Hungary ramps up energy‑saving measures as heat wave strains power grid

Hungary heat wave Paks nuclear plant electricity demand energy‑saving measures

A prolonged heat wave in Hungary has pushed daytime temperatures close to 40 °C, prompting the partial shutdown of the Paks nuclear power plant. The loss of capacity has increased stress on the electricity system, especially during the evening peak between 17:00 and 22:00.

Utility operators and public bodies have responded. E.ON Hungária has placed its network on heightened standby, expanded fault‑repair and customer‑service capacity, and coordinated actions with the Ministry of Economy and Energy, MAVIR Zrt. and other sector participants. OPUS TITÁSZ Zrt. has asked large‑scale consumers to curb usage during the 17‑22 hour window and is monitoring load peaks. The National Trade Association (OKSZ) and its member retailers are voluntarily cutting lighting, reducing office air‑conditioning and supporting hybrid work. Magyar Közút announced temporary cuts to bridge illumination and limited use of traffic‑sign lighting, while also restricting climate control in non‑essential facilities.

Authorities and companies are urging the public to shift air‑conditioner operation to daytime hours, keep thermostat settings between 24 °C and 26 °C, and switch off non‑essential appliances during the peak period. These coordinated steps aim to keep the power system stable without endangering household electricity supply.
