At the day of Go Live, Enersee detected an anomaly in the energy consumption patterns within a large building. The anomaly had been active for over 3 months at that point, and had not been detected by the >30 people facility management team on site.
The very anomaly was a broken Relay, resulting in a bypassed PID controller towards a Variable Speed Drive. This resulted in a spiking Energy cost of €8000/month.
The Enersee root cause analysis resulted in a fix within the week, next to a list of other issues appearing the next few months (not being detected by the "Classic" EMS).
Who knows how much longer this Relay would have remained broken without Enersee's detection.
