Regionalwerk Bodensee

Regionalwerk Bodensee is an independent regional energy utility based in Tettnang, in the Bodensee (Lake Constance) area of Baden-Württemberg, Germany. It was founded in 2008 by seven municipalities — Eriskirch, Kressbronn, Langenargen, Meckenbeuren, Neukirch, Oberteuringen and Tettnang — which together hold a 52% majority stake. The remaining shares are held equally at 24% each by Stadtwerk am See GmbH & Co. KG and Alb-Elektrizitätswerk Geislingen-Steige eG. The company supplies electricity and natural gas to roughly 60,000 people in its service area, and also operates the local distribution network. The utility positions itself as a local, customer-oriented energy provider. Its product range includes electricity tariffs (including green electricity and heat-pump electricity), natural gas, district heating (Nahwärme), solar energy solutions, and public electric-vehicle charging under the Regionalwerk MobilStrom brand. It markets price guarantees on some tariffs, such as a guarantee through the end of 2028 on its main electricity product, and offers referral bonuses to customers. The company also provides services such as billing, customer portal, relocation service and contract management. Regionalwerk Bodensee is expanding into renewable heat. In partnership with Engie Deutschland within the Wärmeversorgungsgesellschaft Tettnang mbH, it is building a district heating network in Tettnang, with construction starting in 2025. The network is initially planned to connect 14 municipal and state-owned buildings, with potential extension to surrounding residential, commercial and industrial areas. The project is expected to save up to 4,176 tonnes of CO2 annually compared with the previous gas boilers, and is partly financed by the European Union's NextGenerationEU programme. The company remains a privately held regional utility, owned by its founding municipalities and two regional energy partners. It continues to invest in modern energy solutions, including solar and EV charging infrastructure, to support the energy transition in the Bodensee region.

Regionalwerk Bodensee was founded in 2008 by seven municipalities in the Bodensee region of Baden-Württemberg: Eriskirch, Kressbronn, Langenargen, Meckenbeuren, Neukirch, Oberteuringen and Tettnang. The company was established as an independent regional energy utility, with the municipalities holding a combined 52% majority. The remaining 48% was split equally between Stadtwerk am See GmbH & Co. KG and Alb-Elektrizitätswerk Geislingen-Steige eG, each holding 24%. This ownership structure was designed to keep the utility locally anchored while benefiting from the expertise of established regional energy partners. Since its founding, Regionalwerk Bodensee has supplied electricity and natural gas to private and business customers in its service area, covering around 60,000 people. It also operates the local distribution network. Over time, the company expanded its offering beyond basic supply to include green electricity products, heat-pump electricity tariffs, solar energy solutions and public electric-vehicle charging under the MobilStrom brand. In the 2020s, the company increasingly focused on the energy transition. It introduced tariffs with long-term price guarantees, such as the Strom 2028 tariff with a price guarantee through the end of 2028, and Ökowärmestrom tariffs with a guarantee through the end of 2027. It also launched referral bonus programmes for customers. A major recent development is the district heating project in Tettnang. Construction of the Nahwärme network began in 2025. The project is carried out through the Wärmeversorgungsgesellschaft Tettnang mbH, a partnership between Regionalwerk Bodensee and Engie Deutschland. Under this arrangement, Engie Deutschland organises the construction of the heating network, while Regionalwerk Bodensee operates the network and handles sales. The network is initially planned to connect 14 municipal and state-owned buildings, with the possibility of extending to adjacent residential, commercial and industrial areas in the coming years. The project is expected to save up to 4,176 tonnes of CO2 annually compared with the previous gas boilers and is partly financed by the European Union's NextGenerationEU programme. Regionalwerk Bodensee continues to operate as a privately held regional utility, owned by its founding municipalities and two regional energy partners, and remains active in supplying electricity, gas and heat while investing in renewable energy and e-mobility infrastructure.
