Producer of electricity and heat

At the end of 2025, Pohjolan Voima´s total electricity production capacity was 2,889 MW. Our total heat production capacity was 1,089 MW. We produce electrcity and heat at cost price to our shareholders with reliable and adjustable hydroelectric, thermal and nuclear power that ensures security of supply.

Pohjolan Voima’s electricity production amounted to 16.1 TWh and heat production to 2.4 TWh in 2025

In 2025, 99.7% of our electricity production and 91.4% of our heat production was carbon neutral. Production forms in Pohjolan Voima’s portfolio that are considered to be carbon neutral are hydropower and nuclear power, as well as electricity and heat produced with carbon-neutral wood-based fuels and the bio-share of solid recovered fuels (60%, the share used by Statistcs Finland) in thermal power plants.

In 2025, Pohjolan Voima’s total electricity supply was 16.5 (16.4) TWh. Nuclear power made up 82.3% (81.8%) of the electricity supply. Teollisuuden Voima’s Olkiluoto nuclear power plant generated 23.4 (23.3) TWh of electricity, of which Pohjolan Voima obtained 13.6 (13.6) TWh in accordance with its shareholding. The capacity factors of the Olkiluoto 1 and 2 plant units were 96.2% and 71.2% (89.2% and 84.9%), while OL3’s capacity factor was 75.5% (70.4%). The production volumes of the Olkiluoto nuclear power plant were affected by the annual outages of the units and a rotor fault in Olkiluoto 2. Purchases from the Nordic electricity markets were 0.4 (0.3) TWh, and sales amounted to 0.3 (0.2) TWh.

Hydropower accounted for 2.0 (1.8) TWh, or 11.9% (11.1%) of the electricity supply. Hydropower production exceeded that of an average year. A total of 0.6 (0.7) TWh of electricity was produced by combined heat and power (CHP) plants. Their share of the total supply was 3.3% (4.1%).
