MAIN SUPPLIERS OF HEATTVIS´ heat capacity is approx. 6,000 TJ per year. The main suppliers of surplus heat are the SHELL-Refi-nery in Fredericia and Energnist in Kolding - a waste-to-energy plant treating waste from the cities in the area. DONG Energy’s natural gas fired CHP-plant, Skærbækværket, in Fredericia, is supplying TVIS with the largest volume of energy.

SIX DISTRICT HEATING COMPANIESSix district heating companies in the four cities distribute the heat on be-half of approx. 183,000 citizens. This cooperation has been extreme-ly efficient and stable for the last 30 years.

BIOMASS IN 2018In 2018 district heating will be ba-sed on biomass which will reduce dependency on fossil fuels signi-ficantly. This strategic investment will reduce CO2-emissions by 95 % when a new biomass plant will be in operation.
