What Helexia Group does

Helexia Group is a France-based energy transition services provider and wholly-owned subsidiary of Voltalia (Euronext Paris-listed renewables operator), specializing in on-site solar photovoltaic generation, battery energy storage, electric mobility infrastructure, and energy performance services for commercial and industrial clients. The company operates a 360° delivery model covering six integrated services: strategic advisory, energy production (rooftop PV, solar carports, agri-PV), energy optimization, asset and energy management, EV charging, and third-party financing. Helexia finances, owns, and operates assets on client sites under 15-20 year Power Purchase Agreements (PPAs) and Energy Performance Contracts (EnPCs), removing upfront CAPEX for clients while generating long-duration recurring revenue for itself.

The company serves large enterprise clients across retail (Auchan, Leroy Merlin, Alcampo, Raia Drogasil), industrial manufacturing (Corticeira Amorim, AGC Flat Glass Iberica), telecommunications (Telefonica/Vivo, TIM Brazil), and energy trading (Comerc Energia, Prime Energy, Vibra Energia). As of December 2025, Helexia operates 520 MW of solar capacity across 1,884 projects in 10 countries (France, Italy, Belgium, Portugal, Spain, Poland, Hungary, Romania, Brazil, Senegal), producing 1,890 GWh annually and avoiding 497 ktCO2. Operating subsidiaries include Helexia France, Helexia Agri (agricultural PV, formerly Cap Sud acquired April 2022), Ewen (energy consulting and monitoring), and Helexia Brazil.

Helexia's business model relies on project-finance debt (€200M+ raised across 2023-2025 tranches from La Banque Postale, Bpifrance, and BNDES) to fund asset deployment. Revenue is generated through electricity sales under PPAs, savings-sharing under EnPCs, EV charging services, and long-term O&M/asset management contracts. In January 2026, Bernard Guntz succeeded co-founder Benjamin Simonis as CEO, signaling tighter operational integration within Voltalia Group.

Revenue model

1. Solar Energy Production & PPA Sales: Helexia develops, constructs, finances and operates photovoltaic power plants on client rooftops and carports. Revenue is generated through Power Purchase Agreements (PPAs) where clients purchase the electricity produced at competitive rates over 15-20 year contract terms. The company retains ownership of assets while providing guaranteed energy supply.
2. Energy Performance Contracts (EnPC): Third-party investment model where Helexia finances complete project realization (EPC) and operation & maintenance. Clients benefit from energy savings without upfront investment, sharing savings with Helexia over the contract length.
3. Electric Mobility Solutions: Installation and operation of EV charging infrastructure (AC and DC charging stations) integrated with solar installations, providing additional revenue streams from charging services and grid services.
4. Asset Management: Long-term operation and maintenance of installed solar assets generating recurring revenue through monitoring, optimization, and performance management services.
