The jointly owned Krsko nuclear power plant produced 457,822 MWh of net electricity in August, according to published figures. Output was 8.44% below the plant’s monthly production plan. The plan called for 500,000 MWh for the month.
In August 2025, the plant generated 505,322 MWh, which was about 1.06% above the same planned monthly level. Despite the gap versus plan, Krsko reported no technical problems during the period. The plant operated within its technical specifications and kept all safety systems functional.
Availability and capacity factors were both reported at 100%. With full availability alongside lower-than-planned output, Krsko said the shortfall was not linked to an outage. The published data did not specify the underlying operational reason for the lower production.
Market relevance for Slovenia and Croatia
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 its generation can affect import requirements when hydroelectric conditions are weak or when regional spot prices are elevated.
The August shortfall against plan amounted to more than 42,000 MWh. While that level of deviation is manageable for a single month, sustained underperformance would be relevant for procurement planning in both markets. This comes as preparations continue for the higher-demand winter season.
