What Berliner Stadtwerke does
Berliner Stadtwerke is a municipal energy company headquartered in Berlin, founded in 2014 and wholly owned by the City of Berlin. It operates through three private limited companies — Berliner Stadtwerke GmbH (parent), Berliner Stadtwerke EnergiePartner GmbH (retail), and Berliner Stadtwerke KommunalPartner GmbH (municipal partnerships) — under a unified brand. Since inception it has invested €172 million into renewable generation assets including rooftop and ground-mounted solar, wind parks (Albertshof, Teltow II), and block-type combined heat and power plants, producing 122,563 MWh of eco-electricity in 2025 and avoiding 219,600 tonnes of CO₂.
The company supplies TÜV-certified 100% renewable electricity to residential and commercial customers across Berlin and Brandenburg via a portfolio of tariff products: berlinStrom and brandenburgStrom for households, berlinStrom Gewerbe and brandenburgStrom Gewerbe for SMEs up to 80,000 kWh, wärmeStrom for heat pumps, and the Mieterstrom tariffs berlinStrom Sonne+ (rooftop solar) and berlinStrom Wärme+ (CHP) for tenants in buildings where Berliner Stadtwerke has installed generation. It also operates public EV charging infrastructure across Berlin and offers district energy concepts (Quartierskonzepte), heat project development, funding advisory, and climate protection strategy services. Customers include 600+ Berlin schools, BIO COMPANY (63 stores), Vivantes healthcare, HOWOGE housing, and BVG transit.
Revenue is generated almost entirely through recurring, consumption-based electricity supply contracts billed monthly. Go-to-market combines a direct-to-consumer online tariff calculator with inside sales (toll-free 0800 line), a joint physical customer center with Berliner Wasserbetriebe, B2B enterprise sales for customers above 80,000 kWh, and a referral program offering up to €100 bonuses. Distribution leverages partnerships with housing companies and public institutions for bulk supply. As a kommunalversorgungsunternehmen, profits are reinvested in Berlin's energy transition rather than distributed to shareholders, and there is no private equity, venture, or external investor ownership.
