Rheinhessische Energie- und Wasserversorgungs-Gesellschaft mit beschränkter Haftung

Rheinhessische Energie- und Wasserversorgungs-Gesellschaft mit beschränkter Haftung, commonly shortened to "Rheinhessische", is a German municipal utility headquartered in Ingelheim am Rhein in the Rhineland-Palatinate region of Rheinhessen. It traces its origins to the Ingelheim municipal works (Stadtwerke Ingelheim) and has operated as a dedicated energy and water supplier since 1954. The company describes itself as a traditional utility with a future, combining a long local heritage with a modern portfolio of electricity, natural gas, heat and water services. The company supplies households and businesses in and around Ingelheim. Its electricity products are marketed as 100% renewable, sourced from hydropower and verified through guarantees of origin. It also offers natural gas tariffs, heat supply, water in Ingelheim, energy consulting, mobility services, and it is responsible for street lighting in the municipalities it serves. Its product range includes fixed-price tariffs with 12- and 24-month price guarantees, a dynamic electricity tariff, and services such as mini combined heat and power (Mini-BHKW) advice and photovoltaic-related offerings. Ownership is municipal-majority: the city of Ingelheim holds 62.95% of the shares, while Thüga Aktiengesellschaft holds 37.05%. This structure places the Rheinhessische within the broader landscape of German municipal utilities (Stadtwerke) that combine local public ownership with partnership in the Thüga network. The company emphasizes customer satisfaction, regional engagement, and sustainability, positioning itself as a partner for the energy transition and climate protection in Rheinhessen. As a regional supplier, the Rheinhessische operates primarily in the German market, with a focus on Ingelheim and the surrounding Rheinhessen area. Its communications highlight certified customer satisfaction, round-the-clock online services, and a commitment to planting a tree in the Ingelheim city forest for every new electricity customer or tariff switch. The company also maintains a blog covering energy market topics, photovoltaic systems, battery storage and heat pumps, reflecting its role as an advisor on decentralized energy solutions.

The Rheinhessische Energie- und Wasserversorgungs-Gesellschaft mit beschränkter Haftung emerged from the Stadtwerke Ingelheim in 1954. Since then it has operated as a regional energy and water utility based in Ingelheim am Rhein, in the Rheinhessen region of Rhineland-Palatinate, Germany. Over the decades it has expanded its services from basic electricity and water supply to a broader portfolio that includes natural gas, heat, energy consulting, mobility services, and municipal street lighting. A key structural feature of the company is its ownership. The city of Ingelheim holds a 62.95% majority stake, while Thüga Aktiengesellschaft holds 37.05%. This municipal-majority model is typical of German Stadtwerke and allows the company to combine local public accountability with access to the expertise and network of a larger energy holding. The company describes itself as a "traditional company with a future" and emphasizes its role as a neighbor and partner in the region. In recent years the Rheinhessische has aligned its product strategy with the German energy transition (Energiewende). Its electricity tariffs are marketed as 100% renewable, sourced from hydropower and certified through guarantees of origin. It offers fixed-price guarantees of 12 and 24 months, a dynamic electricity tariff, and services related to photovoltaic systems, battery storage, heat pumps, and mini combined heat and power (Mini-BHKW) units. The company also runs a blog addressing energy market developments and practical energy-saving topics for households in Rheinhessen. Customer satisfaction and regional engagement are central to its brand identity. The company states that for every new electricity customer and every switch to an electricity product, it plants a tree in the Ingelheim city forest. It also highlights certified customer satisfaction and round-the-clock online services. Its stated values include friendliness, competence, personal and partnership-based service, and continuous quality improvement. As of the available evidence, the company remains an active municipal utility serving Ingelheim and the surrounding Rheinhessen area. It is not publicly listed; it operates as a GmbH with municipal majority ownership. Its history reflects the broader evolution of German municipal utilities from local infrastructure providers to multi-service energy companies engaged in renewable generation, energy efficiency, and climate protection.
