Hungary’s Nuclear Plant Stares Down a Drought-Driven Energy Crisis
8/8/2026, 12:16:52 AM
Core Event
Record-low Danube levels have forced Hungary’s sole nuclear facility, the Paks Power Plant, to run at only 10 %–12 % of capacity. As of early August, three of the four reactors were offline, leaving a single turbine generating about 240 MW. The government asked industrial users and households to cut electricity consumption, especially during the 5 p.m.–10 p.m. peak-demand window.
Background & Context
Paks supplies roughly half of Hungary’s electricity. The plant uses once-through cooling from the Danube, and a three-month drought has driven river levels to historic lows—23 cm on 29 July, well below the 33 cm record of 2018. Similar water-stress conditions affect Romania’s Cernavoda plant, which also draws Danube water.
Data & Statistics
- Paks output: ~240 MW (?10 %–12 % of normal 2 GW).
- Voluntary cuts: 600–700 MW, comparable to switching off about 1 million air-conditioners.
- Industrial savings: 60–90 MW from suspended freight rail and cuts by firms such as Mol, Gedeon Richter, Suzuki, Mercedes-Benz, Audi and BMW.
- Household reduction: Estimated 700 MW on a single day.
- Danube flow in Romania: ~1,400 m³/s, about one-third of the typical August average.
Official Statements & Responses
Prime Minister Péter Magyar emphasized “the heatwave will peak today and tomorrow… so voluntary cutbacks … will be especially important between 5 p.m. and 10 p.m.” He warned that “we must find a solution for operating the Paks nuclear plant as the Hungarian economy cannot work without the plant for months.”
The government kept electricity subsidies, pledged EU funds for grid resilience, dimmed decorative lighting on landmarks and cancelled parliamentary sessions to lower demand.
Romanian Prime Minister Ilie Bolojan announced a state of alert for the energy sector and urged voluntary cuts, while plant director Romeo Urjan said sinking four rock-filled barges could extend the remaining reactor’s operation from five-six days to nine-ten days.
On-the-Ground Reports
Residents along Budapest’s Margaret Bridge described the low river as a “wake-up call” to climate change. One resident, Krisztina Nemeth, noted the bare riverbed while wearing a straw hat.
Conflicting Reports & Gaps
Sources differ on Paks’ output: Reuters cites “just over 10 %,” DW reports “around 12 %,” and a Hungarian official mentions “12 % of total output.” Household reduction figures also vary between 600 MW and 700 MW. No definitive data have been released on the feasibility of restarting the three offline turbines.

What’s Next
- Water level outlook: Magyar expects a temporary rise of about 20 cm in the coming days, though no further rain is forecast.
- Potential turbine restart: A “slight chance” exists that a second turbine could be brought online on a Monday, potentially doubling output.
- Policy review: The government plans to renegotiate the Paks 2 expansion and explore alternative cooling methods, including cooling towers.
- Regional coordination: Hungary continues to import electricity, with Ukraine supplying 61 GWh in the last week of July, while Romania proceeds with rock-barrage operations slated for early August.
