Ontario's plan for world's largest nuclear station draws cost concerns

Ontario Power Generation has proposed the New Nuclear at Wesleyville Project, a plan for up to 10,000 MW that could begin construction in the 2030s and operate in the 2040s; the Ontario Clean Air Alliance warns the province's nuclear cost estimates are unreliable and has raised concerns about potential fiscal impacts.

Ontario Power Generation has proposed the New Nuclear at Wesleyville Project near Port Hope, Ontario. The plan is described as potentially delivering up to 10,000 megawatts and could begin construction in the 2030s, with operations projected between 2040 and 2048. The proposal would exceed existing plants by capacity and has prompted public discussion about its implications. Much of the public concern reported so far is focused on projected costs and past budget overruns rather than safety. Key points: - OPG announced the New Nuclear at Wesleyville Project with a reported potential capacity of up to 10,000 MW. - The project timeline reported includes possible construction in the 2030s and operation between 2040 and 2048. - The Ontario Clean Air Alliance states the province plans to spend about $400 billion on new nuclear projects and warns of financial risks, recommending investment in offshore wind and solar as alternatives. Summary: Stakeholders have focused discussion on projected costs and the province's broader energy strategy. The report does not specify the next formal approvals or procedural steps for the project. Undetermined at this time.
