According to Finnish Energy, more than one-third of the electricity produced in Finland in 2022 came from nuclear energy and less than 20% from hydropower. The shares of biomass and wind energy were slightly smaller than that of hydropower. The share of nuclear energy will increase significantly once the Olkiluoto 3 nuclear power plant unit starts regular electricity production. The share of wind energy increases at a faster rate. Wind energy could cover as much as 50% of Finland's electricity consumption in 2030, according to Anni Mikkonen, Executive Manager of the Finnish Wind Power Association. The share of wind energy could rise to 70%. Finland's electricity transmission system operator Fingrid estimates that wind energy will overtake nuclear energy in 2026 or 2027.
