Energiequelle

What Energiequelle does

Energiequelle GmbH, headquartered in Kallinchen (Zossen) near Berlin, is a German independent renewable energy project developer founded in 1997 by Michael Raschemann. The company plans, builds, and operates wind energy parks, photovoltaic installations, battery energy storage systems (BESS), grid connection infrastructure, and substations, and it extends into adjacent energy concepts such as charging infrastructure, Power-to-X, heating and cooling solutions, and agrivoltaic/floating PV. Through its wholly-owned subsidiary eqSTROM GmbH & Co. KG, it sells sustainably produced green electricity to households and businesses, including special local tariffs for residents near its wind farms. Operational management services for third-party wind and solar parks (commercial, technical, electrical) and grid-connected control room operations (Leitwarten) anchored by ISO/IEC 27001 and 27019 certifications provide a recurring service revenue layer.

The business model blends one-off project development revenue (sale or co-development of completed parks to institutional investors such as KGAL and Octopus Energy), recurring operational management contracts, project-specific professional services, and tariff-based electricity supply. Go-to-market is enterprise field sales combined with a community-led model: Energiequelle actively structures citizen and municipality participation (direct investment, EEG municipality payments, Strombonus programs, cooperative ownership) to secure local acceptance — a function embedded directly in its permitting and project-origination workflows. Distribution is handled through dedicated direct sales contacts for municipalities (e.g., Andy Helbig), cooperation partnerships with local entities (Helmetal eG, FEUER powerair GmbH), joint ventures (OQTO-X with Octopus Energy for C&I customers across DACH and Poland/Czech Republic), and a self-service "Check Area Tool" digital channel for landowner origination.

As of late 2025/early 2026, Energiequelle operates with 450+ employees across approximately 20 locations in Germany, France, Finland, Greece, and South Africa. Operational track record includes 850+ installations, more than 1,700 MW of connected wind energy capacity, and roughly 2,000 MW of built grid infrastructure. Active project pipeline spans 17 MW repowering (Minden-Hahlen), 21 MW new wind (Teschendorf commissioned December 2025; Lüben under construction), a 42.5 MW divestiture pipeline to KGAL, a 200 MW BESS partnership with Ingrid, and a €200 million by-2030 C&I investment target via the OQTO-X joint venture.
