Gasag Gruppe

What Gasag Gruppe does

Gasag Gruppe is a Berlin-based, privately-held integrated energy company founded in 1847 that supplies electricity and natural gas to more than 700,000 private and business customers across Berlin and Brandenburg. The group operates a vertically-integrated model spanning energy procurement, regulated network operations through its NBB subsidiary (approximately 14,000 km of gas networks), retail supply of electricity and gas (including Ökostrom and Ökogas with RenewablePLUS certification), energy services and contracting, EV charging infrastructure, and increasingly its own renewable generation (28 MW Mallnow wind farm operational summer 2025, with approximately 100 MW of PV projects in development targeting a ~300 MW renewable portfolio). The company is undergoing a strategic transition toward climate neutrality by 2040, with capital deployment into geothermal heating, photovoltaic installations, hydrogen-ready gas infrastructure (over 50 km approved for Germany's national hydrogen core network), and innovative waste heat recovery projects such as the DATA2HEAT joint venture with Investa Real Estate and the Pallasseum district heating project with Deutsche Telekom.

Revenue is generated through a combination of regulated network charges (NBB), recurring retail electricity and gas subscriptions (GASAG|STROM, GASAG|ERDGAS, Ökostrom, Ökogas, Eisbären-branded tariffs), dynamic time-of-use tariffs (GASAG|Flex) integrated with the cloud-based Home Energy Management System platform, and managed services/contracting for urban neighborhood energy systems (Quartierslösungen) and ESCO-style projects. The go-to-market combines direct-to-consumer digital self-service (MEINE GASAG portal, mobile app, WhatsApp customer service) for price-sensitive residential and SMB segments, and enterprise field sales for complex decarbonization projects targeting large property owners, municipalities, and real estate developers such as Gewobag and Investa. Approximately 1,700 employees serve the Berlin-Brandenburg market, with the company operating several subsidiaries including NBB Netzgesellschaft Berlin-Brandenburg, GASAG Solution Plus (innovative energy solutions), EMB Energie Brandenburg, and a regional Energie Brandenburg sub-brand targeting affordability-conscious Brandenburg customers.
