What ZE Energy does

ZE Energy is an independent French renewable energy producer specializing in battery energy storage systems (BESS) and hybrid solar-plus-storage projects. Founded around 2020 by Mathieu Lassagne and headquartered in Paris (5 rue de la Terrasse, 75017), the company develops, finances, builds, and operates energy assets across France, Italy, and Germany. Its current operating portfolio comprises roughly 284 MW / 1.2 GWh of battery storage and 113 MW of solar PV, with a stated pipeline target of 1.5 GW by 2029.

The company's core technology centers on two configurations: standalone BESS, which provides grid flexibility services such as balancing, frequency regulation, and congestion relief for transmission and distribution system operators; and hybrid solar-plus-BESS systems, which co-locate photovoltaic generation with storage to deliver dispatchable green power. Notable operational assets include France's first standalone solar-plus-storage project at Saint-Sauveur (2020), the 18 MW PV / 7.5 MW–7.5 MWh Gièvres project (2022), and the 77 MW PV / 14.8 MW–35 MWh Project Vert in Landes (2025). Flagship pipeline includes the 98.5 MW / 832 MWh Sessa Aurunca standalone battery project in Campania, Italy, developed jointly with Octopus Energy Generation under a 15-year fixed tender contract with 2028 commissioning target.

ZE Energy monetizes assets through three primary channels: competitive public tenders (MACSE in Italy, CRE and RTE in France), Corporate PPAs with large energy consumers (Orange France signed May 2024; Sorégies since 2021), and project development fees and carried interest from co-investment partnerships. The company has raised over €98 million across three funding rounds from institutional investors including Marguerite, Amundi Energy Transition, Demeter, Sorégies, HTGF, and Acofi Gestion. Its headcount of 11–50 is lean relative to the capital intensity of its assets, reflecting an outsourced-construction developer-operator model with localized country management for each market.

Products and services

• Standalone Battery Energy Storage System (BESS) Autonomous battery energy storage systems that store excess electricity and deliver power on demand, enabling grid stabilization, volatility management, and congestion relief without being paired with renewable generation. Targeted at transmission and distribution system operators.
• Hybrid Solar+BESS Combined photovoltaic solar generation with integrated battery storage enabling continuous, dispatchable power delivery and optimized energy valorization. Targeted at large corporate energy consumers via Corporate PPAs.
• Grid Flexibility Solutions Storage-based services that provide flexibility to electricity grids including balancing supply and demand, stabilizing grid frequency, and relieving transmission congestion. Sold to grid operators via competitive tenders and long-term contracts.
• Energy Asset Optimization Services to optimize energy asset performance through storage and flexibility, managing market volatility and maximizing energy value over the asset lifecycle.
• Project Development Services End-to-end project development covering conception, financing, construction, and operation of battery storage and solar PV projects, executed for own portfolio or with co-investment partners across France, Italy, and Germany.
