Bulgaria's Energy Experts Say Renewables and Coal Plants Can Offset Potential Kozloduy Nuclear Shutdown

Renewable energy specialist Nikola Gazdov explained that Bulgaria’s current electricity generation, about 7,000 MW, far exceeds its consumption of roughly 3,800 MW, meaning the grid could remain fully supplied even if the Kozloduy nuclear power plant were to cease operations. He highlighted the role of photovoltaic centres, battery storage – capable of holding over 15,000 MWh and delivering up to 5,000 MW for several hours – and a diversified mix of generation sources in preventing any power deficit. Gazdov noted that Bulgaria is among the European leaders in battery installations.

Energy analyst Ivan Hinovski warned that the cooling system of Kozloduy depends on the Danube’s water level, which has been falling. He said a continued drop could force a shutdown of one reactor block within one to two weeks if the river falls below critical levels. Hinovski stressed that coal‑fired plants, especially Bobov Dol and Maritsa East 2, are essential to maintain balance in the national power system and urged the energy minister to ready these thermal stations as a backup.

Both experts agree that a combination of renewables, battery storage, and existing thermal power capacity is crucial for Bulgaria’s energy security amid the regional electricity crisis.
