GEN, the Slovenian state-owned energy group, earned almost €160 million in 2025. The company said its generation output exceeded plan while it continued investment across its nuclear and renewable portfolio. GEN’s power plants produced 3,427.7 GWh during the year.
Total capital expenditure across GEN’s generation assets exceeded €107.5 million. Roughly half of that spending was directed to maintenance and upgrades of existing facilities. Additional investment focused on the Krsko nuclear plant and related development work.
Spending on Krsko and second-unit development
Around €39.6 million was invested at the Krsko nuclear plant in 2025. The outlay covered dry spent-fuel storage, process information systems and technical security improvements. GEN also continued development work for a proposed second Krsko nuclear unit.
Spending related to the second-unit project reached €10.5 million last year. Technical feasibility work prepared by EDF and Westinghouse was completed, while financing structures were also reviewed. The Slovenian government then approved preparations for the national spatial planning process, moving the project into another formal development stage.
Regional system role and implications for market balance
Slovenia is positioned between the Central European, Italian and western Balkan electricity systems. Krsko already represents one of the largest sources of stable baseload generation in the northern SEE region . A second unit would materially change Slovenia’s future import-export balance.
Before any investment decision can be taken, financing, construction cost and project timing will remain decisive . GEN said the second unit is a long-term option rather than a near-term source of additional capacity. Its relevance to the regional market is described as increasing as development progresses.
