Interest in certifying energy from low-emission sources grows in Czechia

Activity in the market for guarantees of origin for electricity, gas and heat in the Czech Republic rose again last year. The number of redeemed guarantees of origin reached 8.8 million, representing a year-on-year increase of 35%. The number of guarantees of origin issued rose by as much as 122%, to more than 13 million. The overwhelming majority (83%) of issued guarantees of origin related to electricity from nuclear power plants. This follows from statistics published by market operator OTE.

Guarantees of origin enable consumers to virtually assign the source of the electricity, gas or heat they consume, thereby making it "greener". For operators of energy facilities that have guarantees of origin issued and subsequently sell them, these certificates represent an additional source of revenue. One guarantee of origin corresponds to 1 MWh of energy supplied.
