Monthly rates will go up $4.93 a month next year for a typical Progress Energy Florida customer due to a settlement that has received state approval. The Public Service Commission on Wednesday endorsed the deal Florida's second-largest electric utility reached with consumer advocates last month. It includes a $288 million refund of costs resulting from the shuthdown of a nuclear plant at Crystal River but base rates go up $150 million. That's a net increase of $4.93 a month for a customer using 1,000 kilowatt hours, which is about average, for a total of $128.12. The utility has 1.6 million customers, including 60 thousand in Marion County. The nuclear plant will be temporarily removed from the base rate. The pass-on of costs associated with a proposed nuclear plant in Levy county also will be limited. The company serves central and north Florida.
