Role in energy production
Electricity and heat production
Pohjolan Voima produces electricity and heat for its shareholders on an at-cost basis. In 2019, Pohjolan Voima’s electricity production was 11.7 TWh. Our share of all electricity produced in Finland was 17%. Heat production totalled 4.2 TWh.
Pohjolan Voima’s total electricity production capacity was 2,323MW at the end of 2019. Its share was about 13% of Finland’s total electricity production capacity. Heat production capacity was 1,472 MW. The total electricity production capacity includes the capacity of the Kristiinankaupunki condensing power plant (242 MW), which is no longer in production operation. The Tahkoluoto condensing power plant and the production share of the Meri-Pori condensing power plant are no longer included in the electricity production capacity. Demolition of the former started in 2019 and the latter was sold at the turn of 2019.
Pohjolan Voima partially or fully owns a total of 12 hydropower plants located along the Iijoki, Kemijoki, Kokemäenjoki and Tengeliönjoki rivers. The combined electricity generation capacity of these plants is 541 MW, of which Pohjolan Voima’s share is 449 MW.
In 2019, we produced a total of 1.6 TWh of electricity with hydropower. The production of hydropower slightly increased from the previous year and was close to the production volume of a normal year in terms of water conditions.
The power plants are in good condition and their energy efficiency is excellent due to the recent restorations. Over the past few years, Pohjolan Voima has invested approximately €60 million in the restoration of hydropower plants and hydropower capacity increases.
Thermal power production
In 2019, Pohjolan Voima produced 4.2 TWh of heat. We produce heat at our combined heat and power plants, the total heat production capacity of which was 1,472 MW. Our combined heat and power plants produce process heat and district heat for local industry and communities, as well as electricity.
In addition to heat, the combined heat and power plants produced electricity. In thermal power production, we utilised the heat production capacity and a total of 862 MW of electricity production capacity, of which 620 MW was combined heat and power production and 242 MW condensing power production. In 2019, the electricity output of the combined heat and power plants was 1.7 TWh. No electricity was produced by means of condensing power production in 2019.
The condensing power production capacity includes the capacity of the Kristiinankaupunki condensing power plant (242 MW), which is no longer in production operation. The Tahkoluoto condensing power plant and the production share of the Meri-Pori condensing power plant are no longer included in the electricity production capacity. Demolition of the former started in 2019 and the latter was sold at the turn of 2019. Pohjolan Voima does not have any current condensing power production.
In 2019, we used 4.7 TWh of wood-based fuels, 0.6 TWh of recycled fuels, 1.5 TWh of peat and 0.7 TWh of coal in the combined heat and power production. Oil and natural gas are used as startup and backup fuels.
Nuclear power production
Teollisuuden Voima Oyj (TVO), a joint venture partially owned by Pohjolan Voima, operates a nuclear power plant at Olkiluoto in Eurajoki. The combined output of the nuclear power plant’s two plant units is 1,780 MW.
Total production volume of the Olkiluoto power plant was 14.8 TWh. Pohjolan Voima’s share of the production amounted to 8.4 TWh. The Olkiluoto nuclear power plant had the second best year of its history in terms of production. The OL1 plant unit reached the best result ever, and its capacity factor was 96.9%. The capacity factor of the OL2 plant unit was 92.7%.
