Stadtwerke Altena

What Stadtwerke Altena does

Stadtwerke Altena GmbH is a municipal utility (Stadtwerke) founded in 1858 and headquartered at Linscheidstr. 52, Altena, in the Sauerland region of North Rhine-Westphalia, Germany. The company supplies natural gas and drinking water to approximately 5,000 households and businesses in the Altena network area and to the neighboring municipality of Neuenrade under a long-term wholesale water contract. It is the designated basic supplier (Grundversorger) for the Altena service area under German energy law, and it owns and operates 134 km of water mains (drawing from the Fuelbecke Talsperre dam, Springer Quelle spring, and Wasserwerk am Stortel) and 92 km of gas pipelines, the latter operated under DVGW standards with the network leased to Enervie Vernetzt GmbH since 2011.

The product portfolio centers on three core lines: natural gas under the BURGgas sub-brand (including the BURGgas fix tariff with price guarantee through end-2026), drinking water supply at an annual volume of 0.89 million cubic meters, and network operations (Netzbetrieb) for water and gas. Adjacent lines include heating services (gas heating, heat pumps), photovoltaic advisory, e-mobility charging, wastewater management, and two public bathing facilities (Dahler Bad and Freibad Linschweid). Distribution runs through a regional customer center (Kundencenter am Markaner), an online customer portal, a free service hotline (0800 9184-001), and on-site field-services; pricing is published, monthly-billed, and subject to German energy-law oversight.

The business model is subscription-recurring utility revenue from regulated and quasi-regulated residential and B2B water and gas tariffs. The company is privately held as a GmbH, with 75.1% ownership held by the city of Altena (Stadt Altena) and 24.9% by Mark-E AG (Hagen) since 1995. FY2024 disclosed revenue was €17.3M against a €37.3M balance sheet, with approximately 30 employees serving ~17,000 inhabitants — implying high revenue-per-employee for a utility, consistent with outsourced network operations and a small overhead base. Profits flow substantially to the municipal shareholder via taxes and concession fees, reinforcing the local-utility mandate over growth at scale.

Direct peers

• Stadtwerke Plettenberg: Small Sauerland municipal utility serving Plettenberg with comparable utility services. Very similar in footprint, scale, and business model, making it one of the closest natural comparables in the region.
• Stadtwerke Neuenrade: Neighboring municipal utility in Neuenrade and existing 50-year water partnership counterparty. Comparable in size and Sauerland focus, and represents both a peer and a key customer relationship for Stadtwerke Altena.
• Stadtwerke Iserlohn: Municipal utility serving the nearby Sauerland city of Iserlohn with gas, water, and heat services. Closely comparable to Stadtwerke Altena in scale, geography (Märkischer Kreis / Sauerland), business model, and customer mix of residential and small commercial accounts.

Regional players

• Stadtwerke Werdohl: Municipal utility in the neighboring Sauerland town of Werdohl. Similar small-scale municipal utility model serving a comparable population, though operating in a distinct geographic concession rather than overlapping with Altena.

Broad incumbents

• Mainova AG: Frankfurt-based municipal energy and water utility. Comparable in business model (municipal Grundversorger supplying gas, water, and heat) but substantially larger and serving a major metropolitan area, positioning it as a benchmark rather than a direct competitor.
• Gelsenwasser AG: Large German water utility with municipal shareholders serving much of North Rhine-Westphalia. Comparable in the water supply business — including wholesale water to municipalities — but operates at significantly larger scale and scope than Stadtwerke Altena.
• RheinEnergie AG: Cologne regional utility supplying electricity, gas, water, and heat. Same integrated municipal-utility model as Stadtwerke Altena but operating in a major metropolitan region; useful for understanding how larger peers manage the gas-to-heat-transition challenge.
• Stadtwerke München: Munich's municipal utility providing gas, water, district heating, and e-mobility. Shares the Stadtwerke GmbH model and product mix but at vastly larger scale, useful as a strategic benchmark for how German municipal utilities expand into renewable heat, EV, and digital services.
• Mark-E AG: Regional energy supplier headquartered in Hagen and a 24.9% shareholder of Stadtwerke Altena since 1995. Comparable as a broader Westphalian energy and water utility, but with a larger portfolio and broader geographic reach across the Märkisches Land.

Others

• Enervie Vernetzt GmbH: Gas network operator based in Lüdenscheid that has leased and operated Stadtwerke Altena's gas grid since 2011. Not a direct competitor but a strategic partner and the closest analog for how the gas network layer is organized in the region.
