Poland will build these same models as well, and so too in Ohio.
But this is the first to begin construction.

But this is the first to begin construction.
Construction has begun on the Western world’s first grid-scale Small Modular Reactor (SMR), though small is not what comes to mind, considering that the machine will fit on two soccer fields.
According to AutoNotion, a 953-tonne slab of steel and concrete was lowered into a 35-meter shaft at Ontario’s Darlington New Nuclear Project site, “ending a decade of talk” about the new nuclear technology and ushering in a period of action.
The slab is the base mat of the first BWRX-300 modular plant designed by GE Vernova — formerly GE Hitachi Nuclear Energy. Four units are planned for the site, each with a capacity of 300 megawatts of electricity, enough to power 300,000 homes. By comparison, Darlington’s four conventional nuclear reactors each provide 935 MW.
Ontario government support for the CAD$20.9 billion project came after Ontario Power Generation received a Licence to Construct in April 2025 from the Canadian Nuclear Safety Commission. The first reactor is budgeted for CAD$7.7 billion, which includes $6.1B for the unit and another $1.6B for roads tunnels, cooling-water lines and other infrastructure shared across all four units.
When completed, it will be the first commercial grid-scale SMR in the West, with an in-service target date of 2030. Russia and China already operate Small Modular Reactors, and Argentina has a pilot under construction. According to AutoNotion, the Darlington New Nuclear Project is the first one a G7 country has built and wired to a major grid.
