What Stadtwerke Unna does

Stadtwerke Unna GmbH is a municipally owned multi-utility (Stadtwerke) headquartered in Unna, North Rhine-Westphalia, Germany, serving residential (Privatkunden) and business (Geschäftskunden) customers across the Unna service area. The company is wholly owned by the Stadt Unna (Municipality of Unna) and is governed by a Supervisory Board chaired by Klaus Tibbe, with Jürgen Schäpermeier serving as Managing Director (Geschäftsführer). The firm is regulated by Regulierungskammer Nordrhein-Westfalen and has published annual Umwelterklärungen since 2004, with current TÜV, EMAS, TSM (DVGW/VfD), BREKO, and RenewablePLUS certifications.

The core product portfolio spans regulated energy and infrastructure services: Strom (electricity), Erdgas (natural gas), Trinkwasser (drinking water), and Fernwärme (district heating) supplied through Unna-Süd. Adjacent product lines include the glaspower FTTH internet service (150–1000 Mbit/s, symmetric and asymmetric, 12/24-month contracts), the EnergieDach photovoltaic line with purchase or Pacht (leasing) options plus optional battery storage, and E-Mobilität services covering e-car leasing and a public charging tariff (MobilWatt). The company operates its own local distribution grid through the SWU-Netz GmbH subsidiary, which separates regulated network operations from retail supply, and supports an energy cooperative partnership with Unna Pflanzt Energie eG.

The business model is subscription-based utility revenue, supplemented by regulated network fees (SWU-Netz), hardware sales and leasing (PV, e-car), and ancillary services such as independent Energieberatung including individualized Sanierungsfahrpläne (iSFP) and the Vorteilswelt customer loyalty program with Förderprogramme, the EnergieSparbuch, the customer card, and the Meine Stadtwerke Unna mobile app. Go-to-market is direct-to-consumer and direct-to-SMB via a multi-channel mix: the sw-unna.de website with online tariff and configuration tools, the Kundenportal, physical customer service at the Heinrich-Hertz-Straße headquarters, and phone-based support for both sales and Störmeldung (fault reporting). With 51–100 employees and a single-municipality footprint, the company operates as a vertically integrated local utility and is currently managing a system disruption affecting its online Kundenportal and app services.

Broad incumbents

• E.ON: Large German energy incumbent operating electricity distribution, retail energy, and network services nationally. Competes with Stadtwerke Unna in retail supply and sets the regulatory and competitive context in which municipal utilities operate.
• Deutsche Telekom: Germany's largest telecommunications incumbent with nationwide FTTH and VDSL rollouts, including in Unna. Competes head-on with the glaspower fiber and fixed-line offering.

Emerging players

• Lichtblick SE: German green electricity and e-mobility provider competing for residential energy customers in NRW. Comparable in focus on renewable retail supply, decentralized energy, and EV-related services, though operating without a local network.
• Deutsche Glasfaser: Specialist FTTH provider actively building fiber networks in NRW rural and suburban markets, including the Unna region. Direct competitor to the glaspower product line in fiber-to-the-home rollouts.

Direct peers

• Stadtwerke Dortmund: Larger NRW municipal utility with the same multi-utility stack (electricity, gas, water, heat, fiber) and municipal ownership structure. Comparable product portfolio and go-to-market approach at a larger city scale.
• Stadtwerke Lünen: Neighboring NRW municipal utility serving a city adjacent to Unna. Operates electricity, gas, water, heat, and broadband services under a comparable municipal-utility charter and customer scale.
• Stadtwerke München: One of Germany's largest municipal utilities, operating electricity, gas, district heating, water, and telecommunications (M-net) under the same integrated Stadtwerke model. Same business architecture at much larger scale.
• Stadtwerke Bonn: NRW municipal utility offering electricity, gas, water, district heating, and telecommunications. Operates under an almost identical municipal-utility model with comparable regulatory oversight by the NRW regulator.
• Stadtwerke Hamm: Neighboring NRW municipal utility offering the same multi-utility portfolio (electricity, gas, water, heat, fiber internet) to a similarly sized city. Highly comparable business model, ownership structure, and regulatory environment to Stadtwerke Unna.

Others

• Westnetz GmbH: Network operator subsidiary of Westenergie/E.ON that operates electricity and gas distribution networks in NRW and beyond. Comparable in operating electricity and gas network infrastructure, but at a vastly larger regional scale.
