The Kansas Corporation Commission was meeting Thursday to discuss KCP&L’s rates for its 247,000 customers in the state’s northeast corner. It was the last day the commission could issue a rate-setting order under state law.

KCP&L proposed boosting its annual revenues by $67 million and estimated its request would raise rates by 12.5 percent or $11.67 a month for an average residential customer.

But a state consumer advocacy agency says decisions already announced publicly by the commission suggest KCP&L’s rates will increase about $40 million annually.

The company contends it needs additional revenues to pay for power plant upgrades.
