Rate calculations of Cost are not enabled in this version of BEMS. Since this Active Power field is only used in Rate calculation of Costs, it is not currently useful.
Active Power is the current kW (Kilowatts). This is current Rate from the meter used to measure Active Energy. The current value is read every 15 minutes and entered in the BEMS database.
Active Power is optional. It is needed only if your Electric Rate requires for calculating the Cost of Power and you want to calculate Power Costs. It does not show directly on any BEMS display or report. It is shown indirectly only if used in calculating costs.
