What Herten municipal works does

Hertener Stadtwerke GmbH is a municipal utility company wholly owned by the City of Herten (Stadt Herten) in the Ruhr area of North Rhine-Westphalia, Germany. Founded in 1900 with the start of gas supply, the company celebrated its 125th anniversary in 2025 and operates as a regulated multi-utility serving residential and commercial customers within the Herten city area.

The company runs an integrated portfolio spanning electricity (Hertenstrom), natural gas (Hertengas), drinking water (hertenwasser, distributed on behalf of GELSENWASSER AG), and district heating (Hertenwärme), alongside newer offerings including photovoltaic systems (PV Action Package with 0% VAT), heat pumps, heating system rentals (Heizung mieten), building thermography, and a public EV charging network. Underlying infrastructure includes approximately 200 local transformer stations with smart-grid remote monitoring capabilities, around 280 km of gas pipe network inspected annually, and approximately five transformer replacements per year. Digital touchpoints comprise an online customer portal, the Meine HSW mobile app on iOS and Android, WhatsApp customer support, and a physical Kundenzentrum in Herten city center. The leisure subsidiary Copa Ca Backum Herten GmbH operates a public swimming pool, spa, sauna, and wellness facility (including Sportbad Westerholt, reopened May 2025).

Revenue is generated across nine streams: regulated network operations (electricity, gas, water) under REMIT and EnWG frameworks, subscription-based energy supply tariffs, district heating subscriptions, photovoltaic system sales, EV charging transaction fees, heating professional services and rentals, measurement services (Messstellenbetrieb), and leisure admissions and gastronomy at Copa Ca Backum. Distribution is direct-to-consumer with no third-party resellers. Strategic positioning emphasises local presence, community engagement (sports sponsorships, energy education programmes), and the Energiewende transition through grid digitisation, renewable integration, and decarbonised heating solutions. CEO Thorsten Rattmann leads the company, which is registered as a GmbH in Germany under HRB 2724.

Direct peers

• Stadtwerke Gladbeck GmbH: Another small Ruhr-area municipal utility operating energy, water and heating networks for Gladbeck residents; near-identical size, scope and concession-driven structure.

• Stadtwerke Marl GmbH: Small Ruhr-area municipal utility providing electricity, gas, water and heating services to the city of Marl; directly comparable in scale, service mix and ownership structure.
• GELSENWASSER AG: Regional water and energy utility that actually delivers water on behalf of Hertener Stadtwerke under Hertenwasser; operates broader water/wastewater networks across the Ruhr area and represents both a key operating partner and a structural peer.
• Stadtwerke Herne AG: Adjacent Ruhr-area municipal utility of comparable size supplying electricity, gas, water and district heating to Herne residents; near-identical business model, regulatory framework and customer profile make it the closest direct comparable.
• Stadtwerke Castrop-Rauxel GmbH: Small Ruhr-area municipal utility serving Castrop-Rauxel with electricity, gas, water and heat; similar scale, product mix and municipal-ownership model to Hertener Stadtwerke.

Broad incumbents

• E.ON SE: Germany's largest energy supplier and network operator, including regional Netzgesellschaften in the Ruhr area; competes with Hertener Stadtwerke for retail customers and increasingly for municipal decarbonisation services.
• RWE AG: Major German energy incumbent with generation, trading and retail activities; a broad-sector comparable rather than a direct retail competitor in Herten, but a relevant reference for valuation and capital-structure benchmarking.
• Stadtwerke Essen AG: Major Ruhr-area municipal utility serving the much larger city of Essen across electricity, gas, water, district heating and public transport; directly comparable business model but materially larger scope and capital base.
