National energy mix

The National Energy Mix represents an overview of the shares of individual energy sources in the total electricity produced and is published on the basis of the obligation of OKTE, as pursuant to Act 251/2012 Coll. 6 letter about). The national energy mix serves the supplier to determine its energy mix (the share of individual sources of electricity in the supply) for that part of electricity that is not substantiated by the applied guarantees of origin in accordance with the relevant regulations.

The supplier may increase the share of one type of resource for a given final customer only if it is proved by the guarantees of origin applied in favor of the given customer.

The national energy mix was determined on the basis of the methodology of the Association of Issuing Bodies ("AIB"), which is available on  the  AIB website . This methodology is used by all participating countries.

The national energy mix below is a preliminary result from data available up to 21 April. The final energy mix will be announced at the turn of June and July.



Renewable resources - total 18.02%
Biomass 5.01%
Sunny 1.78%
Wind 1.72%
Water 8.07%
Geothermal 0.00%
Other renewable 1.44%
Fossil resources - total 26,49%
Coal 6.86%
Brown coal 5.18%
Gas 12.36%
Oil 1.49%
Other fossils 0.60%
Nuclear resources - total 55,49%


The energy mix also includes data on harmful substances (CO 2  and radioactive waste) that arise in the production of electricity from the energy mix.

CO 2  (gCO 2 / kWh) 198.59
Radioactive waste (mg / kWh)      1.90
