Energy traces run close to a bridge in Hamilton, Ontario, on Feb. 4. This week, Ontario’s chief threatened a surcharge on Canadian electrical energy offered in some U.S. states in retaliation for President Trump’s tariffs.

For greater than a century, the U.S. and Canada have offered one another electrical energy by way of energy traces that criss-cross the border, an association that has traditionally hummed alongside due to the nice and cozy relationship between the 2 nations. That modified this week.
On Monday, Ontario Premier Doug Ford introduced the province was imposing a 25% surcharge on electrical energy exported to 3 U.S. states: Michigan, Minnesota and New York. The transfer was in response to President Trump’s tariffs on Canada.
Trump, a day later, stated he would double U.S. tariffs on Canadian aluminum and metal to 50%. “Why would our Country allow another Country to supply us with electricity, even for a small area?” Trump requested in a separate submit on his social media website.
In the end either side backed down from their threats and agreed to fulfill to debate commerce points. However the whirlwind episode highlighted the U.S. reliance on imported Canadian energy — and the truth that some states acquire electrical energy from their northern neighbor.
This is what to find out about Canada, the U.S., and the electrical energy that zips throughout the border.
The U.S. and Canada share an influence grid
Greater than 30 main transmission traces join an array of close by U.S. and Canadian cities and areas. The 2 nations even function by the identical set of reliability requirements, regardless of the political boundary between them. A large 2003 blackout lower energy to some 50 million individuals on either side of the border.
“You have cities and urban areas that are close neighbors, and you have electric systems that are close neighbors,” stated Cy McGeady, a fellow on the Middle for Strategic and Worldwide Research. “There’s sort of an imaginary line that runs between them called the border.”
Built-in energy grids have a number of advantages, McGeady says. For one, a bigger system is extra resilient towards disruptions and energy outages.
Electrical energy can be cheaper in built-in grids. Energy mills with the bottom costs will extra simply discover consumers in a bigger electrical system. “There’s a basic economic factor that drives grid integration everywhere,” McGeady stated.
Canada says it exports sufficient electrical energy to the U.S. to energy greater than 5.6 million properties.
Why the U.S. buys electrical energy from Canada
Whereas electrical energy shared throughout the border represents lower than 1% of the overall energy generated by each nations, in response to the U.S. Power Data Administration, the commerce is vital to making sure that electrical provide meets shopper demand.
In 2023, the U.S. purchased $3.2 billion value of electrical energy from Canada, whereas it offered Canada $1.2 billion in electrical energy, in response to U.S. authorities knowledge. U.S. states and areas close to the border — resembling New York, New England, the Midwest and the West Coast — usually purchase essentially the most Canadian electrical energy.
In keeping with Seth Blumsack, an vitality professor at Penn State College, U.S. electrical energy operators possible have sufficient short-term capability to interchange any Canadian energy that’s withheld or turns into too costly to purchase, however it might come from a distinct supply.
“It’s not like if the Canadian hydro imports get cut off, you’re going to replace it with wind and solar in New England,” Blumsack stated. “You’re going to replace that with power plants in New England that are burning natural gas or fuel oil or some other fuel source that is going to increase carbon emissions and may also increase local air pollution.”
States resembling New York and Massachusetts have tried to cut back their carbon emissions partially by shopping for Canadian electrical energy, which is mostly generated by way of hydroelectric energy. Commerce disputes between the 2 nations might complicate these local weather targets.
What occurs if the battle over electrical energy surges
The latest spat over electrical energy gross sales has dimmed the as soon as glowing relationship between the U.S. and Canada, which have each been boosted by the free commerce of energy, stated Asa McKercher, a professor of U.S.-Canada relations at St. Francis Xavier College in Nova Scotia.
“That’s what makes this sort of tariff war really self-defeating for both countries, is the fact that we’ve benefited from access to cheap energy,” he stated.
McKercher stated some Canadians have argued prior to now that the nation ought to export much less of its vitality to the U.S. and as an alternative share it inside its personal borders. These views had usually been dismissed, however extra Canadians are coming round to the thought given Trump’s latest assaults on the nation, he added.
“Now those arguments are sort of returning again, and I think increasing numbers of Canadians are seeing some wisdom in those suggestions,” McKercher stated. “The situation is kind of a reversal of a lot of past history, in which the trend has been towards integration of continental energy resources.”
Within the quick time period, analysts say additional disputes between the U.S. and Canada over electrical energy shared throughout the border will imply increased electrical payments for customers.
“It made economic sense to build these transmission lines and to move power back and forth across the border,” McGeady stated. “If you disrupt that, the impact has to be upward pressure on prices and reduced reliability. That’s what the fundamental risk is here.”
