Tetrag Automation took care of the measurements. The Implenia subsidiary is marketing its own energy monitoring solution “e3m”, which is perfectly suited to high-resolution analyses and consumption data. In January 2018, Tetrag engineers installed new electricity meters and data recorders at the Mannheim site. Even after just a short period of time, it was clear that the
greatest potential for optimisation exists during downtimes – at night and weekends. “We have passed on these findings to our employees and told them to make a conscious effort to switch off the relevant devices”, says Kai Frühbrodt, head of the Mannheim depot. This instruction has been well received from the very start, he says, and has largely been implemented too. This change in behaviour means that the depot can save EUR 5,000 per year just from switching off devices not in use.
