Gemeindewerke Heusweiler GmbH

What Gemeindewerke Heusweiler GmbH does

Gemeindewerke Heusweiler GmbH (GWH) is the municipal utility company serving the municipality of Heusweiler in Saarland, Germany, operating from its headquarters at Saarbrücker Straße 28. The company is structured as a private limited company (GmbH) under municipal ownership, with Stadtwerke Saarbrücken GmbH as a shareholder and Mayor Thomas Redelberger chairing the supervisory board. It is the statutory drinking water supplier for the municipality and is DVGW-certified (TSM re-certified March 2022) under DVGW Workbook W 1000.

GWH's core operations span five utility services: regulated drinking water supply via a proprietary pipeline network; 100% green electricity and natural gas marketed under the kommpower brand (a cooperative of five Saarland municipal utilities, with gas commodity sourced from Energie SaarLorLux); a biomass- and solar-thermal-powered district heating (Nahwärme) network under development at the Holz water tower; and public EV charging infrastructure at the market square in cooperation with EnergieSaarLorLux. The technology stack is conventional utility infrastructure augmented by digital tooling, including an online customer self-service meter reading portal, tablet-based digital documentation for mandatory water meter replacements, and GPS-coordinated network management. New revenue lines include the 'kommpower mobil plus' green electricity tariff tailored to EV-owning households.

The business model is primarily usage-based and subscription-recurring across regulated and unregulated utility tariffs, with all customers in the Heusweiler catchment. Customer segments include residential households (the primary segment), commercial and small/medium enterprises (with Grossohaus Saar as a named anchor for district heating), and municipal and public institutions. Distribution is anchored by the physical Kundenzentrum and augmented by the kommpower cooperative's shared marketing and procurement infrastructure. GWH is currently investing in a €4.5 million DGNB-certified administrative building (groundbreaking December 2025, completion mid-2027) and is executing a €3 million combined utility renewal project in Friedrichstraße and Auf dem Mühlenberg with municipal partners.
