Bills for residential customers of Duke Energy Progress, which serves Eastern North Carolina and the Asheville area, went up 4 percent this week.
The increase comes from five billing adjustments the North Carolina Utilities Commission approved, effective Monday. Those adjustments included changes to fuel costs, energy efficiency and renewable energy programs.
Residential customers who use 1,000 kilowatt-hours of electricity a month will pay an extra $4.80 a month, increasing the average bill from $106.67 to $111.47.
Duke Progress serves 1.3 million North Carolina customers.
