E400* Series

This rate applies to commercial accounts with average monthly demand of 750 kilowatts (kW) or greater. This rate includes:

  • Electric energy - Total amount of electricity used in a month (measured in kWh), plus fixed charges for metering and billing
  • Facility demand - The facility's highest one-hour average demand during the billing period, or 75% of the highest demand for the previous 11 months. (Facility demand charges cover the cost of the operation, maintenance and replacement of the electric distribution system used to serve customers. The greater the demand each customer requires of the electric system, the greater the cost to operate, maintain and replace the electric distribution system.)
  • Coincident peak - The facility's demand for electricity during the time when electricity demand systemwide is highest
