Origin of heat and energy sources

The origin of the heat we sell varies somewhat from year to year. The origin is influenced, for example, by how well our own power plants have produced energy, the price of fuels, and general energy demand.

Our strategic objective is to achieve the net zero target by 2040, in line with the Science Based Targets (SBT) framework. The net zero target replaces our previous goal of achieving carbon neutrality by 2030. Read more about our climate targets here.

In 2024, the energy sources of district heat and steam sold to our customers were divided as follows: 

Energy sources	Own production	Including purchased heat
Peat	8.9 %	8.5 %
Oils	2.6 %	2.5 %
Waste heat	0.1 %	0.1 %
Wood	70.7 %	72.0 %
Other biofuels	0.3 %	0.3 %
Renewable fuels and waste	11.0 %	10.5 %
Electricity	6.6 %	6.2 %

In 2024, 77.7% of the district heat sold to our customers was produced with renewable energy sources.

Other biofuels: plant-based biofuels, excluding wood-based biomass 
Renewable fuels and waste: SRF and demolition wood, municipal waste, and mechanically sorted waste
