Do I need an Energy Management System (EMS) to participate in PeakChoice?
No. It may be easier for you to participate in PeakChoice events if you have an EMS, but it is not required. Many customers participate in demand response programs without an EMS; it just may take some extra staff coordination. On the other hand, many modern EMS systems can accommodate pre-programmed settings, such as adjusting the lighting and temperature at all your buildings, during PeakChoice events.
