What is the Proposed CMP Corridor?
Central Maine Power (CMP) is proposing to build a 145-mile transmission line through the heart of Maine to send hydropower from Quebec to electricity customers in Massachusetts.
NRCM opposes the corridor because it is a bad deal for Maine. The line would permanently damage undeveloped forest and wildlife habitat, stifle Maine’s own 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.
- NRCM has joined with Appalachian Mountain Club and Sierra Club Maine in filing a lawsuit challenging the federal government’s closeted and flawed review of the CMP project. Read an op-ed about why we filed the lawsuit. An injunction blocking construction in Segment 1 has been issued by the First Circuit Court of Appeals while they hear an appeal of a lower court’s decision to reject our motion for preliminary injunction.
- NRCM is also a party to two other lawsuits, one challenging the Department of Environmental Protection’s flawed permit and the other challenging an illegal lease given to CMP to cross public lands. In March 2021, a state judge found that Maine had improperly given CMP the lease.
- CMP and Hydro-Quebec have spent a record-breaking $20 million on desperate political campaigns to influence Maine voters, employing high paid consultants and lobbyists, as well as questionable tactics. Hydro-Quebec’s spending has drawn scrutiny from Maine lawmakers because they are exploiting a loophole in state ethics laws that allows them to spend unlimited funds to influence Maine’s elected officials.
Top 4 Reasons NRCM Opposes 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 proposal would cut 53 miles of new line through undeveloped parts of Maine’s North Woods. The damage would 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 are firmly opposed to CMP proposal, according to a statewide poll. The opposition from Mainers is widespread and growing, especially in Western Maine where the transmission line would be located.
- In a stunning rebuke to CMP’s proposal, 25 towns have voted to oppose or rescind their support for the project.
- Two major unions and the Sportsman’s Alliance of Maine are also opposed to the project.
- The Maine State Federation of Firefighters has 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.

Why the CMP Transmission Line is Bad for Our Climate
Read blog by NRCM Staff Attorney Sue Ely, explaining why the CMP corridor is a bad deal for Maine and for the climate.
CMP’s proposal is not about climate. It’s about making CMP more money. It’s a shell game to sell existing hydropower to Massachusetts because they’ve agreed to pay more for it.
CMP’s line would 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 or listen to 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.
