The Finnish nuclear power company Teollisuuden Voima Oyj (TVO) produced 16.4 TWh of electricity in 2022, accounting for about one fifth of the total electricity consumption in Finland, compared to 14.4 TWh in 2021. The company owns and operates the Olkiluoto nuclear plant, which comprises two boiling water reactors (BWRs), each with a capacity of 920 MW, and an European pressurised reactor (EPR), with a nameplate capacity of 1,720 MW. The reactor was connected to the Finnish grid in March 2022, and regular electricity production is scheduled to start in 2023.
In 2020, nuclear accounted for 34% of Finland’s power generation. Fortum owns and operates two Soviet-designed VVER-440 PWR reactors (2x531 MW) at Loviisa. Following the Russian invasion of Ukraine, Fennovoima ended in May 2022 the engineering, procurement, and construction (EPC) contract with RAOS Project, an affiliate of the Russian state-owned nuclear company Rosatom, for the 1.2 GW Hanhikivi 1 nuclear project to be built in Pyhäjoki (northern Finland).
