The jointly owned Krsko nuclear power plant generated 457,822 MWh of net electricity in August, according to published figures. Output was 8.44% below the plant’s monthly production plan. The facility had targeted 500,000 MWh for the month.
For comparison, in August 2025 the plant produced 505,322 MWh. That level was about 1.06% above the same planned monthly benchmark. Despite the August shortfall versus plan, Krsko reported no technical problems.
Operations and reported availability at 100%
Krsko said it operated within its technical specifications during the month. The plant also reported that all safety systems remained functional. Both availability and capacity factors were recorded at 100%.
The operator’s figures show full availability alongside lower-than-planned output. That combination indicates the shortfall was not caused by an outage, although the published data did not specify the underlying operational reason. The August gap amounted to more than 42,000 MWh against plan.
Implications for Slovenia and Croatia power balancing
Krsko is equally owned by Slovenia and Croatia. It is described as a major source of low-carbon baseload electricity for both countries. Changes in output can affect import requirements when hydroelectric conditions are weak or when regional spot prices are elevated.
The August underperformance was framed as manageable for a single month. However, sustained deviations would be relevant for procurement strategies in both markets as they prepare for higher-demand winter conditions.
