Green Planet Projects GmbH

What Green Planet Projects GmbH does

Green Planet Projects GmbH is a Hamburg-based energy transition service provider and wholly-owned subsidiary of Green Planet Energy eG (formerly Greenpeace Energy eG), Germany's largest eco-energy cooperative. Founded in 1999 (rebranded from Planet Energy to Green Planet Projects in September 2021), the company develops, builds, and operates clean power plants — primarily onshore wind, biodiversity-focused ground-mounted photovoltaics (Freiflächen-PV), biogas-to-biomethane conversion, and PEM electrolysis for green hydrogen. It operates a portfolio of 16 wind farms, 3 PV plants, and 2 electrolysers totaling approximately 130 MW of installed capacity, supplying around 65,000 German households, with cumulative investment exceeding €188M.

The company's core services span the full project lifecycle: project acquisition, greenfield development, financing, construction management, and long-term technical and commercial operations management (typical 30-year tenure). Its specialized offerings include Biodiversity Photovoltaics (solar parks co-designed with flowering strips, skylark windows, native hedges, and 15cm ground-clearance fencing for small animal passage), biomethane conversion for biogas operators seeking to exit EEG subsidy regimes with guaranteed long-term gas offtake, and wind-to-hydrogen electrolysis for surplus electricity monetization. The company maintains a citizen energy (Bürgerenergie) practice, co-founding energy cooperatives and providing community engagement frameworks.

Green Planet Projects generates revenue through three streams: (1) electricity, gas, and hydrogen sales from owned and operated assets, (2) project development and operations management fees for third-party assets, and (3) issuance of Genussrechte (profit participation rights) to retail investors — eight public placements have raised approximately €56.89M from around 7,000 investors since 2004. Its primary customer segments are German municipalities, municipal utilities, citizen energy cooperatives, agricultural landowners, and biogas plant operators. Geographic reach is primarily Germany with a notable Austrian presence (Parndorf). The 21-person team is led by Managing Directors Julian Tiencken and Benjamin Beckert.
