Gulf Power customers will see slightly lower monthly bills because of lower fuel costs. Every year, the Florida Public Service Commission adjusts Gulf Power’s prices to reflect cost changes in fuel, environmental controls and energy conservation programs. Average residential customers will see their bills drop about $4.63. Gulf Power has also requested the Florida Public Service Commission approve a rate increase that would begin in July 2017. If approved, it would raise the average residential customer’s monthly bill by about $2.50 per month.
