The Access Charge is a fixed monthly charge that partially offsets the cost of transformers, power lines, meters, service lines, emergency services, and billing processes that are required to provide each Customer with access to electric power service. These costs exist even if a Customer uses no power during the month.
The Energy Charge is the cost of the electricity used to power everything in your home. Your individual electric meter measures your energy use in units called kilowatt-hours or kWh. For example, if you run a light bulb rated at 100 watts for ten hours, it would use 1,000 Watt-hours or one kilowatt-hour (1 kWh). It is calculated using the formula:
Energy Charge = Your Metered Usage x Energy Rate
The FCA Charge (Fuel Cost Adjustment) is set by the Tennessee Valley Authority and refers to the cost of the fuel TVA uses to generate power (coal, natural gas, nuclear fuels, etc.) It may increase or decrease slightly based on TVA's fuel costs. For more information on TVA's Fuel Cost Adjustment visit TVA Monthly Fuel Costs. It is calculated using the formula:
FCA Charge = Your Metered Usage x FCA Rate
