New England built a “clean energy bridge” to Canada, and when winter struck hardest, it went dark and sparked a $90 million battle over who left the lights off
When temperatures plunged well below zero Fahrenheit across Québec for 12 days this past winter, New England’s newest clean energy lifeline was expected to perform at peak capacity. Instead, the grid went unexpectedly quiet.
The New England Clean Energy Connect (NECEC)—a cross-border transmission line celebrated as a cornerstone milestone for regional climate goals—went dark when needed most.
Rather than sending a surge of emissions-free Canadian hydropower south, Canada’s grid halted exports. Now, that mid-winter freeze has sparked an intense legal battle over who should cover the soaring costs of replacement power.
They also had to purchase separate renewable energy credits to satisfy strict state environmental mandates—added costs they argue fall squarely on Hydro-Québec.
A celebrated transmission line, a brutal winter, and a sudden silence
NECEC had been running for less than a month when its first real operational stress test arrived. The transmission corridor officially began operations on January 16.
Within days, a brutal cold snap gripped Québec. As electricity demand inside Canada surged to unprecedented levels, Québec’s grid operator prioritized domestic heating needs and abruptly halted power exports south.
For 12 critical days across January and February, promised hydropower slowed to a mere trickle. The region’s flagship clean energy bridge became, in effect, a closed gate.
Massachusetts utilities were left scrambling for expensive replacement power on the open market at peak winter demand with no advance warning.
What the utilities say: $40 million in damages and a foreseeable failure
Eversource Energy, National Grid, and Unitil refused to accept the severe financial disruption quietly. All three utilities filed lawsuits against Hydro-Québec seeking $40 million in direct compensation.
Their argument centers on steep market penalties. When hydropower stopped, utilities had to buy substitute electricity generated by fossil fuels at dramatically higher spot prices.
They also had to purchase separate renewable energy credits to satisfy strict state environmental mandates—added costs they argue fall squarely on Hydro-Québec.
The utilities contend extreme Canadian winter cold is entirely foreseeable. Being unprepared for routine seasonal freeze-ups, they argue, represents an operational failure rather than an unpredictable emergency.
Hydro-Québec fires back: the grid operator decided, not us
Hydro-Québec draws a sharp legal distinction: it was Québec’s independent grid operator, not the corporate supplier, that ordered export halts during peak emergency conditions.
Under that interpretation, the stoppage was a mandatory grid reliability protocol beyond corporate control rather than a voluntary commercial default.
Hydro-Québec argues liability applies only if the company voluntarily chose to stop exports. Because provincial grid controllers issued the directive, the company claims it owes no financial compensation.
Furthermore, the underlying contract permits missing supply volumes to be delivered during later operational periods without causing a permanent default.
A line with a troubled first year: outages, reverse flows, and unmet targets
This winter standoff follows a pattern of wider operational turbulence during NECEC’s inaugural year. The transmission corridor suffered unexpected outage periods in the spring and again in late August.
By late July, NECEC had delivered 4.43 terawatt-hours of electricity—slightly under half of its 9.55 terawatt-hour annual contractual requirement.
Cross-border power dynamics further complicate the clean energy accounting. Even as hydro flowed south, New England sent fossil-fuel electricity north along separate interconnections to stabilize the grid.
Exporting gas- and oil-fired power north while importing clean hydro south creates an intricate environmental paradox for energy planners in both regions.
What’s at stake — and what experts say comes next
Despite early turbulence, clean energy advocates emphasize NECEC’s underlying value. Program managers at the Acadia Center note that contract disputes will not alter the project’s physical contributions to ISO New England.
Instead, legal experts view the clash as a vital learning opportunity for future international supply agreements.
As northeastern states negotiate upcoming renewable energy deals with Eastern Canada, this courtroom battle will define critical contract protections for decades to come.
What began as an arctic cold snap has now escalated into a high-stakes legal showdown. With utilities claiming $40 million in damages and Hydro-Québec countersuing for $50 million in unpaid bills, the dispute has exploded into a massive $90 million battle over who pays when clean energy lifelines freeze.
