Origin of electricity for corporate customers

Carbon dioxide-free electricity is electricity produced through forms of production that do not emit carbon dioxide into the atmosphere. It is also spoken of as fossil-free electricity production because it does not use fossil fuels such as coal or oil. The electricity of Fortum Carbon Free is currently produced by nuclear power.

Yes, electricity from different origins gets mixed in the electrical grid, so the verification of origin is done computationally. Electricity origin is decoupled from electricity production, and its sales are monitored separately under the Guarantee of Origin system. 

The Guarantee of Origin system offers you, as an electricity user, the possibility to choose renewable electricity. Only electricity that has been issued a guarantee of origin can be sold as renewable.

The Guarantee of Origin system ensures that electricity with the environmental label is generated with renewable energy sources in compliance with Directive 2001/77/EC. The verification is performed per production plant and production time as part of an annual audit conducted by an external auditor.

In the case of nuclear power, the producer guarantees the origin of the electricity. The verification of electricity origin sold by Fortum Carbon Free is carried out by the auditing company Deloitte.

The electricity contracts of small and medium-sized enterprises are entirely CO2-free, which means that the production of electricity does not produce any CO2 emissions. This means that fossil fuels such as coal or oil have not been used in electricity production. Carbon dioxide emissions are a major cause of global warming, and carbon dioxide-free electricity will therefore help in the fight against climate change. The electricity of CO2-free electricity contracts has been produced with nuclear power and hydropower.

If you want CO2-free electricity that is produced with renewable energy, such as hydro, wind or solar power, you can add the Fortum Vihreä additional service to your contract. You can order an electricity contract with the Vihreä additional service for your company effortlessly online or by contacting our customer service.

Since 2022, large companies have been able to fulfil their electricity demand with residual load, which includes nuclear and fossil fuel electricity, and the share of renewable electricity that has not been sold through The Renewable Energy Guarantees of Origin scheme. All our corporate customers, regardless of company size or electricity consumption, can also choose to buy 100% renewable electricity by choosing Fortum Vihreä, which is produced as a combination of hydro, wind and solar power.
