France Considers Free Electricity Periods to Optimize Solar Energy Use

Inspired by Australia's 2026 initiative offering free electricity during midday peak solar production, France is exploring a similar approach to better utilize its abundant solar output. In 2025, France lost about 1.6 TWh of solar energy due to negative electricity pricing, which occurred during 513 hours—an increase from 352 hours in 2024. These negative prices, often between 11 AM and 5 PM when solar production is highest, prompt some producers to reduce or stop generating electricity to avoid losses.

Australia's Solar Sharer Offer leverages smart meters to provide consumers with several hours of free electricity daily, encouraging usage of appliances and EV charging when solar supply peaks. France is considering implementing 'solar hours' where electricity could be free or low-cost for two to three hours during high renewable output times. With smart meter infrastructure, this would incentivize flexible consumption, improving alignment between supply and demand and reducing wasted potential.

According to reports from RTE and the French energy regulator CRE, the country also experienced 1,807 hours with electricity prices exceeding 100 €/MWh in 2025, underscoring the imbalance between production and consumption timings. The proposed strategy aims to make renewable energy more accessible and advantageous for consumers, potentially improving public perception of solar benefits and addressing shortcomings of the current pricing system.

As solar energy becomes increasingly dominant in the grid, this innovative demand-side management could lead to a more efficient and sustainable energy landscape in France.
