Energy Monitoring System EnMos - Swisscom

Short description

Acting as the total contractor, Tetrag implemented an energy monitoring system for 67 data centres and hubs belonging to Swisscom. This included the concept development, planning, meter installation and system integration.

The project

The existing measurement infrastructure at the various locations was inspected and upgraded. New data sources were connected, while interfaces had to be established with other management systems.
