P s=P ab-P r
In formula:
P sMaximum economize on electricity power before and after-Energy-saving Projects is implemented;
P abThe power consumption of device parameter under statistical report phase load condition before the-project implementation;
P rThe power consumption of device parameter under statistical report phase load condition after the-project implementation.
