The Canadian Wildfires Ominously Messed Up a Clean Energy Power Line

The Quebec forest fires that have recently contributed to some of the worst smoke days in American history are also wreaking minor havoc on the electric grid.

Observers of electricity markets were puzzled Wednesday evening when grid operator ISO-New England announced that “due to an unanticipated transmission outage and higher-than-forecast consumer demand,” the New England grid would be calling on reserves “to balance the regional power system.” Demand that day did not seem particularly or unexpectedly high, nor were there any obvious supply issues in New England, so why was ISO-NE having trouble? More illumination came Thursday, when it specified there was a transmission issue with its imported power.

A spokesperson for Hydro-Québec, the French Canadian utility, told me that its Phase-2 power line, which connects the vast amounts of hydropower generated in northeastern Canada to a substation over 900 miles away in Boston, went down briefly yesterday due to forest fires in the James Bay region. “Heat and smoke can trigger automated system protection mechanisms, which will essentially shut down the powerline in order to protect it,” the spokesperson said. These are many of the same fires that have recently blanketed the eastern and midwestern United States in smoke.

Imported hydropower from Quebec plays a crucial role in New England’s grid, responsible for over 11% of the region’s total electric use in 2022. New York is also looking to expand its use of imported hydropower, with a new transmission line that will run from the Canadian border to New York City and is currently under construction.

Quebec itself essentially powers its entire grid with its massive hydropower resources, making it one of the least carbon intensive grids in the industrialized world.

Some of that excess hydropower has been exported to New England for decades, and it has become more and more attractive south of the border as New England and New York seek to decarbonize.

The actual scale of the disruption in power delivery turned out to be well within ISO-NE’s capabilities to manage. The grid operator didn’t ask consumers to use less power, as Texas did in the past few weeks when its grid was beset by high temperatures and record consumer demand, or as New York and California have done on hot days. But in addition to pulling in more imports from New York state, ISO-NE also had to burn oil for electricity, which New England sometimes does when its natural gas supply runs short, especially in the winter when gas is used for heat.

While the system in both Quebec and New England survived the transmission hiccup — a Hydro-Québec spokesperson made sure to note that “our bulk transmission infrastructure has not suffered any damage as a result of the forest fires” — it does underscore the threat that even non-carbon-emitting electricity generation faces from the effects of climate change. In addition to briefly shutting off this transmission line, forest fires have also reduced solar generation due to blocking out the sun.

On the other hand, as Joe LaRusso of the Acadia Center, a New England clean energy group, pointed out to me, transmission is also what saved the day when Quebec’s imports were shut off, as imports from New York picked up the slack. “It serves as a demonstration not that transmission is a weak link, but that it’s the principle means of enabling balancing authorities like ISO-NE and NYISO to rely on one another to make up for variations in capacity.” That’s as true of “unplanned generator and transmission outages” as was the case in Quebec, as it is for more predictable fluctuations in solar and wind power.

“While forest fires are not a new phenomenon, the intensity and increased frequency of these events in North America are the result of climate change,” the Hydro-Québec spokesperson said. “The amplitude of this event should serve as a clear reminder that we need to accelerate every effort towards transitioning away from the burning of fossil fuels for electricity generation.”

Hawaii’s Electricity Bills Spiked 22% in May

The latest update to the Electricity Price Hub shows a price increase in line with what regulators predicted.

Hawaii already had the most expensive electricity in the country. Then the war in Iran happened.

America’s 50th state has no domestic fossil fuel industry and no access to the continental United States’ natural gas pipeline network, and is therefore uniquely dependent on imported oil to generate electricity. (The state’s last coal plant shut down in 2022.)

AI IPOs Could Create a Wave of New Funding for Climate Tech

All that cash has to go somewhere. Why not philanthropic funding for decarbonization?

Artificial intelligence models — and the infrastructure to support them — have kept the U.S. economy afloat amidst a turbulent year of tariffs, war, and energy price volatility. Nvidia, the dominant supplier of high-end AI chips, is now the world’s most valuable company. Leading AI firm Anthropic has filed to go public, while reporting indicates that OpenAI will soon follow suit. SpaceX, which is betting heavily on orbital data centers, is also going public this month, in what analysts expect will be the largest IPO in history.

All of which is to say that a lot of people have already become very, very rich from the AI boom, with many more poised to do so very soon. That will almost certainly lead to a wave of philanthropic capital in search of worthy causes. AI safety will obviously be a priority. But given growing concerns over AI’s power needs, reliance on fossil fuel infrastructure, water consumption, and effect on electricity prices, it seems likely that climate and clean energy will become top priorities for newly minted AI billionaires, as well.

Current conditions: Des Moines, Iowa, is bracing for thunderstorms through Thursday night • Temperatures in Touggourt, in northern Algeria, are soaring north of 103 degrees Fahrenheit • European forecasters expect the brewing El Niño conditions forming now could become the strongest ever recorded.


THE TOP FIVE

1. Federal court tosses out Trump’s strict limits on solar and wind tax credits

Last August, the Internal Revenue Service issued strict new rules for solar and wind developers hoping to tap the federal tax credits known as 45Y, for the production of carbon-free electricity, and 48E, for investment in green generating assets. For years, the U.S. government had required companies to invest 5% of the total cost of the project by a certain deadline to qualify for the rebates. But last summer, the Trump administration eliminated the 5% threshold and instead mandated that projects over 1.5 megawatts in capacity show evidence that physical construction has begun to be eligible for the writeoffs. In all, the new rules “could have been so much worse,” Heatmap’s Emily Pontecorvo wrote at the time. But requiring construction to start narrowed the scope of how many turbines and panels could be built before the two tax credits are phased out this July 4. With less than a month to go before the credits go away, a federal court has intervened to restore the original 5% rules. On Saturday, the U.S. District Court for the District of Columbia overturned the Internal Revenue Service’s strict new rules. The decision found that the Trump administration had repeatedly failed to back up its justifications for eliminating the 5% provision, consider reasonable alternatives, or demonstrate that the policy change wasn’t motivated by discriminatory views of the wind and solar sectors. “Evidence in the record leaves substantial doubt that the proffered explanation sincerely accounts for the agency’s decision,” the ruling reads. “A thorough review of the record undercuts the conclusion that the defendants made a reasoned decision to eliminate the 5% safe harbor for wind and large-scale solar projects based on concerns about stockpiling.”
