Hungary is confronting a fresh energy scare as the Paks nuclear plant risks a shutdown within days due to exceptionally low water levels on the Danube. The development is already making waves across Europe news, with officials warning that prolonged drought and heat could put added pressure on power systems across the region.
The Paks facility generates around 2,000 MW and supplies close to half of Hungary’s electricity, making it one of the country’s most critical energy assets. Prime Minister Péter Magyar said a phased and controlled stoppage may be necessary if river conditions do not improve quickly.
Europe news: Why the Paks nuclear plant is under threat
The immediate problem is cooling water. Like many riverside nuclear facilities, Paks relies on the Danube to help regulate reactor temperatures. When water levels drop too far, plant operations become harder to maintain safely and efficiently.
According to Hungarian authorities, the Danube has fallen to an unprecedented low after an intense heatwave and ongoing drought. On Wednesday, the river’s gauge reportedly stood at just 23 centimetres, underlining how severe the situation has become.
Magyar said the full shutdown of the plant could happen very soon if conditions persist. That would be a significant moment for Hungary’s grid, as Paks has previously reduced output during hot summers but has not fully halted operations because of low river levels.
Key facts at a glance
- Paks produces about 2,000 MW of electricity
- The plant supplies nearly 50% of Hungary’s power needs
- Low Danube water levels are threatening reactor cooling capacity
- Another plant, Dunamenti, also lost 400 MW after a malfunction
- Hungary says imports can cover between 3,600 MW and 3,800 MW if needed

Hungary says power supply remains secure
Despite the pressure on domestic generation, the government insists there is no immediate risk to households or businesses. Magyar said Hungary’s electricity import system has enough capacity to stabilise supply if Paks goes offline temporarily.
Officials are also preparing contingency measures in case the drought deepens. These plans would reportedly focus on large industrial and public-sector consumers with heavy electricity demand. Essential services such as hospitals, social care institutions and community providers would be protected.
This is a notable point for readers following irish news and ireland news around European energy resilience: governments are increasingly having to balance grid security, climate risk and industrial demand at the same time.
Danube drought highlights wider regional energy risks
The Paks threat is not an isolated incident. Romania also shut both of its nuclear reactors on 29 July because of the same Danube-related water stress. That raises broader concerns about how extreme weather is affecting energy infrastructure across Central and Eastern Europe.
The crisis also revives debate about Hungary’s long-term energy strategy. Paks uses Russian-built technology, and an expansion deal agreed under the previous government was intended to strengthen energy security. While construction on that expansion began in 2026, the current administration has yet to give a detailed update on where the project now stands.
For energy analysts, the bigger story in Europe news is not just one plant or one country. It is the growing vulnerability of power generation to climate-driven river shortages, rising water temperatures and repeated summer heat extremes.

What happens next?
In the short term, everything depends on Danube conditions and whether cooling operations can continue safely. If the river remains critically low, a scheduled shutdown of Paks looks increasingly likely. Hungary says backup imports and emergency planning should prevent disruption, but the episode is another warning sign for Europe’s climate-exposed power system.
The clear takeaway for Europe news readers is that energy security can no longer be separated from water security. As drought tightens its grip on major rivers, the reliability of nuclear and thermal power stations may face even greater scrutiny in the years ahead.
