Helen, the Finnish utility, is set to invest between €1 billion and €5 billion in Small Modular Reactor (SMR) capacity for heat and cogeneration in Helsinki. The investment amount will vary based on whether the focus is solely on heat production or includes electricity generation.

This initiative reflects a significant shift from theoretical discussions to practical application in urban energy planning. Following the closure of Finland's last coal power plant in 2025, Helen views nuclear energy as a means to enhance capacity and reduce emissions amid rising energy demands driven by electrification and clean tech. Helen is currently in the urban planning phase and aims to select a site by the end of 2027, indicating a move beyond mere strategic exploration.
