Mega international power transmission line wins federal approval

The U.S. Department of Energy gave its approval this week to a 1,000-megawatt international power line that will carry mainly Canadian hydroelectric energy to southern New England. Vermont will have dibs on 200 megawatts.

The Department of Energy awarded the project a presidential permit, which is required for all projects crossing the United States border, said the Dec. 12 Federal Register, in which the project’s approval was recorded.

The power line, to be built by Transmission Developers Inc.-New England (TDI-NE) under the New England Clean Power Link moniker, will carry electricity produced from hydroelectric dams in Canada and wind turbines in New York to southern New England utilities that are statutorily obligated to secure portions of their energy supply from sources deemed renewable.

The project is the first of more than half dozen proposed by “merchant” electricity purveyors hoping to tap into that growing market to secure a presidential permit. The project last month was awarded certification from Independent Service Operator-New England (ISO-NE, the region’s electrical grid overseers) stating that it would be compatible with the existing New England grid.

The cable will carry 1,000 megawatts of direct-current electricity 154 miles from the Canadian border to Ludlow, where a converter station would transform the electricity to alternating current. From the Coolidge Substation in Ludlow and Cavendish, the power will flow into the ISO-New England grid, VELCO spokesman Kerrick Johnson said.

Most of the cable’s length from the Canadian border will be buried beneath Lake Champlain.

The Vermont Public Service Board approved the project early this year, saying that it issued a certificate of public good to TDI because the project diversifies energy sources, reduces greenhouse gas emissions, creates new jobs, generates tax revenue and potentially supplies cheaper energy.

The $1.2 billion project will carry roughly the same amount of power Vermont consumes as a whole.

The project’s backers — financial firm Blackstone Group, which manages more than $200 billion in assets — reached an agreement last year with the Conservation Law Foundation that secures almost $300 million over 40 years for the state’s cleanup efforts in Lake Champlain. The environmental advocacy group negotiated more than $100 million in addition to what TDI originally promised, and in exchange CLF agreed not to oppose the project in the courts.

Those payments are on top of $136 million to be disbursed to the state’s electricity transmission utility, Vermont Electric Power Co. (VELCO), in annual payments over 40 years. That money will be used to keep electric rates lower than they’d be otherwise, Johnson said, and will reduce the cost of transmitting electricity to Vermont by about 10 percent.

The payments will go to VELCO because it’s the state’s electric transmission utility, of which all 17 of Vermont’s power utilities are members, Johnson said.

Although the TDI cable will reduce power costs somewhat for retail customers, electricity prices will continue to be set, in the short term at least, by the cost of natural gas, the combustion of which supplies more than half of New England’s electricity.

Although New England’s reliance on natural gas is slated only to increase over the next decade, states in the region have committed to aggressive renewable energy targets incorporating wind, hydroelectric and solar energy. The TDI cable is meant to aid New England utilities in meeting these targets, Johnson said.

Construction on the project has been scheduled to begin in 2018, and if it moves forward, the New England Clean Energy Link should carry power by 2019.

Though the cable is meant primarily to serve New England states south of Vermont, its existence will spur further, subsidiary transmission projects within the state, Johnson said.

    Any of this RE slated for Vermonters?? Or is that a no no because of our so very high RE standards?

    • Paul Drayman

      Kim, I believe almost all of our electricity used in Vermont comes from the New England grid, which is where the energy from the above project is being shipped. In addition nearly all of the RE power produced by hydro, solar, and wind here in Vermont goes to the grid. It is mixed with power, 85% of which is produced by fossil fuels, and sold back to Vermont.
      The more RE power that gets produced outside of the cities that use the most electric power, the less incentive those cities have to build their own RE projects. Kind of a strange

  • Paco DeFrancis

    Great news. BUILD IT NOW! We need the tax revenue.

  • Paul Drayman

    I feel that this project is mostly good news for the New England grid. Two statements by Kerrick Johnson of VELCO mentioned in this article, however, are further evidence of the lack of commitment by the states and cities that create most of the demand, to develop their own R/E projects.
    Here is what he says: “…states in the region have committed to aggressive renewable energy targets incorporating wind, hydroelectric and solar energy. The TDI cable is meant to aid New England utilities in meeting these targets”
    “Though the cable is meant primarily to serve New England states south of Vermont, its existence will spur further, subsidiary transmission projects within the state”
    So, New England states will will achieve their “aggressive renewable energy targets” primarily by purchasing it from other areas. Additionally, new R/E projects will be built in Vermont, on Mtn. tops and in rural areas to feed demand elsewhere.

      Just hoping that Vermont is still in New England. During the past six years we, Montpelier, have been under the impression that we are an independent country and being ruled as such when it comes to RE.

      • Paul Drayman

        Yes, Vermont is still New England. It is epitome of what people envision when they hear the name N.E.. We are the least populated state in N.E. by far and consume the least electricity, We have committed to produce almost all of the power we consume with R.E., yet the rest of N.E. has not. 85% of electricity in N.E. comes from Fossil Fuels. Vermont could cover all of its mountains and fields with R.E. projects. That would create profits for developers and REC’s and help the rest of N.E. achieve its minuscule “aggressive renewable energy targets” and do little to change the fossil fuel content of the energy we all consume. This will be at the expense of VT’s scenic beauty, not to mention other great environmental impact. We are being told that we in Vermont are going to be energy independent with renewables. Not so !! Not even close.
