Trekantområdets Varmetransmissionsselskab

What Trekantområdets Varmetransmissionsselskab does

Trekantområdets Varmetransmissionsselskab (TVIS) is a Danish municipally owned heat-transmission company headquartered in Fredericia. Founded in 1982 and structured as an interkommunalt selskab (I/S), it is jointly owned by the municipalities of Fredericia, Kolding, Vejle and Middelfart, and operates the principal district-heating transmission corridor across the Trekantområdet region. The pipeline network spans roughly 83 km and connects nine downstream district-heating companies serving approximately 60,000 end consumers (~115,000 household equivalents).

TVIS's business model is wholesale heat transmission: it does not own end-customer relationships but charges throughput tariffs to the connected distribution utilities and industrial process-heat customers. The company sources heat from a diversified, predominantly CO2-neutral mix — including biomass-converted CHP output from Ørsted Skærbækværket (in which TVIS holds a 1.5 billion DKK ownership share), waste-heat streams from Crossbridge Energy's refinery and from Everfuel's HySynergy PtX facility, biomass and electric sources via Energnist — achieving 90.7% CO2-neutral sourcing in 2023. New planned assets include a 20 MW electric boiler with thermal storage in Middelfart scheduled for April 2026.

Revenue mechanics are volume-based transmission tariffs; the company funds heavy capex through municipal-owner equity and long-dated debt, including a 228 million DKK Kommunekredit loan (2020) and a 534 million DKK three-year investment programme adopted in 2023. Recent strategic additions include the first new downstream DHC connections since founding (Vamdrup, Jelling, Bredsten-Balle, Strib, Kolding Nord) and industrial process-heat contracts with Arla Taulov, European Protein, Moveero and Gartneriet Gårslev. Governance is anchored in ISO 55001 (asset management, 2022) and ISO 27001 (information security, 2024) certifications.

Revenue model

1. Heat Transmission to District Heating Companies: TVIS transmits heat from production sources (biomass plants, waste heat, industrial excess heat, PtX) through its 83km transmission network to nine connected district heating (fjernvarme) companies. Revenue is derived from heat tariffs charged to these wholesale customers, who then distribute to end consumers. The model is consumption-based and volume-driven, with stable long-term contracts.

Core offering

TVIS operates an 83-kilometer district heating transmission pipeline network across four Danish municipalities (Fredericia, Kolding, Vejle, and Middelfart), transmitting heat from biomass plants, industrial excess heat, waste heat, and Power-to-X facilities to nine connected district heating companies and direct industrial process heat customers. The company also supplies process heat to industrial manufacturers (dairy, foundry, agriculture, horticulture, hospitality) and operates heat exchanger stations, electric boilers with thermal storage, and SCADA-controlled operations.

Product overview

TVIS (Trekantområdets Varmetransmissionsselskab) operates as the backbone district heating transmission company for the Triangle Area of Denmark, covering Fredericia, Kolding, Vejle, and Middelfart municipalities. The company manages an 83-kilometer transmission pipeline network that distributes heat to nine district heating companies and directly to industrial customers. The core product is the transmission pipeline infrastructure, supported by heat exchanger stations, electric boilers, and thermal storage facilities. TVIS connects multiple heat sources including biomass (Skærbækværket), waste heat (Energnist), excess heat from industry (Shell/Crossbridge, Everfuel), and Power-to-X facilities. The company offers process heat supply to industrial customers, excess heat recovery services, maintenance and asset management, CO2 calculation services, and supply mapping. TVIS participates in the Triangle Energy Alliance for Power-to-X development. The company invests approximately 500 million DKK over three years in network expansion, process heat projects, and excess heat initiatives.

Direct peers

• Verdo: Verdo is a Danish green energy utility headquartered in Randers, producing and distributing district heating, electricity, and fiber. Verdo and TVIS have an existing collaboration (custom pressure-holder system in Kolding), and Verdo's heat business is directly analogous: green heat production, transmission, and process heat to industrial customers in a defined Danish region.
• Aarhus Kommunes Varme: Aarhus Kommunes Varme supplies district heating across Aarhus, Denmark's second-largest city, with a mix of biomass, waste heat, and CHP sources. Comparable to TVIS as a municipal district heating utility in a major Danish city, focused on decarbonized heat supply and conversion of natural gas customers to district heating.
• HOFOR: HOFOR is Copenhagen's multi-utility (water, wastewater, district heating, gas, cooling) with a large district heating transmission and distribution network. Comparable to TVIS as a Danish, municipally-owned regulated heat utility operating in a defined regional catchment and supplying both residential and process heat customers.
• CTR (Centralkommunernes Transmissionsselskab): CTR operates the largest district heating transmission network in the Copenhagen area, transmitting heat from production sources to local distribution companies. Directly comparable to TVIS in business model: regulated municipal transmission utility, wholesale heat tariffs, SCADA-controlled pipeline network, and multi-municipal ownership. The structural and operational analog is the closest peer for TVIS.
• Aalborg Varme (Aalborg Kommunes Forsyning): Aalborg Varme is one of Denmark's largest district heating utilities, supplying the Aalborg municipality with combined heat and power. It is comparable to TVIS as a municipally-owned Danish district heating utility with CHP/biomass sourcing and industrial process heat customers, though at a meaningfully larger scale.

Regional players

• DIN Forsyning: DIN Forsyning is a multi-utility covering water, wastewater, heating, and waste in southwestern Denmark (Esbjerg, Varde, Fanø). Comparable to TVIS as a Danish municipal utility active in district heating and the green transition, though it serves a different geographic region and has a broader service portfolio beyond heat transmission.

Broad incumbents

• E.ON Denmark (formerly E.ON Varmeløsninger): E.ON Denmark is a major utility group active in electricity, gas, and district heating solutions across multiple Danish municipalities. Comparable to TVIS as a competing provider of municipal heat and energy services, though at broader national scale and as part of a European utility group rather than a local municipal partnership.
• HMN Naturgas: HMN Naturgas is a Danish natural gas distribution utility now repositioning toward green gas, district heating, and renewable heat solutions. Comparable to TVIS as a regulated Danish energy utility serving municipalities and end customers, though its core legacy asset base is natural gas rather than district heating transmission.
• Norlys (formerly SE/EnergiMidt): Norlys is one of Denmark's largest multi-utility cooperatives, with significant heat, electricity, fiber, and gas operations. Comparable to TVIS at a category level as a Danish energy utility active in district heating and the green transition, but much larger and diversified across many regions and services.
• Ørsted (Heat & Power): Ørsted is both a major Danish heat/power producer and TVIS's largest heat supplier via Skærbækværket biomass. Comparable at a category level as a major Danish energy producer participating in biomass-to-heat and Power-to-X, though Ørsted's scale, scope (offshore wind, bioenergy, gas), and listed-company status make it a broader incumbent rather than a direct peer.
