France to run nationwide blackout simulation in 2027

PARIS — Is France ready for a crisis that plunges it into darkness? The French government is planning to find out.

The government is looking to organize a tabletop simulation of a sudden, nationwide power outage in the second half of 2027, according to four people with direct knowledge of the exercise, who were granted anonymity to discuss plans that have not been publicly announced.

The exercise will involve the French electricity grid operators Enedis and RTE as well as several government departments and ministries and the French military administration.

Its purpose will be to determine how the country would respond to a paralyzing electricity outage of the kind that hit Spain and Portugal in April 2025, or a major cyberattack targeting the power grid as Poland experienced last year — an act of sabotage Brussels has attributed to Russian intelligence services.

The simulation will test “the country’s ability to respond,” said one person familiar with preparations for the exercise, adding that it is intended to assess the time needed to restore power and the country’s ability to ensure the continuity of essential services.

The exercise was formally confirmed during an interministerial committee on national resilience on July 8. A detailed announcement should come before the end of the year.

The meeting notes outline other priorities, such as making sure the French state maintains access to goods considered “essential to ensuring the continuity of the state and the protection of the population.”

These include “emergency blankets, generators, medicines, telecommunications equipment, equipment for law enforcement, as well as rare and critical raw materials.”

Stress test

Crisis preparedness has turned into a political issue in France as record-breaking heat and wildfires are forcing the country to reckon with its ability to respond to emergencies.

Last summer, the government updated the country’s National Resilience Strategy, a roadmap on how to “maintain the functions essential to collective life” in the face of war or natural disasters.

Since the start of the summer, many French regions have faced unprecedented temperatures, with mercury levels setting multiple records in June.

In the country’s southwest, out-of-control wildfires fueled by extreme heat and drought forced mass evacuations that affected more than 200,000 people.

In Paris, the mayor made a desperate plea to large-scale food retailers to mobilize ice stocks over fears that first responders would run out of much-needed cubes to cool down victims of heatstroke.

Opposition parties were quick to attack the government over what they described as a widespread lack of preparedness, forcing the executive to defend itself.

French Prime Minister Sébastien Lecornu also announced that the government would submit a bill to parliament to improve emergency response systems.

“We want to refocus fire and rescue services on their core mission and adapt our organization to the crises that lie ahead,” said Lecornu Sunday in an interview with La Tribune Dimanche .
