Kansas City Power & Light is planning to take on energy from two wind farms in northwest Missouri.

KCP&L made the announcement Thursday of the purchase of an additional 500 megawatts (MW) of power from two new wind facilities in its service region. That’s enough energy to power up to 170,000 homes.

One wind farm is in Osborn in DeKalb County and a second in Rock Creek in Atchison County.

“This announcement marks a significant investment in renewable energy, and will benefit our customers and the region,” said KCP&L President and CEO, Terry Bassham. “Over the past decade, we’ve transitioned our energy mix to become more sustainable and cleaner, and today is the most recent in a series of investments in renewable energy. We’re excited to announce our first wind facilities in our Missouri service area.”

Osborn is a 200 MW wind farm that is being constructed by NextEra Energy Resources in DeKalb County just east of St. Joseph, Mo. Osborn is expected to reach commercial operation by the end of 2016.

Rock Creek is a 300 MW wind farm that is being constructed by Tradewind Energy in Atchison County, near Tarkio, Mo. Rock Creek is expected to reach commercial operation by September, 2017.
