Overview
SWS Stadtwerke Stralsund GmbH is the municipal utility (Stadtwerke) of the Hanseatic city of Stralsund in Mecklenburg-Vorpommern, Germany. Founded on 27 September 1991, it is a publicly owned company that supplies the city and the surrounding Vorpommern-Rügen district with electricity, natural gas, district heating and drinking water, and it also operates public communications networks and wastewater services. The company describes itself as a regional energy provider for Stralsund, Vorpommern-Rügen and Mecklenburg-Vorpommern, offering private and business customers tariffs for power, gas, heat and water alongside photovoltaic systems, heat pumps and e-mobility solutions. As a kommunales Unternehmen (municipal enterprise), SWS Stadtwerke Stralsund is closely tied to the city and its region. Its website emphasises local engagement, from supporting sports clubs and associations to social projects, and it markets itself on fair prices, personal on-site advice and sustainable energy from renewable sources. Customers can manage meter readings, instalments, contracts and invoices through an online customer portal. The company operates as a holding group with six subsidiaries. These cover the fields of the seaport, water supply, wastewater treatment, electricity supply, communications networks, natural gas supply, heat supply and energy generation. The group's subsidiary structure includes SWS Energie GmbH (51%, with E.DIS holding 49%), SWS Telnet GmbH, SWS Netze GmbH, SWS Natur GmbH, REWA Regionale Wasser- und Abwassergesellschaft Stralsund mbH (71.43%) and SWS Seehafen Stralsund GmbH. According to the company, the group employs around 350 people. SWS Stadtwerke Stralsund positions itself as more than a traditional energy supplier. It invests in green technologies such as combined heat and power plants, photovoltaic systems, heat storage, power-to-heat units, a solar thermal plant under construction and planned wind energy installations integrated into a hydrogen concept. It is also expanding its networks to accommodate electric mobility and heat pump technology, and it pursues digitalisation projects intended to help transform Stralsund into a smart city, including energy forecasting and environmental quality sensors. Its product range includes complete packages such as the StrelaSolar photovoltaic package and a 10 kW heat pump package with hot water preparation, both offered at fixed prices including installation, as well as a 24-month price guarantee for energy tariffs.
