Origin of heat

How the heat we sell is produced varies slightly year by year. It depends on factors such as the output of our own power plants, the price of fuels, the market price of electricity and overall energy demand.

Key Flag certified heat

District heat produced in our power plants is Key Flag certified. Buying a Key Flag certified product is always a good choice for you and for Finland. For more information about the Key Flag please see the website at www.avainlippu.fi.
