Steady Energy Oy
Profile
Steady Energy, a VTT spin-out, develops the LDR-50, a 50 MWt heat-only district-heating reactor. A STUK-led international joint early review (with SSM, PAA, SUJB and SNRIU) published its closure report on 6 Jul 2026, concluding that the documentation was not yet detailed enough to start formal licensing; a pilot plant is being built inside a decommissioned coal plant in Helsinki and Finnish municipal utilities (Kuopion Energia, Helen and others) hold cooperation or assessment agreements. Private; no market data apply.
