The jointly owned Slovenian-Croatian Krško nuclear power plant produced 497,404 MWh of net electricity during the reported month, slightly below its 500,000 MWh production target.
Output was around 0.5% below plan, compared with 505,827 MWh during the corresponding previous period, when production exceeded the same target by about 1.2%.
The plant nevertheless reported full technical availability. Both availability and capacity factors were stated at 100%, with no technical problems affecting operation.
Krško remains a critical source of baseload electricity for both Slovenia and Croatia. Its annual production corresponds to roughly 20% of Slovenian electricity consumption and around 16% of Croatian demand, giving relatively small changes in reactor availability an outsized impact on regional balances.
The modest shortfall against the monthly plan therefore did not indicate a mechanical reliability issue.
Attention around Krško has instead increasingly centred on environmental operating constraints during periods of extreme summer heat and low river flows, when cooling requirements can force generation reductions even when the reactor remains technically available.
That distinction is increasingly relevant in European nuclear markets as high summer temperatures expose thermal generation assets to hydrological and cooling-water constraints rather than conventional equipment outages.
