Topeka - State utility regulators declared prudent Westar Energy Inc.'s proposal to produce nearly 300 megawatts of wind power.
But the Kansas Corporation Commission declined to approve an additional one percent bonus that was requested by Westar.
Westar had sought pre-approval to increase rates on the average customer by $2.25 per month. Without the additional one percent rate of return, it was unclear how much the proposed monthly increase would be.
Included in its proposal, Westar planned to build 149 megawatts of wind generation and purchase from other companies 146 megawatts.
Westar officials said they would comment Friday after reviewing the KCC decision.
