Officials with E.On U.S. say the climate change bill passed by the U.S. House would translate into higher bills for LG&E and Kentucky Utilities customers, but not as high as originally predicted.

E.On U.S. is the parent of the two power companies. It had sent out mailings before the congressional vote that said bills could soar anywhere from 40 to 80 percent.

The legislation now moves to the U.S. Senate, which returns Monday with the goal of delivering a bill to President Barack Obama by the end of the year.
