Energy Southern Bavaria

What Energy Southern Bavaria does

Energie Südbayern GmbH (ESB) is a regional energy utility headquartered in Munich, founded in 1966 and operating across Oberbayern and Niederbayern in Southern Bavaria, Germany. The company supplies residential and business customers with natural gas (including BIO gas), certified green electricity, district heating and heat-related services, and e-mobility products such as charging tariffs, charging cards, e-carsharing, and THG quota handling. Through its subsidiaries Energienetze Bayern, ESB Wärme, and ESB Erneuerbare Energien, ESB owns and operates regional gas distribution networks, district heating infrastructure, and renewable generation assets including solar parks and hydropower. The company is 100% publicly owned by Stadtwerke München and Thüga Aktiengesellschaft.

ESB serves roughly 160,000+ households and 15,000 business customers across Southern Bavaria, alongside municipal clients for whom it provides water management, communal heating planning, broadband infrastructure, and renewable energy project development. Its go-to-market combines direct-to-consumer channels (an online customer portal at onlineservice.esb.de, regional KundenCenter locations such as the new Ebersberg site, and a free hotline) with direct municipal partnerships bundled through the Plattform Energie coalition. Revenue is generated through recurring monthly subscription-style tariffs (fixed-price green electricity and gas, dynamic electricity, heat electricity, and EV charging tariffs), municipal managed services, and—newly—a hydrogen delivery product, H2Direkt, which was the first hydrogen delivery contract for private end customers in Germany. The company operates around 2,000 own EV charging points and offers roaming access to 100,000+ charging points across Europe, supported by sub-brands including SONNENstrom (regional solar), TreuePlus (loyalty discounts), and the recently launched IsarFlitzer e-carsharing service.
