Stadtwerke Troisdorf

What Stadtwerke Troisdorf does

Stadtwerke Troisdorf GmbH is a municipal utility (Bürgerstadtwerk) headquartered in Troisdorf, Germany, founded in 1904 as the local water and gas works. It supplies electricity, natural gas, drinking water, and geothermal district heating (TroGeo) to the city of Troisdorf and surrounding region, operating as the regulated default supplier (Grundversorger) for electricity, gas, and water in its concession area. All electricity tariffs are sourced 100% from Norwegian hydropower under continuous RenewablePLUS certification since 2015. The company serves residential, commercial, industrial, and housing-industry customers, and additionally offers adjacent services including e-mobility charging infrastructure (with TankE network integration and a THG quota annual bonus), fiber optic connectivity for businesses (via Jeti-Line partnership), submetering and heating-cost billing for the Wohnungswirtschaft segment, dynamic electricity tariffs, and renewable-energy contracting (solar PV leasing, heat pump leasing, CHP/BHKW, geothermal) under a no-upfront-capital Pacht model.

The business model combines usage-based commodity revenue from electricity, gas, and water sales; subscription/contracting revenue from heating and renewable equipment leasing; regulated network and metering operations revenue; and managed-services revenue from submetering and digital meter reading (iMSys). Customer acquisition is executed through a physical customer center, a self-service Kundenportal and Netzanschlussportal, a dedicated field sales team for industrial and commercial clients (offering tranche and spot procurement models), and multi-channel community engagement (TroWOW! loyalty program, TroCARD, Tro4me app, inTro magazine, regional sponsorship). Infrastructure includes approximately 400 km of sewer network operated via the related municipal entity Abwasserbetrieb Troisdorf, smart metering with remote reading, a geothermal heating network across multiple districts, and digital platforms for contract and connection management.

Ownership is structured as a public-owned GmbH: citizens of Troisdorf are the ultimate owners, with rhenag (Rheinische Energie Aktiengesellschaft, a subsidiary of RheinEnergie AG) as the major institutional shareholder following the 2023 Rheinlandkooperation restructuring. Since 2019, the company has been led by a Doppelspitze of Andrea Vogt and Michael Roelofs. Related municipal entities include TroiKomm GmbH, IPTro GmbH, TroPark GmbH, Aggua Troisdorf GmbH, öPA Verkehrsgesellschaft mbH, Abwasserbetrieb Troisdorf AöR, and Stadtsolar Troisdorf AG.
