It’s time to get real and invest in our lowest cost power options, not expensive nuclear pipe dreams
A News Release from the Ontario Clean Air Alliance
Posted May 12th, 2025 on Niagara At Large
This past May 8th the Ford Government announced it is rolling the dice on building four untested, first-of-their-kind nuclear reactors at the Darlington Nuclear Station.
It’s an expensive and risky roll. The government claims these four reactors will cost $20.9 billion and will take 10 years to build. A much more realistic cost estimate based on real-world experience says these reactors will cost at least $27 billion.
Of course, these American-designed reactors will also depend on enriched uranium imports from the United States . So much for sending Donald Trump a message and protecting Canada’s national security.
This May 9th we released a report [https://www.cleanairalliance.org/the-real-cost-of-new-nuclear/] which compares the costs of these never-before-built reactors with much lower cost, safer and more climate effective options such as solar and wind power.
It finds that power from these new nuclear reactors will cost up to 8 times more than power from onshore wind turbines; almost 6 times more than power from solar farms; and up to 2.7 times more than Great Lakes offshore wind power.
That’s according to the highly respected Energy Futures Group [https://energyfuturesgroup.com/], not the nuclear insiders the government is depending on for its estimates.
While they used data from Ontario’s Independent Electricity System Operator (IESO), the Energy Futures Group made realistic estimates about the capital costs of new reactors and their performance based on real-world data that the IESO chose to pass over in favour of assumptions with little grounding in reality.
Why would we spend many, many times more for power from risky reactors rather than doing what the rest of the world is doing and fully develop low-cost renewable power?
Remember, Ontario has not contracted for a single kilowatt-hour of new wind and solar electricity during that last 7 years while use of solar, in particular, has skyrocketed in much of the rest of the world [https://cleantechnica.com/2025/03/26/92-5-of-new-power-capacity-added-worldwide-in-2024-was-from-renewables/].
The Ford Government doesn’t want to talk about the real costs and alternatives to its nuclear fantasy plans. But we can’t afford to live in a fantasy world, especially now. We need to get real about the best way to control energy costs and to protect our province. Splashing out on unproven nuclear reactors is not a good choice when we can save billions with reliable, already available and proven renewable options.
See our report [https://www.cleanairalliance.org/the-real-cost-of-new-nuclear/] for all the fine print on the Energy Futures Group’s calculations. Then tell the Ford Government [https://www.cleanairalliance.org/nuke-costs/] that it’s time to get real and invest in our lowest cost power options, not expensive nuclear pipe dreams.

P.S. We have posted the spreadsheets behind the cost calculations here [https://www.cleanairalliance.org/the-real-cost-of-new-nuclear/] so you can see for yourself that any reasonable way you crunch the numbers, renewables come out way ahead.
