In April 2023, a Cumberland County jury ruled in CMP’s favor during a court case that very likely will decide the future of the company’s controversial transmission corridor. The decision was based on technical legal issues and not on the merits of whether or not this was a good project for Maine
We are disappointed with the outcome and remain sharply focused on achieving a just and equitable clean energy future that works for all Mainers.
Maine has already shown there’s a better path forward than the CMP corridor. A path focused on regional collaboration and centered in Maine’s pragmatic approach to solving problems.
Mainers are pursuing home-grown clean energy sources, like the King Pine wind project in Aroostook County that will deliver new and verifiable reductions in pollution rather than a shell game that shifts existing energy for maximum profit.
Maine voters got it right when they overwhelmingly passed a referendum rejecting the CMP corridor because it’s a bad deal for Maine and a bad deal for our climate.
NRCM is honored to stand with youth climate justice activists, tribes in Maine and Canada, people across western Maine who rely on a vibrant outdoor recreation economy, and many others in opposing the CMP corridor. Thank you to everyone who partnered with us on this hard-fought campaign.
What is the CMP Corridor?
Central Maine Power (CMP) is building a 145-mile transmission line through the heart of Maine to send hydropower from Quebec to electricity customers in Massachusetts.
The CMP corridor is a bad deal for Maine. It will permanently damage undeveloped forest and wildlife habitat, stifle the local renewable energy industry, and jeopardize the creation of clean energy jobs. The corridor won’t reduce global greenhouse gas emissions or create sustainable jobs for Maine people.
Top 4 Reasons NRCM Opposed the Corridor:
- Won’t reduce climate-changing pollution, and may actually increase it.
- Cuts 53 miles of new transmission lines through undeveloped forests in Maine’s North Woods, harming brook trout, deer, other wildlife, and the tourism economy.
- Jeopardizes the construction of new in-state renewable energy projects and creation of clean energy jobs.
- Generates billions of dollars of profit for CMP and Hydro-Quebec while offering very little to Maine people and businesses.

Why the CMP Transmission Line is Bad for Maine’s Forests and Wildlife
CMP’s transmission line will cut 53 miles of new line through undeveloped parts of Maine’s North Woods. The damage could fragment the largest contiguous temperate forest in North America and perhaps the world.
- This destruction would clear trees and plants through 263 wetlands, across 115 streams, and near remote Beattie Pond.
- It would harm Maine’s deer herd by blocking access to deer winter shelter and feeding areas.
- It would cut right through the heart of Maine’s brook trout habitat, including areas where public agencies and private citizens have spent millions to protect brook trout.
Majority of Mainers Oppose CMP's Corridor
The vast majority of Maine voters firmly opposed CMP's proposal, according to a statewide poll. The opposition from Mainers is widespread, especially in Western Maine where the transmission line will be located.
- In a stunning rebuke to CMP’s proposal, 25 towns voted to oppose or rescind their support for the project.
- Two major unions and the Sportsman’s Alliance of Maine also opposed the project.
- The Maine State Federation of Firefighters expressed concern about the risk of fires.
- In February 2021, Maine Secretary of State Shenna Bellows certified that more than enough valid signatures had been gathered to place a citizens referendum on the November 2021 ballot opposing the CMP corridor.
25 Maine towns rescinded their support or came out in opposition to the proposed transmission line:
- Alna (rescinded letter of support)
- Anson (town residents voted (98-12) to oppose the project)
- Caratunk (rescinded letter of support)
- Chesterville (town residents voted to oppose the project)
- Dennistown (wrote letter in opposition to project)

- Eustis (town residents voted to oppose the project by a vote of 103-4 )
- Farmington (town residents voted to rescind support and oppose the project)
- Greenville (town residents voted (290-58) to oppose the project)

Why the CMP Transmission Line is Bad for Our Climate
Read our blog post explaining why the CMP corridor is a bad deal for Maine and for the climate.
CMP’s proposal was not about climate. It was about making CMP more money—a shell game to sell existing hydropower to Massachusetts because they’ve agreed to pay more for it.
CMP’s line will do nothing to reduce climate-changing pollution because there is no assurance it will result in new renewable energy being created.
- Read the analysis conducted by environmental and renewable energy groups that concluded that the CMP corridor would not reduce carbon pollution and therefore would have no benefit for climate change.
- Read about the concerns raised by the Massachusetts Attorney General's Office that CMP's power line would not reduce greenhouse gases.
- Read NRCM’s testimony in support of LD 640, which would have required an independent climate impact study for the project
CMP’s transmission line could make it harder for local renewable energy projects to move forward, costing Maine new clean energy jobs and stifling Maine’s burgeoning clean energy industry. Maine needs investments in renewable energy projects with real environmental benefits, not a massive and harmful transmission corridor that lines CMP’s pockets.
