Citizens' Utility Ratepayer Board

Westar Energy is asking to raise the rates on residential and small business customers and lower the rates for large businesses.

Homeowners or small businesses would pay 6 to 9 percent more under Westar Energy's latest plan. Big businesses that buy lots of power would pay 6 to 15 percent less.

Westar officials say industrial users and other large-volume customers are paying more than their share.
