The state’s utility regulator this week will decide part of Duke Energy Florida and Tampa Electric Co. customers’ bills for 2019. In what is scheduled as a three-day hearing beginning at 1:30 p.m. today, the Florida Public Service Commission will vote on proposals to recover costs from customers for fuel, energy conservation, purchased gas, natural gas and environment. The annual hearings determine the rates paid by customers of the state’s investor-owned utilities. Fuel is considered a "pass-through" cost, meaning the utilities do not make money off of it.Check back here for updates.MORE: Get more business news here Contact Malena Carollo at [email protected] or (727) 892-2249.
