Primary Time-of-Use (CP1)


This rate plan is available to customers with service at approximately 3,810 volts or higher and to customers who own their own transformation equipment.

How it works

On-peak option hours are 8 a.m. to 8 p.m. or 10 a.m. to 10 p.m. The monthly minimum charge is the facilities charge plus either the charge for 300 kilowatts (kW) of billed demand or the minimum demand charge stated in a customer contract, whichever is greater, plus the customer maximum demand charge.
