New York imports more electricity from Canada after high-voltage transmission line opens

A new high-voltage power line between Québec and New York City, called the Champlain Hudson Power Express, is now sending more Canadian electricity into New York's grid. On July 3, 2026, New York's grid operator imported 52 gigawatt-hours from Canada, the most since January 2025, as a heat wave pushed electricity demand up across the state. That day, Canadian power covered 9% of New York's electricity needs, with the new line running at its full capacity of 1,250 megawatts.

The line finished construction and started regular operation in May, after three years of building. New York's energy agency expects it to eventually supply up to 20% of New York City's power. But it hasn't run without trouble: the line went offline for repairs in June, and again on July 4, just a day after helping the grid through the heat wave.

For homeowners, this is mostly background news about where the region's electricity comes from, not something requiring any action. But it does matter for anyone thinking about the reliability and cleanliness of the power grid: more hydropower from Canada, when the line works, means more low-carbon electricity available during hot-weather demand spikes. New York and New England had been relying less on Canadian hydropower in recent years because drought reduced Québec's water levels, but new transmission lines like this one are built to take advantage of hydropower if and when it becomes more plentiful again.
