Role in energy production
Electricity and heat production
Pohjolan Voima produces electricity and heat for its shareholders on an at-cost basis. In 2018, Pohjolan Voima’s electricity production was 12.0 TWh. Our share of all electricity produced in Finland was 18%. Heat production totalled 4.4 TWh.
Pohjolan Voima’s total electricity production capacity was 2,704 MW at the end of 2018. Its share was about 16% of Finland’s total electricity production capacity. Heat production capacity was 1,472 MW. The total electricity production capacity includes the capacity of PVO-Lämpövoima Oy’s condensing power plants (477 MW), where production activities have ceased, and the production share of the Meri-Pori plant that was sold at the turn of the year (146 MW).
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 2018, a total of 1.5 TWh of electricity was produced using hydropower. The hydropower production volume remained slightly below the normal level due to the dry summer.
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 its thermal power production, Pohjolan Voima's total capacity was 1,243 MW, of which 620 MW was combined heat and power production and 623 MW was condensing power production. The condensing power production capacity includes the capacity of PVO-Lämpövoima Oy’s condensing power plants (477 MW), which were in production operation until the end of 2015, and the production share of the Meri-Pori plant that was sold at the end of 2018 (146 MW). Pohjolan Voima’s share of the Seinäjoki power plant (63 MW) was sold in March 2018.
The combined heat and power plants produce district heat and process steam for local industry and communities, as well as electricity. In 2018, the heat output of the combined heat and power plants was 4.4 TWh and the electricity output was 2.1 TWh. The condensing power plants produced 0.4 TWh of electricity. Electricity production in the entire thermal power production segment increased from the previous year due to higher market prices.
In 2018, our thermal power plants consumed 4.8 TWh of wood-based fuels, 2.4 TWh of coal, 1.9 TWh of peat and 0.6 TWh of recycled fuel. Oil is used as startup and backup fuel.
Nuclear power production
Teollisuuden Voima Oyj (TVO), a joint venture partially owned by Pohjolan Voima, operates a nuclear power plant in Olkiluoto, Eurajoki. The combined output of the nuclear power plant’s two plant units is 1,780 MW.
Overall, the production year of the Olkiluoto nuclear power plant was good. The capacity factor was lowered by unplanned production interruptions of the OL2 plant unit and major modifications and repairs carried out in connection with the annual outage of the OL1 plant unit. Due to the modifications, the rated output of the OL1 plant unit increased to 890 MW at the turn of the year (from 880 MW). Total production volume of the entire power plant last year was 14.1 TWh. Pohjolan Voima’s share of the production amounted to 8.0 TWh. The average capacity factor of the plant units was 91.1%.
