First it got cold. Across New England, temperatures have been almost constantly below 20 degrees Fahrenheit since last Friday night.
Then it snowed. Winter Storm Fern swept through the region on Sunday and Monday, leaving more than two feet of white stuff in its wake in many places.
But despite the extreme weather, the lights stayed on in the Northeast, for the most part.
At a moment when there is copious debate over how, and how much, to strengthen and expand the New England electric grid, this past weekend functioned as a sort of stress test for the system, highlighting both its strengths and its shortcomings. A closer look at how the grid managed to keep us watching football games and charging our phones offers a few key lessons.
Canada isn’t going to save us
The climate challenges posed by Winter Storm Fern cropped up just a week after the long-awaited New England Clean Energy Connect transmission line started sending hydropower from Quebec into the Northeast U.S. Its purpose: to supply more than 1 gigawatt of power to customers in Massachusetts, providing clean energy and cost savings to the state, which has struck a long-term procurement deal with Canadian energy giant Hydro-Québec.
Last Friday and early Saturday, power flowed as expected. But from Saturday afternoon until Monday afternoon, the exports stopped for all but a few hours on Sunday. Quebec, also experiencing bitter cold, needed the power for its own heating systems. In fact, demand in the province was so high that New England began sending it electricity via a transmission line usually used to bring Canadian power into the U.S.
“There was an expectation that there was a higher quantity and more consistent flows than what happened in practice,” said Dan Dolan, president of the trade group New England Power Generators Association. “The timing of this is certainly drawing a lot of attention, just a week into the commissioning of the project.”
Hydro-Québec didn’t do anything illegal or unethical, Dolan said, and its CEO has indicated the company is prepared to pay the penalties outlined in its contract with Massachusetts for not sending power as obligated. Still, this weekend makes clear that the much-vaunted new transmission line might not do as much to alleviate the region’s energy concerns as had been hoped.
New England needs more generation
As Canadian hydropower stopped coming, New England also had to cope with constrained natural gas supplies. People throughout the region needed the fossil fuel to warm their houses, limiting the supply that was available to power plants and spiking prices. As a result, usually expensive oil generation became the more economical option. Rarely used oil-burning power plants were called into action, producing more than a third of the power flowing onto the grid for some periods. For a sense of scale: Oil-fired generation provided roughly 1% of the region’s power in 2025.
The sudden dependence on one of the dirtiest forms of power supply makes it clear that the region needs to generate more electricity from a wider range of resources, grid experts say. The grid will be more reliable and more economical if it doesn’t have to put so many of its eggs in an expensive, high-emissions basket like oil.
“The cold temperatures and the storm really, really highlight the importance of a portfolio approach,” said Valessa Souter-Kline, managing director of the industry association Advanced Energy United.
