Google — Council Bluffs, Iowa AI Data Center Campus

Google's Council Bluffs, Iowa data center campus is one of the company's oldest and most significant US facilities, opened in 2007. The campus has undergone continuous expansion over nearly two decades and now represents a major component of Google's US Central AI training infrastructure. Located just across the Missouri River from Omaha, Nebraska, the Council Bluffs campus benefits from MidAmerican Energy's wind-heavy grid — one of the most renewable-intensive utility grids in the US.

The campus is documented as a key training location for Google's deep learning and AI workloads, including infrastructure that has supported the training of core Gemini model components. Iowa's low electricity rates from wind energy and Google's long-term power purchase agreements with MidAmerican wind farms have made the state the site of repeated Google capacity expansions.

Google has invested over $2 billion in the Council Bluffs campus across its expansion phases and has announced additional multi-billion-dollar investment tranches for 2024–2026. The facility includes multiple large data center buildings, high-voltage transmission interconnection, and dedicated fiber routes. Iowa and Nebraska together (per the Gemini cluster entry in this index) form one of Google's most powerful AI training concentrations globally.
