French energy unions' 24‑hour strike cuts electricity supply and Dunkirk gas terminal output

Industrial action by French energy‑sector unions is set to curtail electricity generation by as much as 5 gigawatts on Tuesday, as workers observe a 24‑hour strike. The walkout is being staged in response to proposals that would limit employee benefits, including the privilege of accessing electricity at reduced rates.

The strike, organized by several unions representing staff at power plants and grid operators, is expected to affect the national supply balance and may prompt grid managers to rely on reserve capacity or import additional power to meet demand. Authorities have warned that the reduction could strain the system if demand peaks, but have also indicated contingency plans are in place to mitigate disruptions. The action underscores ongoing tensions between labor groups and government officials over cost‑saving measures in the energy sector.
