Slovenia’s Krško nuclear power plant generated 5.547 TWh of electricity in 2025, slightly above plan, according to its annual report. The report also shows the plant recorded revenue of €240 million, up €13 million year-on-year. Availability and capacity factors remained above 91% during the year.
Financial results and operating performance in 2025
The annual report attributes the strong operational performance to availability and capacity factors staying above 91%. Revenue reached €240 million, with a year-on-year increase of €13 million. The figures were reported alongside the plant’s electricity generation of 5.547 TWh for 2025.
Refuelling outage and generation outlook for 2026
A scheduled refueling and maintenance outage was completed in the autumn, allowing the unit to begin a new 18-month operating cycle. With no major outage planned for 2026, plant management expects higher output this year. The company is targeting more than 6 TWh of generation, assuming stable operations and no unplanned disruptions.
Cooling constraints and cost pressures
The company said summer restrictions tied to Sava River water temperature remain a potential operational constraint. The restrictions can limit cooling capacity during high-temperature periods. It also noted that rising costs for nuclear equipment, materials, and services are continuing to pressure operating expenses across the sector.
Feasibility study for extending operating lifetime
The Krško nuclear plant is preparing a feasibility study on extending its operating lifetime from 60 to 80 years. Completion is expected later this year. The study is part of assessing long-term nuclear generation strategy in Slovenia.
