Steady Energy is a Finnish nuclear technology developer that designs, constructs, and operates compact nuclear heating plants for carbon-free district heating. Its core technology is the LDR-50, a heat-only small modular reactor that produces up to 50 MW of thermal power at low temperatures and pressures without a turbine or generator. On February 16, 2026, the company began construction of a full-scale, electrically heated LDR-50 pilot in Helsinki to demonstrate safety features ahead of commercial deployment.
