Renalfa

What Renalfa does

Renalfa Solarpro Group GmbH is a Vienna-based clean energy and e-mobility investment group that operates a vertically integrated platform spanning renewable generation, energy storage, EPC services, energy trading, green hydrogen, and electric mobility across Central and Eastern Europe and the Baltic states. The group holds 779+ MW of operational power-generating assets, with another 1.8+ GW under construction and development, alongside 963 MW / 3,570 MWh of operational and pipeline BESS projects. It also operates 3,000+ EV charging points through Eldrive and a 1,700+ vehicle EV car-sharing fleet through SPARK, with energy trading and aggregation run-rate of 4.5+ TWh per annum via Toki Power.

The company's core technology stack combines utility-scale solar PV, wind, long-duration co-located battery storage (including pioneering lithium-ion + sodium-ion dual-chemistry systems), grid-forming inverters, and an AI-driven dispatch and control platform that converts hybrid assets into dispatchable green baseload products. Engineering, procurement, and construction capability sits in the Solarpro subsidiary, which has delivered 14+ GW of installed PV capacity across 30+ countries with 1,500+ professionals. The group is also developing four green hydrogen plants in Bulgaria with total 400 MWe electrolysis capacity (43 tons/day each) under the Renalfa Hydrogen unit.

Revenue is generated across seven streams: renewable energy generation (utility-scale and corporate PPAs), EPC services (one-time and light EPC), EV charging (transaction fees and subscriptions like Eldrive Smart/Pro), energy trading and aggregation (route-to-market and ancillary services), green hydrogen production (transaction-based), corporate solar-as-a-service and PPAs (multi-year fixed-price contracts), and EV car sharing (per-use fees). Go-to-market combines B2B enterprise field sales for large infrastructure projects and PPAs with industrial consumers (e.g., A1 Bulgaria, Apollo Tyres, Volkswagen, Solvay), direct-to-consumer channels for EV charging and car sharing, and event-driven project acquisition through tenders and industry forums. The group operates two anchor joint ventures with French infrastructure fund manager RGREEN INVEST — Renalfa IPP and Renalfa Power Clusters — alongside the EURA Energy JV with Eurowind Energy, collectively backed by €315M in EBRD-led holdco financing and €200M of RGREEN equity per JV.
