There's no doubt that Kentucky's electricity bills are on the rise, as utilities sort out how much it will cost them to comply with new federal environmental regulations. Kentucky Utilities, the largest electricity provider in Central Kentucky, has asked the state Public Service Commission for permission to increase the average customer's monthly bill more than 12 percent by 2016. But this case is far different than those that are familiar to most people. It's not about base rates, which look at the price for a kilowatt hour of electricity. It's about the environmental surcharge you find on your bills.
