Stadtwerke Ratingen

What Stadtwerke Ratingen does

Stadtwerke Ratingen GmbH is a German municipal utility (Stadtwerke) founded in 1976 and headquartered in Ratingen, North Rhine-Westphalia, serving approximately 87,000-92,000 residents of the City of Ratingen and surrounding commercial customers. The company provides an integrated multi-utility portfolio including electricity (100% certified green electricity, or Ökostrom, since 2021), natural gas, drinking water and wastewater disposal, district heating (Heimat.Wärme), public EV charging infrastructure, solar PV and storage solutions, mini-PV balcony systems, and heat-pump tariffs. Beyond core energy and water services, Stadtwerke Ratingen operates four municipal swimming facilities (Allwetterbad Lintorf, Sauna Lintorf, Freibad Angerbad, and Hallenbad Angerbad) and delivers fiber-optic internet, telephone, and television through its wholly owned subsidiary KomMITT Ratingen GmbH. Grid and network operations (electricity, gas, fiber, water) are managed through a second wholly owned subsidiary, Netze Stadtwerke Ratingen, which also operates the smart metering/Messstellenbetrieb infrastructure.

Underlying technology includes smart-meter infrastructure compliant with §14a EnWG for controllable consumer devices, a digital Netzanschlussportal for standard network connections under §§6, 19 NAV, a fiber-optic network (Glasfaser), and 24/7 grid operations. Stadtwerke Ratingen uses third-party tools for non-core functions: hsag Heidelberger Services AG (with Onlim as data processor) for chatbot-based customer support, e-pilot GmbH for guided online ordering, Surveymonkey for customer surveys, Brevo for newsletter management, Chargecloud for EV charging management, and EyeAble for accessibility.

The business model is anchored in recurring subscription revenue from energy supply, water, and district heating contracts, complemented by usage-based EV charging fees, transactional ticket sales for swimming facilities, and subscription fiber-optic services. Go-to-market is hybrid: a physical customer service center (Heimat.Kontor) for in-person sales and consulting, an online customer portal and tariff calculators for self-service, telephone customer service, dedicated enterprise field sales for large commercial and industrial customers (Großkunden), and an e-commerce shop (shop.ratinger-baeder.de) for bath tickets. Primary customer segments are residential households in Ratingen and a smaller commercial/industrial (Großkunden) tier; the City of Ratingen is also the majority shareholder. Ownership is mixed public-private: majority City of Ratingen, minority Rhenag (Rheinische Energie AG, Cologne). The company holds TÜV Nord certification for 100% Ökostrom, TÜV Süd asset-management certification, ISO/IEC 27001, and TSM/ISMS certifications (2021-2024).
