Nuclear Heatwave Shock: Hungary is preparing for “the most critical five days” as record-low Danube water forces Paks, its only nuclear plant, to run at reduced output and then shut down completely for the first time in 44 years, raising blackouts and grid strain risks. Grid Emergency Measures: Hungary has so far avoided mandatory curbs on big industry thanks to voluntary savings, but emergency rules now allow disconnections if demand cuts aren’t met. Oil Price Slide on Iran Hopes: Oil tumbled after Donald Trump said “disastrous” Iran strikes were called off and talks are set to begin, pulling Brent and WTI sharply lower and lifting European stocks. EU Sanctions Enforcement at Sea: An EU naval mission boarded a Russian-linked “shadow fleet” tanker in the Mediterranean after flag checks failed, seizing documents while letting it continue—another pressure point on sanctions evasion. Renewables Deal-Making: TotalEnergies agreed to buy Shell’s European onshore renewables business (about 4 GW across Italy, Netherlands, UK and more), while also selling part of its own renewables portfolio to KKR. Tech + Energy Demand Link: The EU launched a tender for up to seven AI “gigafactories,” backed by up to €10bn, aiming for energy-efficient data centres and more European AI computing capacity. Heatwave Across Central Europe: Extreme temperatures near 40C are moving east, with drought disrupting hydropower and power supply planning in multiple countries.
