(Richmond, IN)--February 18 has been set as the date that Richmond Common Council will first take public comment on a potential Richmond Power & Light rate increase. The proposed increase would increase RP&L’s revenue by close to ten percent and would help the utility to fund a multi-million-dollar mandate to clean up coal ash. "Rough estimates that we've got at this point go as low as $18 million and as high as $55 million," said RP&L General Manager Randy Baker. An average homeowner would see his monthly bill increase by about ten dollars. If a rate increase is approved by council, it would then have to be approved by the Indiana Utility Regulatory Commission.
