Net Metering

INTRODUCTION AND REQUIREMENTS

Net Metering is a service that measures the difference between the electricity you consume from Cheyenne Light, Fuel & Power and the electricity your qualifying facility generates and feeds back into the electric grid. To qualify for Net Metering you must meet each of the requirements listed below.

Net Metering Requirements

  • Generating facility must have a design capacity of 25 kW or less.
  • Generating facility must use as its fuel solar, wind, biomass, or hydropower.
  • Generating facility must be located on the Customer’s premises.
  • Generating facility must operate in parallel with the Company’s transmission or distribution facilities.
  • Generating facility must be intended primarily to offset part or all of the Customer’s requirements for electricity.
  • Customer must complete the application process.
  • Customer must comply with all interconnection guidelines (Inverter must be UL 1741 or IEEE 1547 qualified).

NET METERING BILLING EXAMPLE

You have a 2 kW wind turbine that runs 8 hours a day at rated speed. This will generate 16 kWh a day or around 480 kWh per billing cycle. During the 8 hours a day that the wind turbine is generating electricity, you are consuming (refrigerator, freezer, computer, electronics, etc.) a portion of that electricity even if you are not home and have your lights off. Of the 480 kWh generated during the billing cycle 360 kWh were consumed and 120 kWh were put back into the distribution system. For the 16 hours a day that your wind turbine is not generating and the times when you are consuming more than you’re generating you use 340 kWh from the distribution system.

Your bill for this billing cycle would be:
Net Energy = Energy Consumed – Energy Produced
                     = 340 kWh – 120 kWh = 220 kWh

Energy Charge: 220 kWh * 0.08333 = $18.33
Service and Facility Charge: $12.00
Franchise Fee: 30.33 * 0.02 = $0.61 (Not Applicable in the County)
Sales Tax: 30.94 * 0.05 = $1.55
Total Bill Due: $32.49

If in our example you had excess generation of 400 kWh (instead of 120 kWh), you would only be billed a $12.00 Service and Facility Charge for that billing cycle. In addition, the net energy (340 kWh – 400 kWh = -60 kWh) would be credited to your next bill. At the beginning of each calendar year, any remaining unused kWh credit accumulated during the previous year shall be sold to Cheyenne Light, Fuel & Power at the Company’s Standard Rate for Purchasing Power from Qualifying Small Power Production or Cogeneration Facilities.
