Beginning in April, Duke Energy's name will replace Progress Energy Florida on monthly bills and signs around Central Florida.
The utility has been publicizing the name change in recent days in mailings to customers. The company plans to phase in the name change through the spring and summer and expects to complete the switch in July.
"We are notifying customers now of the upcoming name change so there is no confusion around the company name on future bills," said Sterling Ivey, a company spokesman.
Progress Energy merged with Duke Energy last July to form the largest utility in the United States. Progress Energy Florida became part of Duke Energy but kept its name — until now.
Duke Energy now provides power to 7.1 million customers in six states: Florida, North Carolina, South Carolina, Kentucky, Ohio and Indiana.
The company's new signature image will reflect the star from Progress' logo and the swoosh from Duke's.
The company said the sky blue, navy and green in the design express the utility's commitment to "sustainability, technology and energy efficiency."
Duke will maintain its principal headquarters in Charlotte, N.C. The company plans to keep its Florida headquarters in St. Petersburg.
No specific day has been set for the changing of the name on the Progress Energy building in St. Petersburg.
