State regulators signed off on two settlement agreements that include Duke Energy Florida and Tampa Electric Co. using money from federal tax savings to cover the costs of restoring power after Hurricane Irma and other major storms.

The settlements, which combine to total $575 million, were reached after negotiations between the utilities, the state Office of Public Counsel, the Florida Retail Federation and the Florida Industrial Power Users Group. The Office of Public Counsel represents consumers in utility issues, while the business groups represent major commercial electricity users.
