## Reviewed overview

Bluestem Wind Project is a 198 MW wind farm in Beaver County, Oklahoma, made up of 60 Vestas V117-3.3 MW turbines that entered commercial operation in October 2016. Renewable Energy Systems developed and built it before Exelon Generation, now Constellation, bought it in December 2015. Power moves over OG&E's transmission system into the Southwest Power Pool, and Google has a 15-year agreement to buy the output.
