New England has paid some of the highest electricity prices in the country for decades, hostage to constrained natural gas pipelines that spike costs every winter. On January 16, 2026, a $1.6 billion transmission line began delivering 1,200 megawatts of Canadian hydropower to the region—enough to meet 20% of Massachusetts' electricity needs and save ratepayers an estimated $50 million annually.
The 145-mile line took ten years from conception to operation, surviving a New Hampshire rejection, a Maine voter referendum funded by fossil fuel competitors, a state supreme court battle, and a nine-person jury trial. Within days of commercial launch, an Arctic cold snap forced Quebec to halt exports to serve its own customers. The outage raised questions about the line's reliability.

Fictional AI pastiche — not real quote.
"Ten years to string wire across a mere 145 miles—and then they find themselves dependent upon the goodwill of their northern suppliers at the first freeze! In my time, we laid railways through deserts and across veldt with greater speed and less squabbling, because we understood that infrastructure is empire, and delay is defeat."

Scenarios
1
NECEC Operates Reliably, Expands Regional Clean Energy
Likely
Discussed by: Massachusetts energy officials, Conservation Law Foundation, clean energy advocates
The transmission line delivers consistent power over its 20-year contract, reducing wholesale electricity prices and suppressing winter price spikes. Success emboldens similar projects and demonstrates that major transmission infrastructure can survive political opposition. Massachusetts uses NECEC power toward its 2050 net-zero emissions target, potentially prompting additional Canadian hydropower contracts.
Discussed by: New England Power Generators Association, energy consultants, critics of the project
Repeated instances of Quebec curtailing exports during cold snaps—when New England needs power most—raise questions about NECEC's reliability as baseload capacity. Massachusetts utilities or regulators seek contract modifications or penalties. The experience influences future transmission projects to include stronger delivery guarantees or penalties for non-performance.
3
Quebec Drought Conditions Reduce Available Power
Possible
Discussed by: Energy analysts, Hydro-Québec observers, Robert McCullough (industry consultant)
Three years of below-average precipitation have reduced Quebec's reservoir levels. If drought conditions persist, Hydro-Québec may struggle to meet both domestic demand and U.S. export commitments, particularly during extreme weather. This could force difficult allocation decisions and undermine the project's promised benefits to Massachusetts ratepayers.
4
Model for Future U.S. Transmission Buildout
Possible
Discussed by: Grid Strategies, Americans for a Clean Energy Grid, Department of Energy
NECEC joins the Champlain Hudson Power Express (expected operational spring 2026) as proof that major interstate transmission can be built despite intense opposition. The projects' success—surviving referenda, lawsuits, and political opposition—informs federal permitting reform efforts and regional transmission planning under FERC Order 1920.
Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
1971-2002
James Bay Hydroelectric Controversy (1970s-1990s)
Hydro-Québec built massive hydroelectric dams in northern Quebec, flooding 11,000 square kilometers of Indigenous Cree and Inuit territory. The James Bay project became one of North America's largest hydropower complexes at 16,000+ megawatts. Environmental and Indigenous rights groups in the U.S. and Canada campaigned against the projects, influencing the New York Power Authority to cancel contracts in 1992.
Then
Quebec negotiated land claims settlements and modified later phases of development. Some U.S. utilities reduced or cancelled Hydro-Québec contracts.
Now
Created lasting questions about whether Canadian hydropower should be classified as "clean" energy given ecological and Indigenous impacts. The 2002 Peace of the Braves agreement between Quebec and the Cree established a new framework for resource development.
Why this matters now
NECEC opponents argued that Hydro-Québec power is not truly clean energy due to reservoir methane emissions and Indigenous land impacts. These arguments appeared in the 2021 Maine referendum campaign and continue to shape debate about counting hydropower toward state renewable energy mandates.

2001-2017
Cape Wind Offshore Project (2001-2017)
Cape Wind was proposed as America's first offshore wind farm, with 130 turbines in Nantucket Sound. Despite federal permits and utility contracts, the project faced 16 years of lawsuits, regulatory challenges, and opposition from wealthy coastal residents and the late Senator Ted Kennedy. After losing power purchase agreements in 2015, developer Energy Management abandoned the project.
Then
Massachusetts lost the chance to lead offshore wind development; the project became a cautionary tale about permitting delays and organized opposition.
Now
The failure prompted Massachusetts to create a more structured offshore wind procurement process and led to current projects like Vineyard Wind. Demonstrated that even with permits, projects can be killed through sustained litigation and contract cancellations.
Why this matters now
NECEC faced similar dynamics—well-funded opposition, ballot initiatives, and years of litigation—but ultimately prevailed where Cape Wind failed. The difference: Avangrid had begun significant construction before the referendum, giving it constitutional protection that Cape Wind lacked.

February 2018
Northern Pass Rejection (2018)
Eversource proposed a 192-mile, $1.6 billion transmission line called Northern Pass to carry 1,090 megawatts of Quebec hydropower through New Hampshire to Massachusetts. The New Hampshire Site Evaluation Committee unanimously rejected the project, citing harm to tourism, communities, and landscapes. Eversource spent $318 million before the New Hampshire Supreme Court upheld the rejection in 2019.
Then
Massachusetts utilities pivoted to NECEC as the primary route for Canadian hydropower imports, making Maine the battleground for the regional clean energy debate.
Now
Demonstrated that even well-funded transmission projects can fail when local opposition is sufficiently organized, setting expectations for the fight NECEC would face in Maine.
Why this matters now
NECEC became the viable alternative only after Northern Pass failed, and the Maine opposition drew lessons from New Hampshire's successful resistance—including the power of framing transmission as an out-of-state benefit at local cost.
