Average Utility Costs in Wilmington, NC

Estimated monthly utility costs (1,000 kWh + 5,000 gal)

Average monthly utility costs in Wilmington, NC are about $274.98, based on 1,000 kWh of electricity and 5,000 gallons of water. This estimate uses Duke Energy Progress for electric service and layers in the local water, wastewater, and solid waste charges that residents actually budget around.

Wilmington quick take

  • Electric service is benchmarked from Duke Energy Progress, which fits North Carolina's regulated utility structure rather than a retail electricity shopping market.
  • Wilmington relies on a regional water or wastewater authority, so the non-electric part of the bill reflects more than just a city utility department.
  • Trash is shown as a clearly labeled baseline estimate where the public service pages are easier to confirm than a simple posted monthly fee table.
  • Across North Carolina, local water, wastewater, and trash policies can change the full household bill more than many residents expect.

FAQ

This page uses the local regulated-utility benchmark so readers can compare Wilmington with other North Carolina cities on the same 1,000 kWh basis. Your actual bill can still vary with season, riders, usage pattern, and the specific utility territory tied to your address.
Because household utility costs are not just about electricity. In North Carolina, city or regional water, wastewater, and solid waste charges can add a meaningful fixed monthly cost, so the full utility bill is often more useful than the electric number alone.
Trash in Wilmington is provided by the city as part of municipal utilities and is billed at a monthly fee. Rates and services are set by the local government; our estimate uses the fee from City of Wilmington – Recycling and Trash Services FAQ.
We use base charges and per-unit rates from official provider pages. Electric = base + (rate × assumed kWh). Water = base + (rate per 1,000 gal × assumed gallons / 1,000). Sewer is either a flat fee or a percentage of water. Trash is a fixed monthly fee. See the Methodology page for full formulas.
Actual bills depend on your usage, seasonal rates, taxes, fees, and provider-specific rules. Our estimates use fixed assumed usage (e.g., 1,000 kWh, 5,000 gal) for comparison. Your home may use more or less.
Each component shows a 'last verified' date. We aim to update from official sources periodically; always confirm current rates on the provider's site before making decisions.
