About
Steady Energy develops the LDR-50, a simplified small modular reactor (SMR) delivering 50 MW of thermal output for zero-carbon district heating. Founded in 2023 as a spin-off from VTT Technical Research Centre of Finland, the company raised €32 million and in February 2026 poured first concrete for a full-scale non-nuclear pilot plant inside Helsinki's former Salmisaari coal power station. Fortum and Finnish energy utility Helen are strategic partners. Steady Energy is also expanding to Sweden, targeting district heating decarbonisation across the Nordic region.
