Maine’s §122 Energy Infrastructure Corridors

Studmill Road.jpg

First we had the Stud Mill Road. Vigue made claims that the East West Corridor would follow at least a portion of this route across Maine.

We found that this route also contained Power lines along with a Gas line at least a portion of the way and was designated the Consolidated Corridorby Maine’s Legislature. 

Bangor Hydro's

New Transmission Line to

Parallel Existing

Utility Corridors

September 17, 2004


BANGOR, Maine -- Bangor Hydro-Electric Company today announced the "Consolidated Corridors Route" as the preferred route for the Northeast Reliability Interconnect project, a proposed new 345 kV transmission line connecting eastern Maine with New Brunswick, Canada. One of five route options under consideration since Sept. 2003, the Consolidated Corridors Route was chosen based on a matrix of nearly 70 criteria developed with feedback from state and federal environmental review agencies, major landowners and interest groups.

The Consolidated Corridors Route generally parallels the existing MEPCO Transmission Line from Orrington, Maine to the Stud Mill Road. The route then follows the Stud Mill Road and the natural gas pipeline right-of-way to cross the international border at Baileyville, Maine. While neither the shortest nor the least costly route considered, the Consolidated Corridors Route will require the least amount of virgin right-of-way and will impact the fewest number of individual landowners.

The Consolidated Corridors Route is co-located with existing road and utility corridors for 96 percent of its length, minimizing environmental impacts and allowing construction and maintenance access via the Stud Mill Road. This type of co-location is consistent with the regulatory preference to co-locate utility projects wherever feasible. Bangor Hydro selected this route based on feedback from stakeholders and the Natural Resources Council of Maine's intervention and opposition to a previous route that was co-located for only 26 percent of its length.

"We are confident that locating the transmission line along the Consolidated Corridors Route best achieves the project purpose while balancing landowner, environmental and economic considerations," said Rob Bennett, Bangor Hydro's General Manager of Asset Management.

The Consolidated Corridors Route was selected on the basis of evaluation criteria measuring such factors as project purpose, impacts to wetlands, rare plants, wildlife, fisheries, recreational resources, archeological sites and project cost. Bangor Hydro received valuable input on environmental, engineering and cost criteria for the project throughout the year-long analysis and selection process.

"Feedback from stakeholders will continue to be important during the next phase of the project as we refine or 'micro-site' the route, minimizing the impact to sensitive resources," said Bennett. "As we move forward, the exact placement of the line will be carefully refined at each point from Orrington to Baileyville."

Once built, the NRI will improve the reliability and overall stability of the existing transmission system, increase the electric transmission import/export capabilities between Maine, New England and the Maritimes, and improve the efficiency of the existing system by reducing the electric energy lost during transmission. The NRI will also expand economic access to the US electric grid for residents in Washington and Aroostook counties. Furthermore, the benefits of the NRI will be felt across all of New England and the Canadian Maritimes.

"This transmission line is critical not only to Washington County, but to the entire State and region. The blackout on August 14, 2003 clearly demonstrates that we can no longer take for granted the reliability of the regional transmission system," stated Senator Ed Youngblood, member of the Maine Legislature's Utilities and Energy Committee. Although Maine shares over 600 miles of border with Canada, there is only one bulk transmission line linking the two regions and their electrical system operations. Providing a parallel path to the existing aging line, is a prudent measure to address both system reliability issues and economic opportunities.

Public outreach efforts will continue throughout the permitting phase of the project in order to share information and to receive further input that will factor into route adjustment decisions for specific localized concerns. Federal Department of Energy and state Department of Environmental Protection permitting processes will consider public comments as well. Public notice of those sessions will be issued well in advance. Parties interested in more information on the project are invited to contact the Company directly at 1-800-499-6600 extension 2568 or through the website at:

Maine’s transmission lines are essential energy infrastructure. They move bulk power across the system and help deliver electricity to thousands of businesses and households. As with any type of infrastructure, it is important to maintain and upgrade the system, prepare for future growth and ensure the availability of safe and reliable power at the lowest possible price.

