US EditionFour small modular reactors at Darlington to cost $21 billion to build
- Ontario Power Generation announced in 2025 plans to build four small modular BWRX-300 reactors at Darlington Nuclear Generating Station east of Toronto.
- The project responds to a 75% expected rise in electricity demand by 2050 and follows an April construction licence approval from the Canadian Nuclear Safety Commission.
- The first reactor will cost $6.1 billion, with $1.6 billion for common infrastructure shared by three later reactors, summing to $20.9 billion including contingencies and interest.
- Officials project that electricity generated by the quartet of reactors will cost approximately 14.9 cents per kWh, with OPG financing the entire project internally without relying on government funding.
- The high costs exceed usual targets needed for broad small modular reactor adoption, indicating that final expenses will influence the global interest in SMR development.

Breaking News, Sports, Manitoba, Canada
The government of the Canadian province of Ontario, as the owner of Ontario Power Generation, has made an investment decision to build the first BWRX-300 reactor at the Darlington nuclear power plant. It is to cost 6.1 billion dollars, or 20 million dollars per MW. In addition, there is 1.6 billion for the infrastructure necessary to service 4 such units, because that is how many are to be built in Darlington. So, at the beginning, it is 7.7 bil…
Four small modular reactors at Darlington to cost $21 billion to build – 105.9 The Region
Ontario is set to spend nearly $21 billion to build four small modular reactors east of Toronto. Officials say construction on the first modular reactor at the site of the Darlington Nuclear Generating Station will begin this year and should be completed by 2030. The Canadian Nuclear Safety Commission approved Ontario Power Generation’s plan last month to build the first of four reactors at the site in Bowmanville, Ont. The Independent Electrici…
