from Canadian power plants into New England, running from the Canadian border to a proposed converter terminal in Franklin, New Hampshire.  From there, a new alternating current (AC) transmission line would deliver the energy to New England’s electric grid at an existing substation in Deerfield, New Hampshire. 

Since it was first proposed, the Northern Pass route has drawn criticism; the project was delayed, and despite revisions to the route public opposition remained.  Throughout the process, many comments have focused on local siting impacts, like the effect of above-ground transmission lines and poles through Franconia Notch State Park, the White Mountain National Forest, and the Appalachian Trail.  Eversource proposed running 8 miles of cable underground to reduce these impacts, but argued that undergrounding more would make the project too expensive.

But the forces motivating the Northern Pass project and other proposed HVDC lines from Canada remain strong: demand in New England and New York for electricity, and in particular for hydropower and other renewable electricity imported from Canada.

On August 18, project lead Eversource Energy announced changes to the route and scope of the project.  While the previous vision included 8 miles of underground cable to avoid visual impacts, the so-called "Forward New Hampshire Plan" now includes 60 miles of underground cable. Eversource described its revised route as striking "a balance between New Hampshire and our region’s need for a reliable new energy source and avoiding potential impacts to the state’s scenic landscapes."  At the same time, the revised proposal reduces the line's capacity from 1,200 megawatts to 1,000 megawatts, ostensibly to hold total costs at the previously estimated $1.4 billion.  The plan now includes $200 million to establish the "Forward NH Fund", a pool of money designed to support clean energy innovations, economic development, community investment, and tourism.

The Northern Pass project now faces public hearings.  Eversource is expected to file an application for site review with the New Hampshire Site Evaluation Committee in mid-October.

Northern Pass transmission line faces public hearings

A proposed high-voltage transmission line across the U.S.-Canada border in northern New Hampshire faces a series of public hearings this month.  The Northern Pass transmission line would provide an additional tie between Hydro-Quebec's electric grid and the New England grid, and would expand U.S. imports of electricity from Canada.

The project is proposed by Northern Pass Transmission LLC, an entity jointly owned by NU Transmission Ventures, Inc., a wholly-owned subsidiary of Northeast Utilities, a publicly held public utility holding company, and NSTAR Transmission Ventures, Inc., a wholly-owned subsidiary of NSTAR, a publicly held public utility holding company.

The project includes a high-voltage direct current or HVDC transmission line capable of transmitting up to 1,200 megawatts of power from Canada to the U.S. or from the U.S. to Canada.  45 miles of line would connect the northern HVDC converter terminal in Québec to the U.S.-Canada border into New Hampshire.  The line would extend south from the international border approximately 140 miles to an HVDC converter terminal that would be constructed in the city of Franklin, NH. 

Federal law governs the import and export of electricity.  To construct, operate, maintain, or connect an electric transmission facility crossing the borders of the United States, Northern Pass must first obtain a Presidential permit issued by the U.S. Department of Energy.  Under the National Environmental Policy Act, this approval requires the Department of Energy to consider the environmental impacts of granting the permit.

Since its unveiling in 2011, the Northern Pass project has provoked controversy.  The public has voiced concerns over the environmental and economic impacts of large-scale Canadian hydropower, the risk of private property being seized by the developer through eminent domain, and a route through New Hampshire's White Mountain National Forest and nearby mountains and woodlands.  In response, Northern Pass retooled its route, triggering a need to revise the project's environmental impact statement.  As part of that process, the Department of Energy has scheduled four additional scoping meetings in New Hampshire:

• Concord, NH, Grappone Conference Center, 70 Constitution Avenue, Monday, September 23, 2013, 6-9 p.m.;
• Plymouth, NH, Plymouth State University, Silver Center for the Arts, Hanaway Theater, 17 High Street, Tuesday, September 24, 2013, 5-8 p.m.;
• Whitefield, NH, Mountain View Grand Resort; Spa, Presidential Room, 101 Mountain View Road, Wednesday, September 25, 2013, 5-8 p.m.; and
• West Stewartstown, NH, The Outback Pub at The Spa Restaurant, 869 Washington Street, Thursday, September 26, 2013, 5-8 p.m.

Thousands of stakeholders attended the first round of scoping meetings in 2011, overwhelmingly expressing concerns about the project and its route.  While Northern Pass has made some efforts to address and accommodate these concerns, many - like New Hampshire Governor Maggie Hassan - continue to express concerns about the project's potential impacts on the White Mountain National Forest, as well as on New Hampshire's economy, environment, natural resources, communities and people.  This month's events may draw similar attendance to those in 2011 - the New Hampshire Congressional delegation has asked the U.S. Department of Energy to move the West Stewartstown meeting to Colebrook to accomodate more seating.  Public testimony at this month's scoping sessions will shape the Department of Energy's environmental review process, and may affect whether and how the line is eventually developed.

Copper thief apparently zapped

Copper wires and other electricity-related assets can be attractive targets for thieves -- but stealing electrical infrastructure carries risks beyond the legal realm.

The Associated Press is reporting that police have found evidence of an attempt to steal $100 worth of copper wiring from an electrical substation in Haverhill, Massachusetts.  The evidence, which reportedly includes a melted hacksaw covered in soot, suggests that a thief broke into the substation and came in contact with live wires carrying 23,000 volts.  Yesterday's incident apparently caused a small explosion and temporarily disrupted the power supply to the local area.  The police have stated that the would-be thief is likely severely injured or dead.
 
Copper thieves are presumably hoping to cut the metal out of its installation and sell it for scrap.  While the value of bulk quantities of scrap copper has been at a relative historic high, the Wall Street Journal reported yesterday that copper pricing has fallen due to expected decreases in European economic activity, selling on the New York Mercantile Exchange's Comex division for $3.39 per pound.  It would be a desperate thief indeed who risks electrocution for any price, let alone copper's scrap value.

This incident follows on a report earlier this month of the arguably more sophisticated theft of solar panels, inverters and batteries from U.S. Forest Service facilities in the White Mountain National Forest of New Hampshire.
