We have been using Inergy Systems’ demand control system for a couple of years now and it has worked great in managing our utility needs.  The app and software will alert you during any on-peak exceedances to help prevent an increase on your utility bill.  The app presents an easy-to-read display of what the system is doing to reduce your peak usage of electricity and save you money.  It also allows easy adjust to override any setting when needed.  With our solar system and the demand manager our peak summer utility bills are almost cut in half compared to before having solar and the Inergy demand manager.  Highly recommend this system for saving on peak summer utility bills.
