Due to the rise of cloud computing, big data, and mobile internet, data centers will continue to maintain a strong development trend in the coming years. Internet giants are pouring huge investments into this sector. Not long ago, Google announced a $300 million investment to expand its data center in Belgium. According to The Des Moines Register, Facebook may have an even bigger move, investing over $1 billion in Altoona, located in the central United States, to build one of the world's most advanced data centers.Facebook already has three data centers located in Prineville, Oregon; Forest City, North Carolina; and Luleå, Sweden. Among these, the largest is in Prineville, covering 130,000 square meters. It is reported that the new project will span 809,000 square meters, equivalent to 113 football fields. Construction will be carried out in two phases, with Facebook investing $500 million per phase, bringing the total cost of the project to an estimated $1.5 billion. Connections between Facebook and this project stem from a tax incentive application related to wind power generation tied to the project. However, all parties involved declined to comment on the matter.Facebook has been promoting the Open Compute Project, hoping to share its experience in building data centers with others. Its data center in Prineville achieved a stunning PUE (Power Usage Effectiveness) value of 1.07, significantly lower than the industry average of 1.5 (China’s average is 2.2-3).Due to relatively low hydroelectricity costs, Iowa, where Altoona is located, is home to multiple data centers. Google has invested $1.1 billion in constructing a data center in Council Bluffs, while Microsoft's data center in West Des Moines cost at least $100 million. Facebook's planned data center in Altoona is transforming the area into a U.S. data center corridor, alongside LightEdge and Enseva, whose data center is set to break ground this spring.Abundant fiber-optic resources, rich hydroelectric resources, low land prices, low natural disaster risks, and convenient transportation are among Altoona's advantages. Similarly, China's three major telecom operators have made substantial investments in Inner Mongolia for cloud computing data centers, likely considering similar factors.
