Storage boom in France: record pipeline for 2025–2026
After a dynamic first half of 2025, Storio Energy — a pioneer in B2B energy storage — shares an update on the accelerating energy transition among electro-intensive industries. This trend is driven by volatile energy markets and the continued drop in battery prices. As of today, Storio Energy has identified over 600 MWh in battery storage projects by 2026, spread across around fifty projects, representing an estimated investment of €120 million. This alone equals half of the currently deployed battery storage capacity in France.
Storio Energy: The All-in-One Smart Battery Solution for Industry
Their technology combines electricity storage with an AI-driven platform that charges batteries when prices are low (spot market) and discharges them during price peaks. This system can cut electricity bills by up to 20% while also generating income by stabilizing the grid. The return on investment ranges from 2 to 4 years for most projects, with a lifespan of 15 years.
Storio Energy offers two distinct solutions: one using autonomous containerized batteries charged during low-price periods, and another coupled with photovoltaic installations — such as the project with Baudin Chateauneuf — where the battery optimizes solar self-consumption. In both cases, Storio Energy maximizes energy savings through AI, while providing a buffer against increasing electricity market volatility.
S1 2025: Marked by Price Volatility
In its updated June edition of the French spot electricity price observatory, Storio Energy highlights the system’s vulnerability to weather fluctuations. For instance, while the average low price stood at €22/MWh during the first two weeks of June, a heatwave caused electricity demand to surge by 10% in the second half of the month — pushing the average price up to €59/MWh. Gas-fired power plants were called upon to meet the spike in demand, representing up to 6% of France’s electricity mix, particularly in the evenings.
Between January and June 2025, the average daily spread between the lowest and highest prices reached €98/MWh — a 54% increase compared to the first half of 2024. This record level now consistently exceeds the Levelized Cost of Storage (LCOS), estimated at €60–80/MWh.
Jean-Yves Stephan, CEO & Co-Founder of Storio Energy: “Heatwaves, price volatility, grid stress — all point to the same conclusion: dynamic electricity management is becoming essential. In this context, flexibility solutions are a must. Our batteries adapt their charge cycles to absorb excess production — often in the afternoon when prices turn negative — and release electricity in the evening. This creates a dual benefit: economic and environmental. We’re proud to help our clients boost both competitiveness and resilience through our turnkey storage solutions.”
