Early Saturday morning, approximately 160,000 households in Cannes and nearby regions lost electricity, as officials confirmed arson at an electricity substation in Tanneron. The situation escalated when an electricity pylon near Villeneuve-Loubet was intentionally damaged, leading to a second outage. Despite the challenges, festival organizers announced they would proceed with the closing ceremony, relying on alternative power sources.

Restaurants and businesses across Cannes struggled to cope with the power loss. “Another hour and I’ll throw everything away,” lamented Laurent Aboukrat, owner of Jamin restaurant, as his fridges remained non-operational. Australian producer Darren Vukasinovic described the atmosphere, stating, "Cannes is in a total slowdown, meltdown; there's no coffee, and I think the town has run out of croissants."

The power cuts interrupted several screenings before the festival team was able to activate backup generators. As the day unfolds, attention is steadily turning towards the evening's climax, where the esteemed Palme d'Or winner will be announced, led by French actress Juliette Binoche and her jury.
