Where does our electricity come from?

At this page you will find information about the origin of the electricity we sell and as our customer, also energy sources used under your contract. 

You can influence the origin of electricity you purchase and have your contract as fossil-free electricity, renewable electricity or electricity certified with the EKOenergy label from Suomen luonnonsuojeluliitto.

Origin of electricity

In our product description, we give the origin, production methods, and environmental impact of the electricity we sell. Our product description is based on the law on the certification and disclosure of the origin of electricity, and follows the guidelines provided by Energiavirasto. Energy sources are divided into three categories: fossil energy sources and peat, nuclear power, and renewable energy sources.

Lumme Energia's 2024 product description

Energy sources of sold electricity 4 458 GWh *)

In 2024, specific CO2 emissions, i.e., the ratio of carbon dioxide emissions to sold electricity, from the electricity we sold totalled 290 g/kWh and the amount of nuclear fuel used in the production of electricity in relation to total electricity sold was 0.73 mg/kWh. **)

*) The production mix of sold electricity corresponds to the total production mix defined by Energiavirasto.

**) For the calculation of the total production mix and emission data, we used the national residual mix published by Energiavirasto to take account of the share of sales not certified with guarantees of origin. The energy source and production method-specific residual mix emission factors and the emission distribution method used in connection with co-production are available in the residual mix document published by Energiavirasto.
