Electric Rates & Fees

Clark Public Utilities is a customer-owned utility. An elected board of commissioners sets rates. Those rates are based on the cost to provide service within the boundaries of Clark County. There is no profit built in. Electric meters are read monthly and customers receive monthly bills.

Current Rate:

Residential electric rates are 8.16 cents per kilowatt-hour.

A kilowatt-hour equals 1,000 watts of electricity used for an hour. For example, you use a kilowatt-hour when you burn one 100-watt light bulb for 10 hours or a 1,000-watt heater for one hour.

More than 70 percent of an average electric bill reflects the actual cost of the energy you use. We resell electricity for what it costs us to produce it or buy it, with no price mark-up.

Additional Fees:

Cost of Delivery: There is a cost to deliver electricity to your home over our power lines, electric system maintenance and improvements, general administration and overhead, metering, taxes, conservation expenses and other items.

Cost of Service: There is a basic $12 monthly fee that covers the costs of providing service, regardless of whether any electricity used. Such costs include meter reading, billing and the fixed facilities that are in place, including the meter, power lines and transformers.

How Your Energy Is Measured

Demand Metering:

Demand metering is the measurement of average power requirements during a certain time interval. Demand billing consists of measuring a customer’s maximum average load during any demand interval of the billing period.

Metered Demand: The kW as shown by or computed from the readings of the utility’s power meter for the 15-minute period of customer’s greatest use during the month, adjusted for power factor as specified, determined to the nearest kW.

Off-Peak Demand: By special contract with the utility, off-peak demand is available for customers with demands in excess of 30 kW. Service will be available at a discount rate during the off-peak period, which includes all hours except the hours Monday through Saturday between 7:00 a.m. and 10:00 p.m. The off-peak demand rates are 60¢/kW of demand for each kW the off-peak demand exceeds other recorded monthly demands. The energy rate as listed in the

Monthly Rate section applies to all hours.

Power Factor

Power factor is a way of measuring the percentage of reactive power in an electrical system. Reactive power represents wasted energy and is the result of electrical current interaction with inductive loads like motors, transformers, fluorescent lights, arc welders and induction furnaces. Electric systems with many motors exhibit low power factor and increased conductor and transformer losses. Power factor can be improved by the addition of shunt capacitors.

Why improve it?

Improving power factor can reduce power losses and free up the capacity of the existing transmission and distribution equipment for both utilities and end-users. Raising power factor to 95 percent and above is a proven way of increasing the efficient use of electricity. End-users enjoy reduced power bills and improved voltage conditions. The utility benefits from lower line and transformer losses, released system capacity and improved factor.

We have assembled the following additional information on reducing power factor for your use:

Metered real energy measured in kilowatt-hours (kWh) and metered reactive energy measured in Kilovolt Ampere-Hours (kVARh) are used to calculate the average monthly power factor as follows:

    Power Factor = kWh / (square root (kWh squared + kVARh squared))

 


 

General Service: Schedule 34

Applicability: To meet requirements of commercial, industrial and general service customers not provided for in other rate schedules. Rate schedules apply to the sale of electrical energy for the sole and exclusive use of the customer. Any redistribution or resale of electrical energy by the customer must have the approval of the utility.

Character of Service: Sixty-hertz, alternating current. The utility reserves the right to specify the voltage and phase of service supplied under this schedule.

Primary Point-of-Delivery- Single- or Three-Phase Service: A customer having a metered, kilowatt demand consistently averaging 100 kW or more may be served at the primary voltage level (12,470 volts). The customer will be responsible for all costs associated with the primary Point-of-Delivery installation including the metering and primary voltage physical disconnect necessary to isolate the customer’s facilities from the utility’s facilities. The customer will be responsible to own, operate and maintain all electrical distribution facilities on the customer side of the Primary Point-of-Delivery (typically established at the primary meter).

Secondary Points-of-Delivery- Single- or Three-Phase Service: The utility owns and maintains distribution facilities up to the Secondary Point-of-Delivery (typically established at the secondary terminals of the transformer or other designed secondary junction point). If conditions require an overhead service, the utility will install, own and maintain the service and the customer will pay an Aid-to-Construction fee to cover these costs.

In existing installations where there is a mixed ownership of primary distribution facilities beyond a primary meter, the Secondary Point-of-Delivery rate will apply. The ownership and maintenance responsibilities of the customer-owned distribution facilities may be conveyed to the utility subject to utility review and approval. Primary Point-of-Delivery customers paying the higher Secondary Point-of-Delivery rate will be compensated for transformation losses. The metered kilowatt-hours and reactive kilovolt-ampere hours will be reduced 2% before the rates are applied.

  • Sep.- Mar.: 4.91 cents per kWh
  • Apr. – Aug.: 4.38 cents per kWh

Demand charge

$6.77 per kW for secondary point-of-delivery; $5.94 per kW for primary point-of-delivery

Metered Demand: The kW as shown by or computed from the readings of the utility’s power meter for the 15-minute period of customer’s greatest use during the month, adjusted for power factor as specified, determined to the nearest kW.

Off-Peak Demand: By special contract with the utility, off-peak demand is available for customers with demands in excess of 30 kW. Service will be available at a discount rate during the off-peak period, which includes all hours except the hours Monday through Saturday between 7:00 a.m. and 10:00 p.m. The off-peak demand rates are 60¢/kW of demand for each kW the off-peak demand exceeds other recorded monthly demands. The energy rate as listed in the Monthly Rate section applies to all hours.

Adjustment of Demand for Power Factor: Demands will be adjusted to correct for average power factors lower than 95%. Such adjustments will be made by increasing the measured demand 1% for each 1% or major fraction thereof by which the average power factor is less than 95% lagging.

Metered real energy measured in kilowatt-hours (kWh) and metered reactive energy measured in Kilovolt Ampere-Hours (kVARh) are used to calculate the average monthly power factor as follows:

    power factor = kWh / (square root (kWh squared + kVARh squared))

Water Rates & Fees

Water meters are read every other month. Our water utility serves the Hazel Dell, Felida and Salmon Creek areas, as well as Hockinson, Yacolt, Amboy and some other smaller unincorporated geographic areas, primarily in the north part of the county. Clark Public Utilities’ water rates structure complies with a law passed by the Washington legislature that requires utilities to do more to encourage water conservation.

Current Rate:

To encourage conservation, pricing is in three tiers with the cost per 100 cubic feet increasing as more water is used. The price of water is measured by cubic feet. One cubic foot is 7.48 gallons. The average family of four uses 400 gallons of water a day.

  • Block 1: $1.85 per 100 cubic feet (748 gallons), for up to 1,800 cubic feet of use
  • Block 2: $2.40 per 100 cubic feet (748 gallons), for 1,800 – 3,600 cubic feet of use
  • Block 3:  $2.95 per 100 cubic feet (748 gallons), for more than 3,600 cubic feet of use

Additional Fees:
There is also a monthly customer charge which is based on the size of the water meter serving your property. For most residential customers this charge is $9.00 a month.

Clark Public Utilities water service territory covers mostly unincorporated portions of the county not served by city-owned water systems.

Water rates were adjusted February 1, 2012. Please click here to view the current rates.

Water is billed by cubic feet used. A cubic foot is about 7.5 gallons. The monthly basic service charge varies depending on the size of the meter.
