Duke Energy bills contain multiple line items that can be confusing at first glance. This guide breaks down each charge so you can understand exactly what you're paying for.
Basic Service Charge (Customer Charge)
This fixed monthly fee covers the cost of maintaining your connection to the grid — your meter, the service line to your home, billing systems, and customer service. It appears on your bill regardless of how much electricity you use.
- Duke Energy Florida: ~$12-13/month
- Duke Energy Carolinas SC: $11.96/month
- Duke Energy Carolinas NC: $14.00/month
- Duke Energy Progress: Varies by state
Energy Charge
The energy charge is the per-kWh rate multiplied by your usage. This is the largest portion of most bills. On Duke Energy bills, this may be shown as:
- A single line item
- Broken into base energy and fuel components
- Tiered rates where the per-kWh charge changes based on usage levels
Fuel Cost Recovery
This charge covers Duke Energy's actual cost of fuel used to generate electricity. It's shown separately from the base energy charge because it fluctuates with fuel market prices.
In Florida, this appears as a distinct line item. In the Carolinas, fuel costs may be embedded in various riders. See our fuel charge guide for details.
Riders and Adjustments
Duke Energy bills, especially in the Carolinas, include multiple "riders" — additional per-kWh charges that recover specific costs:
- Storm Cost Recovery: For hurricane and ice storm repairs
- Grid Improvement: For infrastructure upgrades
- Renewable Energy: For solar and wind investments
- Demand Side Management: For energy efficiency programs
Each rider is approved by state regulators and appears as a separate line item or is bundled into an "adjustments" section.
Taxes and Fees
Your bill includes various taxes and government-mandated fees:
- State sales tax (varies by state)
- Local/municipal taxes (varies by city/county)
- Franchise fees (payments to local governments)
- Regulatory fees
In Florida, the Gross Receipts Tax is a significant component. In the Carolinas, sales tax rates and local fees vary by jurisdiction.
