New nuclear construction for Finland-based power company Fortum “could be a solution in the second half of 2030s, if market, financing and regulatory conditions are right,” a spokesperson for the company has said.

“Our plan is to collaborate with selected plant suppliers to recognise and control project risks before we would consider an investment,” company spokesperson Mark Autio said.

Autio noted that Fortum had begun a nuclear feasibility study in October 2022. The study, which concluded in March 2025, said new nuclear can play an important role in a resilient and competitive low-carbon Nordic power system, but added that an economically viable new-build project will require visibility on income, a solid financing framework and technology-neutral treatment in regulation, Fortum has said.
