The company seeks an overall annual increase in its Kansas operating revenue of about $1.5m, or about 6.39%.

If approved, a Kansas residential customer using 1,000kWh of electricity will experience a monthly increase of about $7.

According to the company, any new rates approved would not become effective for the Kansas customers until late 2011 or early 2012.

Empire District Electric president and CEO Brad Beecher said the company seeks new Kansas rates to finish the recovery of costs associated with new generating units, Iatan 2 and Plum Point, plus the annual operating costs associated with these new units.
