Breaking news (11/02/2021): Maine voters reject New England Clean Energy Connect and the dirty hydropower that it would carry in referendum vote


Multinational corporation Avangrid has proposed a transmission corridor for Canadian hydropower running through Maine. This corridor is commonly known as the CMP corridor or New England Clean Energy Connect (NECEC). This 145-mile transmission line will run through Maine to send electricity generated from hydropower from Quebec to customers in Massachusetts at an estimated cost of $1 billion.

Like other similar projects, this corridor will cut through miles of wilderness and undeveloped forests, disturbing wildlife habitat and threatening local clean energy production in Maine. This project will not reduce global greenhouse gas emissions or create long-term jobs for Maine residents.

The CMP transmission line was proposed in response to misguided energy policy in Massachusetts – a bidding process set in motion by the 2016 Energy Diversity Act in which power producers submitted proposals to the state to bring “clean” energy to the state.

The CMP project is locked in political and legal battles and has ignited a firestorm of opposition and according to the Natural Resources Council of Maine, 65% of Maine residents oppose the corridor. Opposition continues to mount, with towns along the corridor route renouncing prior support.

False claims about carbon-free energy

In step with Massachusetts Governor Baker and Governor Mills of Maine, Hydro-Quebec is promoting misinformation that the CMP will deliver “carbon free” electricity to Massachusetts. Here’s what NECEC says on its website:

In the NECEC application to Massachusetts for the CMP contract, most of the information about greenhouse gas emissions is redacted. Here’s one example:

Legal challenges continue to mount for the Maine corridor. On May 7, another power producer, NextEra Energy Resources filed a legal appeal of the permit issued by the Maine Public Utilities Commission. NextEra claims in part that the PUC failed adequately consider alternatives to the 145-mile power corridor, and the PUC’s conclusion that the power line will provide benefits to Maine was not supported by substantial evidence. On May 6, 2019, the U.S. EPA and Sierra Club wrote comments to the U.S. Army Corps of Engineers that the Clean Water Act and environmental review process for CMP are flawed and needs to start over. Sierra Club says a full environmental impact statement (EIS) under the National Environmental Policy Act (NEPA) is required before the project can proceed.

October 28, 2020 – Environmental Groups File Lawsuit Challenging Army Corps for Indefensible CMP Corridor Analysis

  • Appalachian Mountain Club (AMC), the Natural Resources Council of Maine (NRCM), and Sierra Club Maine are challenging the Army Corps for failure to rigorously assess impacts of the controversial transmission corridor on Western Maine.
  • The Corps’ inadequate assessment was completed July 7 but not released to the public. The groups received the document only after filing a federal Freedom of Information Act (FOIA) request.
  • Documents received by FOIA request show the Corps and CMP closely coordinated on the analysis behind closed doors and away from public scrutiny
Hydro-impacted community members hold a press conference at the Maine State House to discuss the CMP Corridor and the catastrophic impacts that the source of this power has on their communities and the environment.
