The Aporia
On September 14, 2026, a labour strike by power sector unions in France took 6.5 gigawatts of electricity offline overnight, according to data from EDF. The disruption came primarily from reductions at seven French nuclear reactors and several hundred megawatts of gas-fired and hydroelectric power plants being shut down. Given that France generates about 70% of its electricity from its fleet of 57 nuclear reactors, this strike significantly impacted both domestic supply and export capabilities to neighboring countries like Germany, which relies heavily on natural gas and faces higher energy costs.
The French Court of Auditors had previously estimated that offering discounted rates for gas and electricity to workers and retirees in the energy sector cost EDF over €700 million ($808.22 million) in lost revenue in 2024, leading to a recommendation to end this benefit. The unions are protesting against these recommendations, with the strike expected to continue through Tuesday, September 15, 2026, potentially extending or worsening the power outages.
The majority of the electricity supply cut came from reductions at seven French nuclear reactors, with several hundred megawatts of gas-fired and hydroelectric power also offline.
Workers and retirees in the French energy sector pay discounted rates for gas and electricity, which their unions view as a core part of their compensation package.
