Secondary-voltage commercial and industrial schedules (Cg 2, Cg 3, Cg 3S, Cg 3C) have no power-factor adjustment in the tariff.

The power-factor rule

Cp 1 General Primary time-of-use (the same formula appears in Cp FN, Cp 3, Cp 3S and Cp 4)

Applies to: Three-phase primary service (about 3,810 V and up), with a monthly minimum billed on-peak demand of 300 kW.

How it works: On-peak billed demand is adjusted by the peak-period power factor (from kWh and lagging kVARh). Below 85%, billed demand rises; above 85%, it falls. Under Cp FN there is no credit for leading power factor.

Formula: Below 85%: billed on-peak demand = measured × [1 + 0.65 × (0.85 − PF)]. Above 85%: measured × [1 − 0.5 × (PF − 0.85)].

Example: Illustration of the adjustment only: at 0.75 PF the multiplier is 1 + 0.65 × 0.10 = 1.065, so 6.5% more on-peak demand is billed. At 0.95 PF it is 1 − 0.5 × 0.10 = 0.95, so 5% less. Your actual bill also depends on firm and non-firm demand, off-peak comparisons and minimums. Illustration, not a bill estimate; billed demand, measurement intervals, minimums and credits determine the actual adjustment.

"Billed on-peak demand = (measured on-peak demand) [1 + (0.65)(0.85 - peak power factor)]"
