What is CMP's Proposed Transmission 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 CMP 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.
Army Corps of Engineers to Hold Public Hearing on CMP Corridor Project on Thursday, December 5, 2019, in Lewiston
Mark your calendar and plan to attend this important opportunity to speak out in opposition to this proposal. Learn more about the hearing.
You can email the Army Corps of Engineers directly at MainePublicComment@usace.army.mil to share your concerns about CMP's transmission line.
What you need to know about CMP's proposed transmission line:
- Widespread opposition to the project is growing every day. More than 20 Maine towns along the corridor have voted to oppose or rescind their support. A citizen’s initiative campaign is currently happening to place a question on the November 2020 ballot to stop the corridor from being built.
- There are several state and federal permits for the CMP corridor that still need to be issued, including by the Land Use Planning Commission, Maine Department of Environmental Protection and US Army Corps of Engineers.
- The Maine Public Utilities Commission (PUC) and Massachusetts Department of Public Utilities have approved the project, but those decisions have been appealed because of substantive failings in their decision making.
- CMP’s rushed planning and preparation for their corridor proposal has already been highlighted by the US Environmental Protection Agency as inadequate and harmful for the environment.
- There is no evidence that the CMP corridor would benefit the climate by reducing global greenhouse gas emissions.
Top 4 Reasons NRCM Opposes CMP's Proposed 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.
Listen to NRCM’s staff attorney Sue Ely discuss why NRCM opposes the corridor.
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, 23 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 September, 2019, Maine people opposed to the project announced they have a launched a citizen’s initiative campaign for the November 2020 ballot that would overturn a decision by the Maine Public Utilities Commission (PUC) to approve the project.

Why the CMP Corridor is Bad for Maine’s Forests and Wildlife
CMP’s proposal would cut 53 miles of new transmission 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.
Why the CMP Transmission Line is Bad for Our 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.
