Following severe heat and low Danube water levels that sparked conflicting reports over a full shutdown, the Paksi Atomerőmű’s 2-es blokk continues operating at reduced capacity. Economic and Energy Minister Kapitány István announced a broad modernization program, including simplified solar connections and expanded storage, to secure future energy stability.
The summer heatwave brought unusual strain to Hungary’s energy infrastructure, highlighted by plunging water levels on the Danube. That environmental pressure triggered a sharp public contradiction over the weekend regarding the operational status of the Paksi Atomerőmű. While the facility faced severe cooling challenges, statements from political figures painted starkly different pictures of the plant’s immediate future, leaving the public to parse shifting updates.
Contradictory Signals and the Reality at the Paksi Atomerőmű
Over the weekend, public anxiety peaked when Magyar Péter announced that the Paksi Atomerőmű would completely shut down. The announcement claimed that due to the further decrease of the Danube’s water level, the last-but-one production unit would be switched off at 1:30 AM, leaving the plant producing only 240 megawatts before total shutdown on Sunday, 44 years after its launch.
Yet reality on the ground proved more resilient. Economic and Energy Minister Kapitány István stepped in with a very different assessment, confirming that the country’s energy supply remained stable despite extreme weather conditions. The state-run MVM issued no closure notices, and the plant’s 2-es blokk kept running into Tuesday evening.
Economic and Energy Minister Kapitány István stated via Világgazdaság that block 2 was currently operating at an output of 230 to 240 megawatts, adding that the water level of the Danube had stagnated over the past few hours, which was an encouraging development, and expressing hope that this trend would persist and that there would be no need to shut down the block.
Cooling System Vulnerabilities and the Strategic Value of the Last Turbine
The root cause of the crisis in recent days was not a shortage of water volume in the Danube, but rather the exceptionally low river level threatening the pumps that supply essential cooling water, significantly deteriorating the system’s operating conditions. That operational bottleneck put the facility’s output under intense scrutiny.
Maintaining even a single operating turbine carried immense strategic weight. Beyond contributing the remaining electricity generation to the Paksi Atomerőmű, that running unit provides energy that can be decisive in the subsequent restart of the power plant. A full shutdown makes restarting a complex process that may require external electricity supply, whereas a working turbine helps maintain the system and reconnect other equipment.
Government Response and New Support for Household Solar Systems
Looking past the immediate climate strain, the government launched a comprehensive energy development program aimed at modernizing the electricity grid, expanding energy storage capacities, and accelerating the deployment of renewable energy sources. A central pillar of this initiative targets household consumers: the grid connection process for residential solar systems will become simpler and more transparent.
Economic and Energy Minister Kapitány István stated that their clear objective was to make Hungary’s energy supply even more secure, resilient, and modern, and to ensure that a similar situation would not jeopardize the country’s operation in the future.
The broader upgrade package also emphasizes wind energy investments, a significant increase in both industrial and residential energy storage capacities, and direct benefits for the Hungarian state, local governments, local communities, and families.
Ongoing Precautions as High Temperatures Persist
Even with stabilizing water levels on the Danube and a slowly rising water level during the extraordinary situation, officials emphasize that the emergency has not fully passed. Because the extreme heat persists, the energy ministry continues to urge public caution and voluntary consumption restraint.
Residents are asked to shift the use of high-draw household appliances away from the evening peak hours between 17:00 and 22:00. This conservation effort, paired with the conscious behavior and voluntary consumption reduction of the population and businesses over the past days, played a decisive role in keeping the national power grid in balance while authorities pursued long-term structural fixes.
