Stadtische Werke Netz + Service

What Stadtische Werke Netz + Service does

Städtische Werke Netz + Service GmbH (NSG) is a municipal network operator and infrastructure service provider headquartered in Kassel, Germany. It is a wholly owned subsidiary of Kasseler Verkehrs- und Versorgungs-GmbH (KVV), itself owned by the City of Kassel. NSG operates the regulated electricity and gas distribution networks in Kassel and surrounding North Hesse, comprising approximately 2,953 km of electricity lines, 1,200 km of gas pipelines, and 1,300+ km of water pipelines (the latter on behalf of KASSELWASSER, the municipal water utility). The company serves more than 250,000 residents and commercial customers, with a portfolio that includes metering services under the Messstellenbetriebsgesetz, public lighting operation for the City of Kassel, and a growing fiber optic (FTTH) business operated under the viyonet brand.

The company's revenue model combines regulated network access charges (set by the Bundesnetzagentur and Regulierungskammer Hessen), managed-service fees for water distribution on behalf of KASSELWASSER, recurring metering services, and emerging wholesale and retail fiber optic revenues. Distribution channels include a direct customer service center, online self-service portals (Plusportal, Wasserportal, viyonet Cloud-Portal), a certified installer network, and a strategic partnership with Deutsche Telekom for FTTH retail service delivery. NSG also provides Smart City infrastructure (LoRa-WAN IoT) supporting intelligent parking, waste management, and lighting use cases.

NSG is investing in product expansion and digital transformation, launching products including hydrogen demand registration, EV charging infrastructure support, §14a EnWG grid-flexibility services, and rooftop solar feed-in management. Recent strategic activity centers on the 2023 Deutsche Telekom FTTH partnership (targeting 142,000 households by 2033) and the launch of digital customer portals. The company's competitive position rests on its regulated monopoly franchise, embedded physical infrastructure, and stable public ownership under municipal governance.