  The region needs a new transmission line from the Keene Road substation in Chester, Maine to a new substation in Pittsfield, Maine. This project will relieve congestion, reduce line losses, boost reliability and accommodate new generation from renewable resources.

As a Corridor this would not only allow for a future Gas or Oil Pipeline, but in a nearer future a Nestlé water extraction line from a “proposed” Lincoln location to connect to a St. Albans extraction facility.

   It is a collaborative effort of Central Maine Power and Emera Maine and will be developed as a MEPCO project.

  The two utilities currently own some land in the towns where this line will be built, but they will need to purchase additional easements to finalize a route for this new transmission line.


    Most of the acquisition for this project will take place through easements. An easement is a permanent right granted to another party to use land for a specific purpose. The easements we seek would be for the construction, use, access to and maintenance of transmission lines. The landowner usually retains all other rights. In some circumstances, and if the owner has a preference to sell the land, a purchase “in fee simple” is possible. Unlike an easement, a fee-simple or outright purchase is an actual transfer of ownership and rights to the land.

  When we approach an owner, we respect how important that land is to an individual or family. Therefore we work with the owner to decide on a location on their land that works for them. We are also committed to paying fair market value.

    When an agreement is reached, we usually seek to first acquire an “option” for the easement or land. An option is an agreement through which the owner commits to sell at an agreed-upon price for a stated period of time (usually two years). If the buyer decides to complete the purchase - or “exercise” the option - the option payment is applied to the total purchase price. If the option is not exercised, the landowner keeps the option payment.

    MEPCO covers the cost of most surveying, title work, and legal documentation for both types of right-of-way acquisitions. 


Small Interconnect needed from SMR to the MEPCO corridor.

It is surmised that Wind Power proposed projects from Aroostook County are awaiting approval of a competitive bid from ISO-NE prior to construction.

An alternative route is to feed back through Canada and interconnect with the underwater Atlantic Link. This would save thousands of acres of Maine’s forests.

Some resistance has formed in Corinna with a Moratorium effort to allow time for the Planning Board to update the Community’s plans for its future.



CMP wants to build 145-mile transmission line through western Maine

PPH Link

 It would carry hydropower from Quebec to Massachusetts under a plan that's competing with others in New England for developing clean-energy projects.

The 145-mile line would follow a corridor owned by CMP from Beattie Township, on the Canadian border north of Route 27 and Coburn Gore, through Farmington and Jay to Lewiston, where it would connect to the regional electric grid.

LePage wants to develop a new gas pipeline from Quebec

The governor says a new gas line could lower prices in Maine, but it would cost hundreds of millions of dollars and some people at a conference in Falmouth say the idea is unrealistic.

PPH Link

Existing Line - or - New line

If Atlantic Bridge is stalled into 2019, Silkman said, Appalachian gas could be routed through Ontario and Quebec and into western Maine on the Portland National Gas Transmission System pipeline, which connects with the Maritimes line in Westbrook. That roundabout path has been used in recent years but increases the cost of gas, according to Silkman, an economist and national expert on gas markets.

Atlantic Bridge customers on the Maritimes line are distribution companies, power plants and a paper mill. They include Bangor Gas, Casco Bay Energy, Maine Natural Gas, Summit Natural Gas of Maine, Woodland Pulp and Unitil, which is an “anchor” participant in the project.                         PPH Link

Would this new Gas Line sought by LePage travel the same ROW as the proposed CMP transmission line?

Since the CMP transmission line is designated as a Corridor, this may be the ultimate intent.

Why is this new CMP ROW width nearing 1,400 feet wide in some locations? Why through Maine at all other than interconnect more Wind along the way.

With a proclaimed 26,000 miles of existing transmission lines, it is time to engineer an upgrade of the grid to accommodate future needs within those boundaries.
