What Corsica Sole does
Corsica Sole SAS is a French independent power producer (IPP) founded in 2009 in Corsica by Paul Antoniotti and Michael Coudyser, operating across the full project lifecycle — land acquisition, permitting, financing, construction, and long-term asset management — of solar photovoltaic, battery energy storage, and green hydrogen assets. As of FY2025 the company operates 150 MWc of solar generation and 360 MWh of battery energy storage systems (BESS), supported by a development pipeline of 1 GW of solar and 5 GWh of storage (with nearly 3 GWh targeted for deployment by 2028). It maintains offices in 12 locations across metropolitan France, French overseas territories, and Italy, and reports operational presence in six European countries.
Its technology stack spans ground-mounted and agrivoltaic solar, large-format stationary batteries (with Tesla-supplied systems for installations including Giurone), and an in-house Energy Management System (EMS) described as providing real-time monitoring and optimization of energy production and distribution. Battery assets are dispatched into ancillary services including frequency containment reserve, restoration reserves, and capacity auctions, while solar is monetized primarily through long-term Power Purchase Agreements (PPAs).
The revenue model is asset-backed and recurring in nature: electricity sales under PPAs and grid-operator offtake generate the largest revenue stream, ancillary services and aggregation contracts (Agregio Solutions in France) monetize storage flexibility, project development and asset management fees supplement income, and an emerging hydrogen line at the Folelli facility targets island-territory energy autonomy. Customers split across grid operators (RTE, Baltic grid operators), institutional investors (Banque des Territoires, Mirova, EBRD), industrial and commercial offtakers (e.g., a 10-year FPPA with Pure Energy in Estonia), agricultural cooperatives (agrivoltaics), and local authorities. FY2025 revenue was €37.5M on a headcount of 200 collaborators, with capital sourced from a combination of founder ownership, joint investment platforms (notably the €150M Corsica Sole Hexagone platform with Banque des Territoires), and structured project finance from lenders including Bpifrance, Crédit Coopératif, EBRD, and Nordic Investment Bank.

Products and services
- Solar Energy and Agrivoltaics Development, construction, and operation of photovoltaic solar power plants including agrivoltaic systems that combine agricultural production with solar generation on the same land, plus rooftop and carport installations. Targeted at grid operators, municipalities, agricultural cooperatives, and industrial customers.
- Energy Storage (Battery Energy Storage Systems) Large-scale stationary battery energy storage systems (BESS) providing grid balancing, flexibility, frequency regulation, capacity, and security services. Includes standalone storage installations and hybrid solar-plus-storage projects. Targeted at grid operators and utilities (e.g., RTE, Baltic Grid Operators).
- Green Hydrogen Production Green hydrogen production facilities developed along the full value chain from feasibility studies through project structuring to deployment, supporting energy autonomy for island territories (e.g., Folelli facility in Haute-Corse).
- PPA – Power Purchase Agreement (Electricity Sales) Long-term electricity sales through power purchase agreements, enabling corporate and institutional buyers to source renewable energy directly from Corsica Sole's generation assets under contracted terms.
- Collective Self-Consumption Solutions enabling multiple consumers (communities, businesses) to share locally produced renewable energy, optimizing self-consumption and reducing grid dependency.
- Beuvry Battery Storage Facility A standalone 50 MW/100 MWh battery energy storage facility in Beuvry, Hauts-de-France — Corsica Sole's first mainland France stationary storage asset, providing grid services and financed by Bpifrance and Crédit Coopératif.
- Hertz 1 Battery Storage Facility A 100 MW/200 MWh battery energy storage facility in Kiisa, Estonia, designed to stabilize the regional power system following the Baltics' synchronization with the European continental grid.
