**Summary**: Hungary will shut its Paks nuclear power plant within 48 hours due to critically low Danube water levels, temporarily removing roughly half of the country’s electricity supply. This forces rapid substitution toward gas and cross‑border imports, tightening regional power and gas balances and lifting European power and TTF risk premia.

## Detail

Hungary is reportedly shutting down the last operational reactor at its Paks nuclear power plant for the first time in 44 years, citing insufficient Danube river water for cooling. Paks provides around 50% of Hungary’s electricity. A full shutdown, even if temporary, constitutes a major unplanned baseload loss in Central Europe.

The immediate system response will be higher Hungarian reliance on: (1) gas‑fired generation, (2) increased power imports from neighboring states (Slovakia, Austria, Romania, Croatia), and potentially (3) demand‑side curtailments or price‑driven demand destruction if prices spike. Assuming Paks’ net output of roughly 2 GW baseload, Hungary could require an additional 15–25 million cubic meters per day of gas equivalent if the gap is largely met with gas plants, depending on load and efficiency. That is material versus regional spot gas availability, particularly in a tight storage‑refill season.

The knock‑on effect is to tighten the Central/Eastern European power market, lifting day‑ahead and forward electricity prices and marginally increasing demand for pipeline gas and possibly LNG into Europe. The news compounds existing concerns flagged in earlier reports about European power tightness driven by drought and nuclear constraints, reinforcing a structural risk premium for both power and TTF gas into late summer and potentially autumn if river levels stay low.

Historically, low river levels on the Rhine and Danube (e.g., 2018, 2022) have driven multi‑percentage moves in European power and gas prices via cooling constraints and fuel transport issues. A full shutdown of a major nuke like Paks is rarer and more acute, so price sensitivity could be high initially as markets reassess regional balances and interconnector capacities.

Market impact: Bullish for European power prices (Hungary, CEE, and to a lesser extent Germany/Austria) and moderately bullish for TTF and regional gas hubs as extra generation demand appears. The effect is likely to be most pronounced on near‑term (day‑ahead to month‑ahead) contracts, but if authorities indicate an extended outage pending hydrological recovery, the risk premium could extend into Q4. The impact is structural for as long as drought conditions persist and river levels restrict nuclear cooling.
