The power-factor rule
Madison Gas and Electric (MGE) Power-factor rule confirmed
Ordinary commercial and industrial customers have no power-factor charge. One transmission-voltage interruptible schedule adjusts billed demand if low power factor isn't corrected after notice.
Cp-1 C&I High Load Factor Direct Control Interruptible Service for Transmission Voltage. Applies to: Service at 69 kV or higher, interruptible demand above 10,000 kW, annual load factor of at least 90%. After written notice, if corrective equipment isn't installed within 240 days, on-peak billed demand is scaled by 85% divided by the actual power factor. Billed on-peak kW = registered on-peak kW × (0.85 / actual PF).
