On Tuesday, French news outlet France24 reported that a nation-wide wave of strikes protesting new pension reforms may place the nation’s power and fuel supplies in jeapordy.

The media outlet reported that the nation’s electricity supply had fallen by 3.7 gigawatts, due to sudden power output reductions at two nuclear reactors as well as several thermal power plants. The outlet cited data from power provider EDF. Hydro-plants did not show any reduction in output, however EDF posted a notice of strikes scheduled for Thursday.

French fuel refineries also reported their operations were being impacted by the strikes, as TotalEnergies reported it was seeing interruptions in the shipping of petroleum products. The company was quick to point out however that so far it has seen no shortages recorded at any fueling stations, and that overall levels of supplies at points of sale were still satisfactory.

Reuters reported that it had been told by a spokesperson for the CGT union that it had seen disruptions at the Donges, Normandy, Feyzin, Oudalle, and Flanders refineries, and that according to its information, approximately 75% of the workers at those facilities had gone on strike.

Earlier this month, the government of France presented a new pension reform plan which would see the retirement age for workers raised from the present retirement age of 62, which is the lowest in the EU block, to 64. The plan would also increase the number of years people would have to work to receive a full pension at retirement.

According to polls the plan is immensely unpopular, with over 60% of the population opposing it. French unions have noted the plan is particularly unfair to workers who began working very early in their lives, as well as workers who work physically rigorous jobs, who will now have to continue those jobs longer into their senior years or risk losing their retirement.
