Massachusetts utilities sue Hydro-Québec for $40 million over missed NECEC deliveries; Hydro-Québec sues them for $50 million

Canary Media reported on 10 September 2026 that Eversource Energy, National Grid and Unitil, the three Massachusetts utilities contracted to buy power over the New England Clean Energy Connect (NECEC) line, are suing Hydro-Québec for $40 million in compensation after it largely stopped exports on the line for 12 days in January and February 2026 during extreme cold in Quebec. Hydro-Québec argues that Quebec's grid operator, not the company, decided to stop sending power south because of unprecedented demand, and that the contract lets it make up the volumes later; it is suing the utilities for $50 million it says they owe for power delivered in those months. According to Canary Media, the utilities contracted for 9.55 terawatt-hours a year, and 4.43 TWh had been delivered by the end of July, slightly less than half the annual obligation; the line began operating on 16 January 2026.

Claims that rest on this event

ComplicatesOutcome
New electricity export lines run south, not overseas. Two lines, to New England and New York, entered service in 2026 under contracts signed before the tariffs (about 20 TWh a year). But they mostly make up for sales Hydro-Québec is losing elsewhere: comparing a normal water year with a normal water year, Canada's energy regulator puts electricity exports at about 59 TWh in 2024 and about 57 TWh in 2034, so in the journal's model power adds about nothing to what reaches the US, like for like. The model doesn't forecast rain and snow. One caveat: 2024 was actually a drought year (Canada exported only about 36 TWh), so if 2034 is a normal year, the check in 2034 will make electricity look about US$2 billion a year better, for reasons that have nothing to do with building. The Churchill Falls deal adds no new line to the US; its power goes mainly to Quebec.
Delivery shortfalls and lawsuits on NECEC.

How it bears on the outcome

Explanation	Fit	Why
O0 No meaningful speed-up	Neutral weak	A contract dispute over a line agreed before the trade conflict does not bear on whether the build-out has sped up.
O1 Faster, but the extra output goes mostly elsewhere	Neutral weak	Quebec cut exports to serve its own demand in a cold snap; this is about domestic priority, not other foreign buyers, and fits O1 and O2 equally.
O2 Faster, and more volume reaches the US (this level or higher)	Neutral weak	The line adds US-bound volume, but it was contracted before the trade conflict, so it does not show a pressure-driven increase.
O3 Locked-in preferential terms for the US	Against weak	Hydro-Québec cutting US deliveries for domestic need and then suing the US buyers would be somewhat surprising under locked-in supply guarantees for the US.
