PRINEVILLE, OR -- Facebook is growing again, in Prineville. The social media giant announced Thursday it will construct two more buildings, bringing its total footprint to 3.2 million square feet, in Crook County. Its last expansion was announced last December.

Facebook officials estimate the additions to its data center campus near the Prineville Airport will bring 100 additional jobs, taking the company's local workforce to 450. Crook County Judge Seth Crawford says it's a huge benefit to the economy, "With this increased construction and building new facilities here, we’re seeing those families move back." Crook County Schools Superintendent Dr. Sara Johnson says Facebook is a major supporter, "The contributions that you’re making to our school district are giving the people who are serving kids the power to build this community." She adds, "I was able to count up 397,162 that Facebook has contributed to the School district."

Construction is expected to cost $750 million, and should be complete by mid-2020. In July, Facebook announced a major solar power initiative for its existing facilities, and increasing the amount of solar power in Oregon by more than 20%. They anticipate the new data centers will also be "hyper-efficient" and be supported by the new renewable energy resources under development in the area.
