Building the infrastructure for the Intelligence Age in Michigan
Key Points
- 1 GW Saline campus (The Barn)
- Closed-loop cooling; no local ratepayer energy costs
- Up to $45M Codex credits + 2,500 union construction jobs
Summary
OpenAI and partners broke ground on The Barn, a 1 GW data center campus in Saline, Michigan, as part of the Stargate infrastructure program. The project emphasizes community-negotiated commitments: project-funded energy/infrastructure (no cost to local ratepayers), water protection via closed-loop cooling, union-first construction, local community investments, and AI training credits for students.
Key Points
- Scale & scope: 1 GW campus (The Barn) with partners Oracle, Related Digital, Walbridge, and Blackstone; part of OpenAI's Stargate program.
- Community protections: infrastructure and energy paid by the project — consumers will not see higher electricity bills tied to this build.
- Water & operations: closed-loop cooling system designed to use roughly the same water as a typical office building.
- Workforce & jobs: ~2,500 union construction jobs, ~450 permanent onsite roles, ~1,500 county-wide jobs, and ~1,000 indirect jobs; partnership with NABTU and state workforce programs.
- Community investment & finance: $10M toward Saline Recreation Center improvements; project projected to generate ~$1B in tax revenue over lease term.
- Skills & access: up to $45M in Codex credits available to >400,000 eligible Michigan college, community college, and trade-school students (2026–2027); AI literacy and workforce training in partnership with state agencies and community colleges.
Technical & engineering implications
- Infrastructure procurement and energy will be centralized under the project owner — expect on-site and utility interconnection coordination to be managed by the project team.
- Cooling design: closed-loop system minimizes potable water draw; plan for water monitoring and systems integration with building HVAC and power systems.
- Scale considerations: 1 GW of compute capacity requires coordinated electrical delivery, substations, distribution, and resilient networking; expect long-term capacity planning tied to Stargate.
- Labor and construction: unionized skilled-trades workforce and registered apprenticeship programs will be primary resources for site buildout, affecting scheduling and contractor selection.
Actionable notes for engineers
- Coordinate with project owners on interconnection, substations, and meter arrangements to confirm that local ratepayers are not exposed to incremental costs.
- Review closed-loop cooling specs and monitoring requirements early to align MEP and water-usage reporting.
- Engage workforce-development partners for apprenticeship pipelines and verify credentialing expectations for onsite hires.
