TVIS

TVIS is a heat transmission company in the area of the cities Fredericia, Kolding and Vejle in Denmark. The company buys heat from different producers and distributes it to six local district heating networks supplying heat for 55,000 customers, corresponding to 83,000 households. The heat is mainly delivered from the CHP plant, “Skærbækværket”, the Shell refinery and the waste incineration plant, “Energnisten”. At TVIS energyTRADE is used to plan and optimize how the heat is delivered in the cheapest way.

“Since 2010 we have used the software PRESS to predict the heat demand in our area based on consumption and weather data. With energyTRADE we can also calculate how we get the heat at the lowest cost – and from which producers. As expected, this provides a better overview for the operators that plan the next days’ operation.”        – Mads Kallestrup Petersen, Project Engineer at TVIS.

The 83-km long transmission lines are controlled and monitored 24/7 from a control room. The operators plan how to cover the heat demand in every corner of the network at the lowest possible heat price and energyTRADE is tailored to assist the operators in this task.

“In addition, the system has also proved to be useful when unexpected situations arise. In case of a breakdown at a heat supplier, the system produces recommendations on how to handle the situation in the best and cheapest way – and that’s a great help, which also saves unnecessary expenses in situations where the experience is missing.”            – Mads Kallestrup Petersen, Project engineer at TVIS.
