The project, which is located in Beaver County, consists of 60 Vestas V117-3.3MW turbines.

It is expected to generate 845,000 megawatt hours of electricity a year.

RES developed the project and also served as the engineering, procurement and construction contractor.

Google signed a power purchase agreement for electricity from Bluestem in December 2015, RES said.

Almost 500 workers were employed during construction, with a peak daily workforce of over 200 people at the height of construction, the company added.
