Overview of shares of indvidual electricity sources

CO₂ emission

 
In 2022, HEP's thermal and cogeneration power plants released  2.515.554  t CO₂ during the process of electricity generation.

CO₂ emission intensity for electricity generated by HEP's thermal and cogeneration power plants in 2022 amounted to 576 g CO₂/kWh.

CO₂ emission intensity for electricity generated by a generation mix of HEP sources  in 2022 amounted to 132 g CO₂/kWh.

 
The volume of low and intermediate level radioactive waste per kWh for 2022

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 the net annual electricity production.


During 2020, Krško nuclear power plant produced the overall of:

• Electricity generation in 2022 on the threshold of NPP Krško totalled at 5.310.695.133 MWh
• 489 LLW and ILW packages were stored with the volume of 7112,3 m³ and net weight amounting to 51.060,1 kg
• net Low and Intermediate Level Radioactive Waste NSRAO (volume): 112,3 m³ / 5.310.695.133  MWh (el) = 2,114 * 10-8 m³/kWh (el)
• net Low and Intermediate Level Radioactive Waste (NSRAO) (mass): 51.060,1 kg / 5.310.695.133  MWh MWh (el) = 9,614*10^-6 kg/kWh(el) ili 9614 µg/kWh(el)
• High-Level Radioactive Waste (VRAO) – spent fuel – replacement of 56 burning elements in 2022 = 48,7 t U *56/121 element in the core = 22 538,84 kg U
• VRAO:22 538,84 kg U / 5.310.695.133 MWh(el) = 4.24 * 10^-6 kgU/kWh(el)
