SALES OF ELECTRIC ENERGY GREW BY 5,3 PER CENT
The average temperature in 2019 was 9.7 per cent higher than the average year and 2.2 per cent warmer than 2018.
We sold 1,496 million kilowatt-hours (gigawatt-hours) of electricity, 468 gigawatt-hours of district heat and 183 gigawatt-hours of natural gas.
The sale of electric energy grew by 5.3 per cent, the sale of district heat stayed at the same level as the previous year.
84,8 per cent of electricity and 77,6 per cent of heat was produced from renewable energy sources.
A total of 325 gigawatt-hours of electricity was produced at our own power plants and jointly owned power plants. 84,8 per cent of which was produced from renewable energy sources. The Nordic water reservoirs were lesser than in an average hydrological year all the way until the latter part of the year.
We produced 441 gigawatt-hours of district heat in our own power plants and heating plants, accounting for 94 per cent of heat procurement. As much as 85 per cent of district heat was produced energy-efficiently in combined heat and power production. In heat production, renewable energy sources accounted for 77,6 per cent, which was double the national average.
In 2019, carbon dioxide emissions from energy production totalled 28,614 tonnes.
Security of supply remained excellent
The average duration of disturbances in the electricity network and interruptions in the power supply was as low as 0,33 hours in 2019. The average customer-specific outage time in the district heat supply was 0,44 hours.
Weatherproof lines constitute 61 per cent of the electricity network.
