TOPEKA, Kan. (AP) — Kansas regulators have delayed a vote on a Westar Energy proposal to raise its transmission charge for residential customers.

The Kansas Corporation Commission on Thursday pushed a final vote until March 31 on the Westar proposal to raise its transmission charge by 31 percent for home customers while cutting some business rates.

The Wichita Eagle reports commissioners said they have questions about the proposal, but didn’t say what those questions were in their meeting Thursday.

The proposed increase would bring Westar about $25 million more a year, in addition to the $78 million the company got in a general rate case in September.

The plan would raise the average home customer’s bill about $4 a month, while cutting the average small-business bill by about $31 a month.
