Information about the projects
Suomen Voima is developing projects to build gas-fired power stations in Mussalo, Kotka, and Kapuli, Mäntsälä.
Both the Kotka and Mussalo gas-fired power stations would consist of several gas engines, with a total electrical output of around 40 MW. The projects also allow for possible expansion, in which case the plant’s electrical output would be around 80 MW.
Suomen Voima has entered into preliminary agreements in both locations to lease the necessary premises for the gas-fired power station project, and the projects are at the preliminary planning stage.
We are also actively exploring opportunities to develop other care home places through various models of collaboration.
Mikä on kaasumoottorivoimalaitos?
A gas engine works in the same way as a conventional engine, but it runs on gas. A gas engine power station consists of several gas engines.
The primary fuel for Suomen Voima’s gas-fired power stations is biogas. In addition to biogas, conventional natural gas, e-methane and hydrogen can be used as blended fuels. Furthermore, it is possible to upgrade the plants to run on 100 per cent hydrogen.
Miksi kaasumoottorivoimalaitosta tarvitaan?
The green transition requires the rapid expansion of wind and solar power. As weather-dependent generation fluctuates rapidly depending on weather conditions, flexible and rapidly deployable balancing power is needed alongside it to ensure sufficient electricity supply in all circumstances.
Gas-fired power stations are one of the key solutions to this need, as they can be started up quickly and are easily adjustable. Gas engines enable the integration of renewable energy into the electricity system whilst maintaining a high level of supply reliability. A gas engine power station can also provide a backup power and flexibility solution for, for example, nearby data centres.
Miten Suomen Voiman kaasumoottorivoimalaitoshanke etenee?
The gas-fired power station projects at Mussalo in Kotka and Kapuli in Mäntsälä are at the preliminary design and licensing stage. Negotiations regarding the supply of equipment are also underway.
During autumn 2026, soil surveys, amongst other things, will be carried out at both plant sites.
