A cross-party summit held in January 2024 agreed on the necessity of both renewable and nuclear energy for Slovenia’s carbon-free future.153 A referendum on new nuclear power units due to be held in November 2024 was called off in October that year and may now be held in 2028.
Long-term operation
The Krško nuclear power plant, is a 736 MWe Westinghouse PWR operational since 1981. It is co-owned by Croatia’s Hrvatska Elektroprivreda (HEP) and Slovenia’s GEN Energija and generates about 40% of the country's electricity output.
The unit’s operating lifetime was designed to be 40 years, and a 20-year extension has been approved.
New capacity
Large-scale reactors
A second and possibly third unit at Krško – referred to as the JEK 2 project – is planned. A final investment decision expected by 2028, construction starting in 2032, and completion by 2041. A nationwide referendum on the project due to take place in November 2024 was called off by parliament and is now planned to be held in 2028.
In November 2025 the JEK 2 project company stated that Westinghouse’s AP1000 and EDF’s EPR and EPR1200 reactors had all been judged to be suitable for the JEK 2 site.
Small-scale reactors
In addition to allowing for the expansion of the Krško plant, the national 'spatial strategy' approved by parliament in mid-2023 paves the way for building small modular reactors (SMRs) in the country.
