(JEFFERSON CITY, Mo., AP) — Missouri regulators have approved a request from Kansas City Power & Light-Greater Missouri Operations to raise the fuel charge on electric bills.

The Public Service Commission says the increase amounts to about 78 cents a month for residential customers in Kansas City, and $1.29 for those in St. Joseph. They take effect Sept. 1.

The fuel adjustment charge allows power companies to recover most of its fuel costs. Charges appear in a separate category on customer bills. The charge is designed to help utilities address volatility in fuel pricing.
