**Summary**: Hungary’s PM says the Paks Nuclear Power Plant will reduce output to 240 MW then shut down completely due to critically low Danube water levels. This removes roughly 2 GW of baseload from Central Europe, tightening the regional power market and increasing gas burn and power prices.

## Detail

Hungary’s Prime Minister Péter Magyar announced that, due to further drops in the Danube’s water level, one of the last two generating units at the Paks Nuclear Power Plant will be shut down at 1:30 a.m., cutting the plant’s output to 240 MW before a complete shutdown “for the first time in 44 years.” Paks normally provides around 2 GW of baseload nuclear, covering a large share of Hungary’s electricity demand and feeding into the Central European grid.

The immediate impact is a sudden loss of low-marginal-cost baseload capacity in a landlocked EU member at the height of the summer cooling season. In the very short term, Hungarian and neighboring grids (Austria, Slovakia, potentially Romania and Croatia) will have to replace that nuclear energy with a mix of (1) increased imports from surrounding markets, (2) higher utilization of domestic gas-fired generation, and (3) coal or oil-fired peakers where available. Given the interconnected nature of Continental European power markets, the marginal replacement fuel is predominantly natural gas.

This shock increases regional gas demand at the margin, particularly for power generation, and will add upward pressure to CEE and broader European power prices. While the absolute volume is modest in the context of total EU gas demand, the effect can still move regional gas and power benchmarks by more than 1% because it tightens an already weather-sensitive summer balance and underscores vulnerability of river-cooled plants during droughts. Traders will also price in a higher probability that similar constraints could hit other river-dependent plants along the Danube and Rhine systems if drought conditions persist.

Historically, low river levels in Europe (e.g., 2018, 2022) have contributed to spikes in power prices and episodic strength in European gas benchmarks, especially when coinciding with heatwaves. The current development is likely to support TTF and CEE hub prices over the coming days to weeks, with the duration dependent on hydrological recovery in the Danube basin. Structurally, it reinforces the narrative of climate-related reliability risk for nuclear and thermal plants reliant on river cooling, a medium-term bullish factor for both gas and flexible renewables-backed capacity.
