The increase includes annual changes in the power company's costs of fuel and purchasing renewable energy. This year also includes costs from buying out several municipalities for their share of Duke Energy nuclear plants. Customers also got a savings because the company saw a federal income tax cut this year.

The increase comes on top of $7.63 per month the average household began paying in March for power system upgrades, coal ash cleanup and other costs.
