In 2006 Microsoft constructed the first phase (470,000 square feet) of the ‘Columbia Data Center’ in Quincy, Washington
Microsoft decided to build in Quincy because of the city's commitment to build fiber and extremely low cost electricity provided by Grant County PUD for as little as 1.9 or 2.5 cents per kilowatt-hour. In 2006 Microsoft built a 500,000-square-foot facility and several expansions followed with a total 800,000 square feet of floors pace in two buildings on a 270-acre campus.
In 2021 Brad Smith gives a video tour of Microsoft's Columbia (Quincy) campus. https://youtu.be/80aK2_iwMOs
