Wisconsin’s Lighthouse Project: OpenAI’s Bold Leap into Sustainable AI Infrastructure with Oracle and Vantage

Strategic Expansion of AI Infrastructure

In a significant move to bolster artificial intelligence capabilities, OpenAI is partnering with Oracle and Vantage Data Centers to establish a new Stargate data center cluster in Port Washington, Wisconsin. Dubbed ‘Lighthouse,’ this facility represents the fifth planned Stargate installation in the United States, joining previously announced locations in Texas and New Mexico. The project marks a strategic expansion of AI infrastructure beyond traditional technology hubs, positioning the upper Midwest as an emerging center for computational excellence.

Unprecedented Scale and Capacity

The Wisconsin campus is projected to reach nearly one gigawatt of capacity across four separate data centers, placing it among the most powerful computing facilities globally. Construction is scheduled to commence shortly with anticipated completion by 2028. This development is part of a broader national strategy that will see OpenAI’s Stargate network grow to approximately 4.5 gigawatts of total IT capacity across multiple locations.

Vantage Data Centers will develop 500 acres of the 672-acre site, with the remaining land dedicated to preserving natural biodiversity. The company has committed to planting over 2,000 native trees and creating extensive natural landscaping, including an eight-foot planted berm designed for sound mitigation using indigenous species., as related article

Sustainable Innovation and Environmental Stewardship

The Lighthouse project incorporates multiple sustainability initiatives that set new standards for data center environmental responsibility. The facility will utilize closed-loop liquid cooling systems and pursue water positivity through investments in local water restoration projects. Vantage has committed to deploying new solar, wind, and battery storage infrastructure, with approximately 70% of generated power allocated to the campus and 30% directed to Wisconsin energy customers.

WEC Energy Group anticipates the renewable energy deployment will eventually scale to nearly two gigawatts, though the initial phase may require supplemental power from conventional sources. The company has structured electricity rates specifically for this project to shield other customers from potential price increases resulting from the substantial infrastructure investments.

Economic Impact and Community Benefits

The development is expected to generate significant economic opportunities for the region, creating more than 4,000 skilled construction jobs, predominantly union positions, during the building phase. Once operational, the campus will support over 1,000 long-term employment opportunities.

Vantage has committed a minimum of $175 million to regional infrastructure improvements, including upgrades to water and wastewater treatment facilities, enhanced water mains and sewer lines, construction of a new water tower, and power infrastructure enhancements. These investments are designed to benefit both the data center operations and the surrounding community.

Industry Perspectives and Future Vision

Peter Hoeschele, OpenAI’s Vice President of Industrial Compute, emphasized the project’s broader significance: “Expanding Stargate to Wisconsin represents another major step toward building the infrastructure that will help ensure everyone can benefit from AI. This project will create good jobs, advance zero-emission energy, and boost the local economy—all while expanding capacity without raising rates for local consumers.”

Dana Adams, President of North America for Vantage Data Centers, highlighted the strategic importance of the location: “As demand for data centers expands beyond traditional hubs, the upper Midwest has become a critical and strategic market for Vantage Data Centers and our customers. Our investment in Wisconsin reflects the area’s strong foundation for digital growth to support sustainable AI innovation at scale.”

Broader Industry Context

The Lighthouse project arrives at a pivotal moment for the data center industry, as increasing AI computational demands drive unprecedented energy requirements. OpenAI’s multi-state Stargate initiative represents one of the most ambitious private infrastructure projects in recent memory, potentially reshaping regional economies and energy grids across the United States.

The Wisconsin facility’s approach to environmental responsibility, community engagement, and economic development may establish new benchmarks for how large-scale technology infrastructure projects balance operational requirements with community and environmental considerations.
