Energy metering in Brussels (STIB)

STIB has smart meters for its high-voltage electricity network (11kV) located at the substation level. They allow a daily monitoring of the global energy consumption both for traction and buildings. This information is sent to the technical and finance departments for evaluation. However, these meters have not provided sufficient information for a precise analysis of the consumption per building or equipment and STIB previously produced only monthly statements for the local energy meters.

The new energy-metering scheme implemented by STIB aims to provide more accurate and granular consumption data by automating readings. This energy management system allows checking of the consumption every 15 minutes and gives a curve of the consumption over 24 hours, all year long. STIB also uses software, where data (gas, electricity and water) are encoded manually on a monthly basis.

This tool is useful for visualisation and enables comparison of the effective energy consumption with the energy bills received from the supplier. However, the lack of automation is problematic, due to the risk of errors and the unavailability of data when staff is on holiday. Hence, in the scope of the T2K project, STIB is investing in new energy-metering software, which will offer a far more detailed monitoring of the electricity, gas and water consumption.
