Tårnby Forsyning

What Tårnby Forsyning does

Tårnby Forsyning is a Danish municipal utility company wholly owned by Tårnby Kommune (Tårnby Municipality), operating under the legal entity TÅRNBY FORSYNING Holding A/S and four wholly-owned subsidiaries (Vand A/S, Spildevand A/S, Varme A/S, Service A/S) established following 2010 Danish water sector legislation that mandated separation of water supply from municipal government. The company delivers four integrated utility services: drinking water supply, wastewater collection and treatment, district heating, and district cooling, to all properties within Tårnby Municipality, located in Kastrup near Copenhagen.

Core technology infrastructure includes 75 pump stations operating 24/7, a wastewater treatment plant at Kastrup Strandpark, district heating pipe networks with Isoplus Pipeguard monitoring providing 50 cm fault localization precision, and a wastewater-sourced heat pump system (4.3 MW cooling / 6.5 MW heating) paired with Denmark's first 2,000 m³ cold water accumulator tank. In 2025, Tårnby Forsyning is deploying smart remote-readable water meters (9,500 units) and heating meters (up to 12,000 units) supplied by Saint-Gobain and installed by Eltel Networks, enabling real-time consumption tracking via the Smart Forbrug customer portal and mobile app. Climate adaptation infrastructure includes a 5,000 m³ stormwater basin in Travbaneparken inaugurated in 2021.

The business model operates under a regulated monopoly framework with publicly disclosed, usage-based pricing. District heating operates under the non-profit 'hvile-i-sig-selv' principle by Danish law, while water and sewage follow regulated tariff structures. Revenue streams include subscription-based water, sewage, and heating services to approximately 20,000+ residential households (district heating covers roughly half of the municipality's 40,000+ households), one-time connection fees for new district heating customers, and commercial district cooling supply to the Scanport business area serving tenants including Ferring Pharmaceuticals and Scandic Hotel. The current strategic focus is a major district heating expansion targeting approximately 8,000 additional household connections, driven by Denmark's natural gas phase-out mandate by 2035, executed in staged phases (Etaper 2–8+) using contractors Munck Forsyningsledninger and Nordkysten, with heat primarily sourced from CTR (Centralkommunernes Transmissionsselskab I/S).

The company owns and operates an extensive underground pipe network, 75 pump stations, and a wastewater treatment plant at Kastrup Strandpark, which doubles as an energy hub producing combined heating and cooling via heat pumps on treated wastewater.

Product overview

Tårnby Forsyning is a multi-utility company operating four core service areas: water supply (Vand), wastewater management (Spildevand), district heating (Fjernvarme), and district cooling (Fjernkøl) — all serving Tårnby Municipality. The company operates under the non-profit 'hvile-i-sig-selv' principle mandated for Danish district heating. Its current major initiative is a large-scale district heating expansion (2022 onward) targeting ~8,000 new residential and commercial connections, executed in timed phases (Etaper 2–8+). This is supported by a new heat pump at Ugandavej and heat supply from CTR. The wastewater treatment plant at Kastrup Strandpark doubles as an energy hub, hosting heat pumps that produce both district heating and district cooling for the Scanport commercial area. Supporting products include smart remote-readable water meters (2025 rollout), a customer portal and Smart Forbrug mobile app for consumption monitoring, pipe monitoring technology (Isoplus Pipeguard), and a Peace-of-Mind Scheme (Tryghedsordning) for customers awaiting connection. The company also operates climate resilience infrastructure, including a 5,000 m³ stormwater basin in Travbaneparken.
