Green Power

Natural renewable energy from Finland

Vihreävirta (Green Power) is the choice of an aware consumer, since it is produced by using renewable sources of energy in Finland. You have a freedom to decide how your electricity is produced: select wood-based fuels and hydroelectric power, wind power or solar power!

Vihreävirta electricity is produced at the Merikoski, Kolsi, Koivukoski, Korkeakoski, Myllykoski and Vuolenkoski hydro power plants and at the Toppila power plant using wood-based fuels in a combined heat and power generation process.

If you choose wind power as the way of production, the electricity of the contract is produced in the wind farms located in Röyttä (Tornio), Torkkala (Vaasa), and Santavuori (Ilmajoki) among other locations.

Vihreävirta solar power is generated in our solar power plant in Toppila, and by small solar power plants which choose to sell their surplus electricity.
