YUMA, Ariz.- This holiday season Arizona Public Service customers will be having a break on their bill. Residential customers can expect up to 3% credit on their next bill. Commercial customers can expect even a higher credit giveback with up to 6.3%. The main reason behind the giveback is to do the overall lower cost of fuel. The credit will start on the November bill cycle and will extend to January afterwards the costs will be reevaluated.
