Google Council Bluffs Data Center

The story

Google broke ground in Council Bluffs, Iowa in 2007, drawn by abundant Midwest wind power, low seismic risk, and vast industrial acreage along the Missouri River. Over nearly two decades and more than $5 billion in capital investment, the site expanded into one of the largest data processing and AI training complexes in the world. Council Bluffs houses thousands of Google's custom Tensor Processing Units (TPUs) interconnected on optical circuit switches, providing the supercomputing muscle that trained Google's flagship Gemini multimodal foundation models.

Notable

• Google has invested over $5 billion in its Council Bluffs campus since breaking ground in 2007.
• Hosts massive TPU (Tensor Processing Unit) clusters that trained Google's flagship Gemini models.
• Operates with a trailing-twelve-month PUE of approximately 1.10 across multiple interconnected campuses.
• Matched by hundreds of megawatts of long-term wind power purchase agreements on the MidAmerican Energy grid.
