Export Of Hydroelectricity From Quebec To New England Plummets As Rates Fall
On March 6, at the start of the still-simmering trade war between the U.S. and Canada, hydropower generator Hydro‑Québec quietly stopped exporting electricity to New England. At a time of year when Canadian hydropower typically supplies up to a tenth of New England’s power, the region has instead gone almost a month with virtually no cross-border flow of electrons.
Hydro‑Québec leaders say low prices in the New England market — not politics — are behind the decision to suspend sales. The disruption hasn’t affected power costs or reliability in the region yet, but some experts say it could if the cutoff extends into the summer cooling season. The situation also highlights a potential risk to state clean energy plans that count on Canadian hydropower to help offset fossil fuels. “This shows the potential for the region to be vulnerable to manipulations of the supply,” said Phelps Turner, director of clean grid for the Conservation Law Foundation.

In an email from a company spokesperson, Hydro‑Québec attributed its lack of exports to market conditions, saying milder spring weather has lowered demand and thus prices. Others have theorized the move is also a show of power aimed at the Trump administration. Hydro‑Québec has been sending signals for a while that it might be moving away from delivering power to New England at its historic levels. Last year, 5,560 gigawatt-hours of power traveled into the region over the Phase II line, less than half the amount exported in 2022. And in the last two forward capacity auctions run by grid operator ISO New England, Hydro‑Québec did not take on any obligation to provide power for 20 of the 24 months covered.
This pullback is likely due, at least in part, to ongoing abnormally dry and drought conditions in much of Quebec, which mean less water flow to power the company’s generators. Hydro-Québec, therefore, faces choices about what to do with the power it can generate, whether that means holding out for higher prices on the New England market or selling it domestically to meet the province’s own growing demand as it too electrifies in pursuit of climate goals.
