**Summary**: Hungary faces critical days as drought threatens nuclear plant shutdown, while Ukraine has begun exporting electricity to Romania to cover drought- and nuclear-related deficits. These developments point to emerging regional power-market tightness and higher price volatility in Central and Eastern Europe.

## Detail

1) What happened:
Reports indicate Hungary is facing “critical days” as severe drought threatens the operation of a nuclear power plant, likely through cooling-water constraints on river levels and temperature. Simultaneously, Ukraine has started selling electricity to Romania, which is dealing with a supply deficit driven by the same drought conditions and large-scale nuclear plant outages.

2) Supply/demand impact:
Hydrological stress and nuclear derating or shutdowns reduce baseload generation capacity in parts of Central and Eastern Europe. To compensate, Romania is already importing from Ukraine, and Hungary may need to increase imports or ramp up thermal generation if nuclear output is curtailed. This shifts marginal generation toward gas- and coal-fired plants, lifting demand for natural gas and, to a lesser extent, coal and carbon allowances. Even moderate nuclear losses can significantly tighten regional power balances, particularly in peak hours, leading to higher spot and forward electricity prices and increased volatility.

3) Affected assets and direction:
Regional power contracts (Hungary, Romania, broader CEE) are biased higher, especially front‑month and quarter products. European natural gas prices (TTF, CEE hubs) may see upside pressure as gas-fired units cover nuclear and hydro shortfalls. EU carbon (EUAs) could also firm as thermal generation share rises. Ukrainian power exports offer some relief but also reflect that Ukraine now has spare capacity and grid stability sufficient to export, which may gradually integrate it more into the European power market price formation.

4) Historical precedent:
Past European droughts that restricted river cooling or hydro output (e.g., 2018, 2022) materially lifted regional power prices and increased gas burn, even without catastrophic nuclear shutdowns. Markets typically repriced front‑end power and gas by several percent over days to weeks as the scale of derating became evident.

5) Duration of impact:
As this is weather- and hydrology-driven, the impact is likely to persist at least through the current drought period—weeks to potentially the rest of the summer—if river conditions fail to improve. Structural climate trends suggest more frequent recurrences, reinforcing a medium‑term premium on flexible generation and regional interconnections, but the current price impact is primarily a short‑ to medium‑term (seasonal) tightening of CEE power and gas markets.
