GSW Gemeinschaftsstadtwerke GmbH Kamen-Bönen-Bergkamen

GSW Gemeinschaftsstadtwerke GmbH Kamen-Bönen-Bergkamen (commonly shortened to GSW, and presented to customers as Stadtwerke Kamen/Bönen/Bergkamen) is a German municipal utility, or Stadtwerk, serving the three neighbouring towns of Kamen, Bönen and Bergkamen in North Rhine-Westphalia. Its name reflects its structure: a Gemeinschaftsstadtwerk, a joint municipal enterprise shared by the participating municipalities rather than owned by a single town. The company describes itself as a local energy supplier that reliably provides electricity, natural gas, water and heat to its service area while also helping to shape the energy transition at the regional level. GSW's core business is the supply of energy and water to households and businesses. On its consumer-facing side it offers electricity, natural gas, district heating (Fernwärme) and water, together with related services such as the GSW EnergieDach, a leasing model for rooftop solar power that requires no upfront investment from the customer, and a heat-pump leasing model. It also runs online customer and grid-connection portals and a mobile app, "Meine GSW", through which customers can submit meter readings, adjust instalments and check opening hours and pool events. The company states that it employs around 250 people and that its staff are available around the clock to fulfil its public-service mandate. Beyond energy, GSW is a visible civic actor in its region. It operates the GSW Wasserwelt, a group of leisure pools: the Sesekebad in Kamen, a combined indoor and outdoor pool; the Häupenbad in Bergkamen, with a double-racer slide, a large adventure pool and a toddlers' area; and the Saunabad in Bönen, focused on relaxation. The company also sponsors sport, culture and social projects, supports clubs, schools and kindergartens through an annual funding programme, and stages free public events such as the GSW Kamen Kite, GSW Kamen Klassik and the GSW Lichtermarkt. Its managing director is Alexander Loipfinger. As a municipal utility, GSW positions itself around Daseinsvorsorge — the German concept of services of general public interest — and around local rootedness. Its stated aim is to combine sustainable and economically sound supply solutions to secure a climate-safe future for the region, and to create value for Kamen, Bergkamen and Bönen. The company is active in the local energy transition, including cooperation on green electricity from a local biogas plant for its "GSW Strom Natur Plus" product and participation in energy-sharing arrangements. It communicates with customers through its website, customer centres, app and telephone service, and issues warnings about fraudulent calls targeting customer data.

GSW Gemeinschaftsstadtwerke GmbH Kamen-Bönen-Bergkamen is a joint municipal utility, or Gemeinschaftsstadtwerk, formed to serve the three adjacent North Rhine-Westphalian towns of Kamen, Bönen and Bergkamen. Its corporate name records this shared structure directly: rather than belonging to a single municipality, it is a common enterprise of the participating towns, which is the meaning of the German term Gemeinschaftsstadtwerk. The company presents itself to customers under the descriptive name Stadtwerke Kamen/Bönen/Bergkamen. As a Stadtwerk, GSW's historical role is bound up with the German tradition of municipal Daseinsvorsorge — the provision of essential services of general interest at the local level. Over time the company has built a portfolio spanning electricity, natural gas, water and heat (including district heating), supplied to households and businesses across its three-town service area. Its stated mission combines reliable supply with active participation in the energy transition, aiming at what it describes as a secure climate future for the region through sustainable and economically sound solutions. In recent years GSW has extended its offering beyond conventional supply. It has introduced products and service models aimed at decentralised and customer-owned energy, including the GSW EnergieDach, a leasing model that lets customers use rooftop solar power without an upfront investment, and a heat-pump leasing model in which the company handles installation, service and support in return for a monthly lease payment. It has also developed digital customer channels, notably the "Meine GSW" app for meter readings, instalment changes and information about customer centres and pool events, alongside online customer and grid-connection portals. In 2026 the company highlighted cooperation with the farmer Wortmann to source green electricity from a local biogas plant for its "GSW Strom Natur Plus" tariff, and noted the introduction of energy sharing in its market from 1 June 2026. GSW's history is also civic and recreational. Through its GSW Wasserwelt it operates three leisure pools: the Sesekebad in Kamen, combining indoor and outdoor facilities; the Häupenbad in Bergkamen, featuring a double-racer slide, a large adventure pool and a toddlers' area; and the Saunabad in Bönen, dedicated to relaxation. The company sponsors sport, culture and social projects, runs an annual funding programme for clubs, schools and kindergartens, and organises free public events including the GSW Kamen Kite, GSW Kamen Klassik and the GSW Lichtermarkt. It states that it employs around 250 people and that its staff work around the clock, seven days a week, to meet its public-service obligations. Alexander Loipfinger serves as managing director. The company communicates with its customers through customer centres, telephone service, its website and its app, and has publicly warned about fraudulent calls attempting to obtain sensitive customer data.
