France has recorded 520 hours of negative electricity pricing from the beginning of 2026 until September 27, according to data compiled by Bloomberg. This is equivalent to nearly 22 days combined and exceeds the total for the entire year of 2025, which had previously recorded 513 hours of negative pricing. RTE, the French electricity transmission system operator, noted that the number of negative pricing hours has increased significantly over the past three years, from 147 in 2023 to 352 in 2024. In comparison, Germany recorded 463 hours of negative pricing as of September 27, while Spain recorded 703 hours, an increase of 31% year-on-year. Negative electricity prices occur when supply exceeds demand on the wholesale market, often due to high renewable energy production from solar and wind sources when consumption is low. In such cases, electricity sellers may accept prices below zero to offload their production. However, this does not always mean producers stop operations, as shutting down and restarting facilities can incur costs, and some support mechanisms may encourage continued production. France's record of negative pricing hours indicates that the country produces more electricity than it can consume, store, or export. The phenomenon began early in 2026, with significant increases in April, influenced by the progress of solar production and the availability of the nuclear fleet. RTE suggests that the multiplication of negative prices is also linked to delayed electrification of uses and slow recovery in electricity consumption. Laurent Néry, director of market analysis at Engie, noted in May 2025 that negative prices are not a surprise and that solutions exist to address them, highlighting the need for better alignment of consumption with periods of high production. These solutions include shifting consumption to times of high production, such as charging electric vehicles or running water heaters during the day, and investing in battery or pumped storage stations. While negative prices can reduce the average price of electricity on the wholesale market, thereby potentially lowering suppliers' procurement costs and exerting downward pressure on consumer prices in the long term, they have not led to a decrease in electricity bills this year. As of August 1, the regulated electricity price increased by an average of 2.5%, despite the record number of negative price hours. The increase is attributed to higher network costs and the need to ensure sufficient electricity during periods of high consumption. The Ministry of Energy stated that the increase also allows for investment in maintaining production capacity for the winter season and maintaining public electricity networks, particularly important during extreme heat episodes.
