Bulgaria's Kozloduy nuclear power plant will reduce capacity at one of its two units by 120 MW starting August 20 due to falling water levels in the Danube River, which are critical for cooling operations. This is the first time in the plant's 52-year history such a reduction has been necessary due to extreme meteorological and hydrological conditions.

This Wire brief sits within Fusion42's coverage of Energy.

◆ The Wire takeaway

Your energy supply plans must now account for climate-induced water shortages that can reduce nuclear plant output. This shift rewrites operational risks for power startups tied to river-dependent cooling.
