Overview
Updated 1 hour agoEight days after a new transmission line began carrying Quebec hydropower into Massachusetts, Hydro-Québec shut it off. A cold snap had hit eastern North America, and Quebec chose to keep its own lights on first.
Eversource, National Grid, and Unitil filed a breach-of-contract suit in Boston federal court on September 9, seeking to recover $40 million they spent on dirtier replacement power. The case turns on whether a Quebec winter cold snap counts as force majeure. If Hydro-Québec wins, New England's plan to lean on imported hydropower has a hole in it.
Why it matters
If Hydro-Québec can cut exports whenever Quebec gets cold, New England's clean-energy plan rests on a switch Quebec controls.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
2017 class action against Eversource and Avangrid
A class-action lawsuit accused Eversource and Avangrid of manipulating natural gas pipeline reservations to raise New England electricity prices by 20%. The suit alleged the companies used legacy pipeline contracts to restrict gas supply and inflate costs.
The case highlighted chronic power cost problems in New England and the utilities' central role in them.
It underscored the region's dependence on constrained gas pipelines and imported power, the same vulnerabilities at issue in the Hydro-Québec dispute.
The 2017 suit shows New England's power market has a history of reliability and cost disputes. The Hydro-Québec case is the latest chapter in the region's struggle to secure affordable, reliable electricity.
January 2019 cold snap
An extreme cold snap across eastern North America pushed Quebec's grid to its limits. Hydro-Québec reduced exports to the US to keep the province's own lights on, leaving New England utilities scrambling for replacement power.
New England utilities paid higher prices for spot-market power during the cold snap.
The episode highlighted the structural risk of relying on Quebec hydropower during peak winter demand, but no legal action followed.
The 2019 cold snap is the direct precedent for the behavior at issue in the 2026 lawsuit. It shows Hydro-Québec has a pattern of prioritizing domestic reliability over export contracts during extreme cold.
2021 Texas winter storm (Uri)
A severe cold snap knocked out much of Texas's power grid, killing hundreds and causing billions in damage. Utilities and regulators fought over force majeure clauses and who bore the cost of failure.
Texas utilities faced billions in default power costs and a wave of lawsuits over force majeure claims.
The storm exposed how cold-weather events strain power contracts and grid reliability, leading to regulatory reforms in Texas.
Uri shows how courts and regulators handle force majeure disputes during extreme cold. The Massachusetts case raises the same question: when is a cold snap an emergency, and when is it just winter?
