Kallista Energy

What Kallista Energy does

Kallista Energy is a Paris-headquartered independent renewable energy producer founded in 2005 that develops, finances, builds, and operates wind, solar, battery storage, and ultra-fast EV charging infrastructure across France, Germany, and the Netherlands. As of 2025, the group owns and operates 43 generation and charging sites totaling 434 MW of installed capacity, supplying approximately 654,000 MWh of renewable electricity annually to roughly 288,000 inhabitants. Its technical stack spans onshore wind turbines (including Enercon E-115 units at Windpark Krammer), solar PV, Lithium Iron Phosphate (LFP) battery storage (a 120 MW / 240 MWh project at Saleux under construction in 2025-2026 with Envision Energy and AESC cells), and the YAWAY network of ultra-fast EV charging stations capable of up to 400 kW per vehicle, several of which are directly connected to Kallista-owned wind or solar farms for short-circuit renewable supply.

The company generates revenue through three principal streams: (i) sale of renewable electricity to the grid and to corporate off-takers under power purchase agreements (PPAs), with named counterparties including Lhyfe and Groupement Les Mousquetaires; (ii) grid services, notably frequency regulation provided to French TSO RTE via BESS on reserve markets; and (iii) transaction-fee revenue from the YAWAY consumer EV charging network at approximately €0.30/kWh. Kallista was a pioneer of wind repowering in France beginning in 2017 and has 7 parks repowered or in progress, with more than 200 MW of repowering projects authorized. The company is privately held by institutional investors APG Asset Management (majority) and Ardian, with employee ownership via a long-term savings plan since 2020.

Kallista pursues a vertically integrated, project-development-led go-to-market, engaging directly with landowners, farmers, local authorities, and municipalities for land agreements and permitting, while simultaneously serving end consumers through YAWAY and corporate buyers via PPAs. The company has earned seven consecutive GRESB 5-star sustainability ratings and was ranked 2nd in the Wind Power Generation category (2025), validated SBTi climate targets, and a French Gender Equality Index of 92/100 for 2025-2026. Headcount stands at approximately 110 employees across offices in Paris, Bordeaux, Lyon, Hamburg, and Rotterdam.

Revenue model

1. Renewable Electricity Generation and Sales: Kallista Energy owns and operates wind farms, solar parks, and charging stations. Revenue is generated through the sale of electricity produced from renewable sources to the grid or directly to end consumers via power purchase agreements (PPAs). The company also provides grid services such as frequency regulation through battery storage systems.
2. Battery Energy Storage Services: Battery storage systems provide frequency regulation services to grid operator RTE on reserve markets, generating revenue through system services while supporting renewable energy integration.
3. EV Charging Services (YAWAY): Ultra-fast charging stations for electric vehicles offering rates around 0.30 €/kWh, directly connected to renewable energy sources. Stations can host 8-48 charging points and are designed for high throughput along major road corridors.
