Kalundborg Forsyning

What Kalundborg Forsyning does

Kalundborg Forsyning A/S is a Danish regulated utility company headquartered at Dokhavnsvej 15 in Kalundborg, providing drinking water, district heating (fjernvarme), wastewater and sewage management, surface water for industry, and district cooling (fjernkøl) to residential, commercial, and industrial customers within the Kalundborg municipality service area. The company operates water supply networks, the Kalundborg Central Renseanlæg and Tjørnelunde Renseanlæg wastewater treatment plants, plus what is described as Nordic Europe's largest industrial district cooling and heating central. Technology highlights include a separatkloaksystem (separate sewerage system) for rainwater and wastewater separation, online measurement stations for industrial surface water, and a wastewater-to-green-district-heating conversion process tied to the Kalundborg Symbiosen industrial symbiosis network.

Revenue is generated through regulated, usage-based tariffs across the core utilities (water, heating, wastewater) billed monthly, plus a step-model wastewater tariff for businesses, transaction-based fees for septic tank emptying, and dedicated industrial rates for surface water and district cooling. Pricing is published and regulated, with a 40% reimbursement mechanism for customers disconnecting rainwater from public sewers. The company is structured as a Danish public limited company (A/S) with 51-100 employees, holding ISO 14001, 9001, 45001, 50001, and 27001 certifications and led by Director/CEO Hans-Martin Møller. Customer engagement runs through the 'Min Forsyning' self-service portal, SMS service, e-Boks digital delivery, and Betalingsservice automatic payment integration.

Recent activity includes the 2026 groundbreaking on expansion of the Kalundborg Central Renseanlæg (with associated VVM environmental assessment), a designated 2025-2026 strategy year, and a temporary administrative relocation to Gyproc facilities from August 2026 during headquarters renovation. The firm holds exclusive franchise rights within its service territory, which materially constrains competitive risk but also caps addressable geography absent regulatory change.
