ℹ Enter 12 months of energy document data. Actual PF = power factor recorded on bill. Measured Demand = peak kW demand. Demand Rate = $/kW charge rate (from tariff/rate schedule, not total bill amount).

∑ Formula Reference
BD = PD × (1 + 0.65×(PFb−PF)) if PF < PFb
BD = PD × (1 − 0.50×(PF−PFb)) if PF ≥ PFb
DOPC = BD × DR
kVAractual = kWavg × √((1/PF)²−1)
kVAradj = max(0, kVAract − kVArcap)
PFadj = kWavg / √(kW²+kVAradj²)
ACS = Σ(DOPCact − DOPCadj)
IC = kVAr × $/kVAr × (1+tax%) + Install
Payback = IC / ACS
PD = measured peak demand (kW from bill).
kWavg = energy (kWh) / hours in month.
BD = billed demand after PF adjustment.
DR = demand rate ($/kW) - from rate schedule.
