We produce heat, electricity and cooling in power plants and heating plants in different parts of Helsinki. Find out about the power plants and their production outputs.
Vuosaari power plants
The Vuosaari combined cycle power plants produce a major part of electricity and district heat in Helsinki. Thanks to combined cycle technology, the efficiency of the plants is up to 93%. The power plants use natural gas as fuel.
Hanasaari power plant
During the 2022–2023 heating period, the Hanasaari power plant will be switching to backup use. The Hanasaari coal-fired power plant will cease operations by 1 April 2023.
Salmisaari power plant
The Salmisaari power plant produces heat and power from hard coal and wood pellets. A reception, storage and feeding system for pellets was built at the plant in order to increase the amount of renewable energy.
Heating plants located in various parts of Helsinki guarantee a sufficient heat supply during extremely cold weather, in power plant fault situations and during maintenance outages.
Katri Vala heating and cooling plant
Katri Vala is the largest heat pump plant in the world to produce heat and cooling. Its carbon dioxide emissions are over 80 per cent lower than, e.g. in separate heat production using heavy fuel oil.
Kellosaari stand-by power plant
The Kellosaari reserve power plant ensures sufficient electricity supply in Finland, especially in Helsinki. It is in operation rarely, and only for a short duration at a time.
Kivikko solar power plant
Finland’s biggest solar power plant on completion, the Kivikko solar power plant started operations in April 2016. Its annual production is approximately 700 megawatt-hours, which corresponds to the annual consumption of 350 one-bedroom apartments. You can monitor solar power production in real time on the power plant’s website.
Messukeskus solar power plant
In December 2019 a solar power plant consisting of 1,913 panels was completed on the roof of the Messukeskus Expo and Convention Centre. The output of the panels is 315 W. The average annual production of one panel corresponds to 14 per cent of the electricity consumed by a one-bedroom apartment.
