Calorific values
To determine the calorific value, the gas composition is determined with the aid of a gas chromatograph at representative points in the GTS transport system.
Not every gas delivery station has its own gas chromatograph. In some cases, one gas chromatograph can serve as many as a hundred gas delivery stations. The gas quality system process description specifies how the calorific value (gas quality) is determined at the transfer points. This document is the description according to articles 2.4.6, 3.2.2 and 3.5.2 of the Metering Code Gas LNB. The table below shows the daily average calorific values for the regional network points over the past 7 days. This page is updated every day.
The user must check for himself whether the above information is suitable for the purpose for which this information is used. GTS is of the opinion that this information cannot be used for:
(On-line) process control, because it concerns a daily average value that is at least one day old. Quality fluctuations can occur on a short time scale.
- Determining the energy flow for contract monitoring, because this monitoring must take place on an hourly basis. GTS provides online information for these purposes.
- Control by private end users of their energy supplier's energy bill. The calorific settlement that is used depends, among other things, on the structure of the regional network operator and the composition of the various categories of customers.
