Overview of shares of indvidual electricity sources

CO₂ emission 2023

 
In 2023, HEP's thermal and cogeneration power plants released  2,786,418  t CO₂ during the process of electricity generation.

CO₂ emission intensity for electricity generated by HEP's thermal and cogeneration power plants in 2023 amounted to 184 g CO₂/kWh.

CO₂ emission intensity for electricity generated by a generation mix of HEP sources  in 2023 amounted to 133 g CO₂/kWh.

 
The volume of low and intermediate level radioactive waste per kWh for 2024

NE Krško d.o.o. (Krško nuclear power plant), co-owned by HEP d.d. and GEN Energija (50%:50%) operates in the Republic of Slovenia.
Hrvatska elektroprivreda is entitled to 50% of its net annual electricity production.

Electricity generation in 2024 at the threshold of NPP Krško: 5,551,247 MWh
From 1 January 2024 to 31 December 2024 216 low- and intermediate-level radioactive waste packages were stored with the volume of 97.1 m3 and net weight of 74,637 kg.
Low-and intermediate-level radioactive waste (volume): 97.1 m3 / 5,551,247  MWh   (el) = 1.749 * 10-8 m3/kWh(el)
Net low- and intermediate-level radioactive waste (net weight): 74,637 kg / 5,551,247  MWh(el) = 13,449*10-6 kg/kWh(el) or 13,449 µg/kWh(el)
High-level radioactive waste – spent fuel – replacement of 53 fuel elements in 2024 = 48.7 t U *53/121 element in the core = 21,331.4 kg U
High-level radioactive waste: 21,331.4 kg U / 5,551,247 MWh(el) = 3.84 * 10-6 kgU/kWh(el)
