Fernwärmeversorgung Niederrhein GmbH

What Fernwärmeversorgung Niederrhein GmbH does

Fernwärmeversorgung Niederrhein GmbH (FN) is a municipal district heating utility founded in 1966 and headquartered in Dinslaken, Germany, supplying thermal energy for space heating and domestic hot water to connected buildings via a closed-loop network of pre-insulated underground pipes. The company serves more than 60% of Dinslaken households and nearly all public buildings in the city, with additional supply areas in Moers, Voerde, Dortmund (Scharnhorst, Bodelschwingh, MSA-Siedlung), Krefeld, Hünxe-Bruckhausen, Hennstedt (Schleswig-Holstein), Laubach (Hesse), and Illingen (Baden-Württemberg); total network length exceeds 700 km with 100+ MW of connected capacity.

Heat is generated from a diversified mix including high-efficiency combined heat and power (CHP) plants, recovered industrial waste heat from the metal industry, biomass and biomethane CHP units, and — under exploration since 2024 — deep geothermal sources through the Dinslaken-Voerde-Hünxe permit and the 1,640 sq km 'Erdwärme Metropole Ruhr' consortium. At customer premises, a compact transfer station separates the district heating circuit from the building installation via a heat exchanger, eliminating the need for customer-owned boilers, fuel storage, or chimneys.

Revenue is generated through a regulated three-component pricing model: a consumption-based Arbeitspreis (ct/kWh), a fixed Jahresgrundpreis for heat generation capacity, and a Verrechnungspreis for metering and billing, with semi-annual indexation in April and October. FN sells exclusively through direct channels — own customer center, toll-free hotline, 24/7 emergency line, a self-service online portal, and field sales representatives covering specific supply areas. Ownership rests with Stadtwerke Dinslaken GmbH (70%), ENNI Energie & Umwelt Niederrhein (15%), and Stadtwerke Duisburg AG (15%), with all personnel employed at Stadtwerke Dinslaken.

Revenue model

1. District Heating Energy Supply: Core revenue from supplying thermal energy (heating and hot water) to connected buildings. Customers pay based on consumption (Arbeitspreis in ct/kWh), plus fixed annual basic price (Jahresgrundpreis) for heat generation capacity and billing price (Verrechnungspreis) for measurement and billing services. Prices adjusted semi-annually (April and October).
2. Connection and Infrastructure Services: Revenue from new connections, connection modifications, and infrastructure services. First contract term typically 10 years for supply contracts. Installation services for heat transfer stations and house connections.

Core offering

Fernwärmeversorgung Niederrhein GmbH (FN) supplies thermal energy (district heating for space heating and domestic hot water) via a closed-loop underground pipe network of over 700 km to residential, commercial, and public buildings across multiple German regions. Heat is sourced from combined heat and power plants, industrial waste heat recovery from the metal industry, biomass and biomethane cogeneration plants, with planned geothermal exploration. Customers receive heat via compact transfer stations at their premises, eliminating the need for individual heating equipment.

Product overview

Fernwärmeversorgung Niederrhein GmbH (FN) operates a district heating (Fernwärme) network across multiple German states — primarily in North Rhine-Westphalia (Dinslaken, Moers, Voerde, Dortmund, Castrop-Rauxel, Krefeld, Hünxe-Bruckhausen), but also in Schleswig-Holstein (Hennstedt), Hesse (Laubach), and Baden-Württemberg (Illingen) — delivering thermal energy (heating and hot water) through insulated underground pipework to end customers via compact transfer stations. The company's core product is its district heating supply service, sourced from a diversified energy mix: high-efficiency combined heat and power (CHP), recovered industrial waste heat, biomass/biomethane CHP plants, and, in future, geothermal energy. FN's customer-facing digital products include the Kundenportal (customer portal) — a 24/7 online self-service platform for account management, invoice access, and meter reading submission — and a set of online service forms for registration, deregistration, SEPA mandate setup, and meter reading communication. An educational blog (Gut zu wissen) complements the digital customer experience by explaining billing, energy factors, and sustainability topics.
