KANSAS CITY, Mo. (AP) — Kansas City Power & Light Co. says it will expand its use of wind energy and other energy-efficiency programs. The company announced Tuesday it will double its wind-generating capacity and open rebate programs to all Missouri customers. The Kansas City Star reports that KCP&L plans to buy 400 megawatts of power from two new wind turbine facilities, increasing its wind energy portfolio to 939 megawatts. The sites will be in Coffey County, Kansas and Holt County, Missouri. They are expected to produce power by early 2016. No rate increase is expected because of the expansion and KCP&L says it doesn't plan any increases in the next two years. The utility also says it wants to expand energy-efficiency programs that promote such things as improved lighting and recycling older appliances.
