By Mike Genet mike.genet@examiner.net The Examiner While state and federal agencies look into the energy prices during February’s cold snap, some Independence City Council members warn about sticker shock if the city’s electric utility has to recover some costs. The municipal utility had told customers a few weeks ago that they would see slightly higher bills into the summer due to the cold snap. To recover some of those costs, IPL said customers would see an increase of about $9 to $10 in the fuel-cost-adjustment portion of their bill for several months. Department director Jim Nail said he chose that method rather than a single, higher add-on to bills.
