Doesn't Duke Energy Carolinas change my rates every year?

A customer's electric bill is made up of two primary components: the base rate and the fuel rate. The base rate covers the company's cost to operate and maintain the electric system, including the opportunity to earn a fair profit for investors. Base rates are adjusted periodically to more closely align the rates paid by customers with the company's costs to serve them.

The fuel component, which increases or decreases annually, covers the company's costs for coal, natural gas, uranium and other fuel-related items to keep our power plants running. The prices reflect the actual costs the company incurs to fuel its power plants. The fuel rate is a pass-through to customers and doesn't include any profit.
