Finland has 185 power plants in this atlas, with 11,797 MW of reported capacity. The largest listed plant is Olkiluoto 1 (1,760 MW, nuclear; current status unverified). By number of records the most common technologies are hydro, biomass and gas. Grid operators listed here include Fingrid. Electricity is regulated by Energy Authority. Renewables supplied 55.9% of its electricity in 2024.
Reported capacity is the rated size of the listed installations, not electricity being produced now. Source dates and coverage differ, so newer facilities may be absent and historical records may remain.
Grid operators and electricity market in Finland
Liberalised marketCompetitive generation and retail
Nuclear (including Olkiluoto 3), hydro, wind and biomass supply the grid. Electricity is traded through Nord Pool and many households have hourly-priced contracts.
Part of the Nordic synchronous area shared by Norway, Sweden, Finland and eastern Denmark, with a common power exchange across the region.
What does “Liberalised market” mean?
Generators sell into a wholesale market, an independent operator runs the transmission grid, and households can choose their electricity supplier. Networks stay regulated monopolies because building parallel power lines makes no sense.
