300-MW unit connects to grid by 2030

Public utilities lead North American projects

When it comes to advanced nuclear generation, most North American power producers are in the study and development phases. But Ontario Power Generation is currently constructing the first of four small modular nuclear reactors at its Darlington facility, with the first 300-megawatt unit scheduled to complete construction and connect to the grid by 2030. The other three reactors are scheduled to be completed in the mid-2030s, totaling 1,200 MW of firm capacity from advanced nuclear reactors.

In this episode, Dan Testa speaks with OPG President and CEO Nicolle Butcher, from the sidelines of the CERAWeek by S&P Global conference in Houston, about the state of the advanced nuclear project so far, how OPG selected this reactor design and why public power providers, like OPG in Canada and the Tennessee Valley Authority in the US, are taking the first steps to build advanced nuclear generation in North America.
