In the remote Black Rock Desert of Utah, a groundbreaking project is underway that aims to redefine the energy landscape for artificial intelligence (AI) operations. Creekstone Energy has started construction on a next-generation "gigasite" in Millard County, which will house the world’s largest AI-optimized data center. With a projected capacity of 10GW, the site will integrate advanced data infrastructure with diverse energy sources to meet the surging electricity demands driven by AI technologies.
The Millard County location, characterized by its isolation and sparse population, offers ideal conditions for large-scale data center development. Creekstone Energy's ambitious project broke ground in December 2025, and the company plans to bring over 300MW of gas-powered capacity online by the first half of 2027. Once complete, the gigasite is expected to generate enough power to meet the electricity needs of 15 million homes in Great Britain, as per estimates from the Low Carbon Contracts Company.
Ray Conley, CEO of Creekstone Energy, highlighted the urgency of addressing the immense power demands of AI. "AI workloads are driving unprecedented demand for power", Conley said. "At Creekstone, we plan to deliver over 600MW of baseload power to our Gigasite customers in 2027 in Phase 1 of our project."
On February 18, Creekstone announced a Memorandum of Understanding (MoU) with Florida-based clean energy company Zeo Energy to bolster the project’s renewable energy capacity. Through this deal, Zeo Energy will deliver approximately 280MW of solar power paired with energy storage systems to the site. This integration of solar energy and long-duration storage solutions marks a major step toward providing a cleaner power mix for the data center’s energy-intensive operations.
"Our collaboration with Zeo reflects the market urgency of using all available energy sources to rapidly provide baseload power", Conley said. "With solar power and Zeo's long-duration energy storage solution, we plan to significantly expand the amount of clean power we offer our hyperscalers and artificial intelligence data center customers."
Zeo Energy has positioned itself as a leader in clean energy solutions following its acquisition of energy storage firm Heliogen in August 2025. By leveraging Heliogen’s thermal and chemical energy storage technologies, Zeo aims to address the constant power demands of AI-focused data centers. Zeo has already begun a pre-feasibility study under the MoU to determine the optimal configuration of solar and storage systems for the Creekstone gigasite.
Tim Bridgewater, CEO of Zeo, elaborated on the significance of the partnership. "Since our acquisition of Heliogen, we have been actively seeking to apply our long-duration storage expertise to the unprecedented power demand in the data center space. Our MoU with Creekstone is a milestone in this effort", Bridgewater said. "The Creekstone collaboration is an opportunity to validate the application of our expertise in renewable power generation and long-duration storage to increase power delivery for data center customers in a cost-effective, low-emissions manner."
The Creekstone gigasite has already drawn its first confirmed tenant, Blue Sky AI, which has been allocated 50MW of capacity. Creekstone Energy envisions the site expanding to multiple gigawatts of total capacity as it continues to incorporate clean energy solutions into its infrastructure.
Bridgewater emphasized Zeo’s broader goals, stating, "We are in discussions with several other projects that we believe can benefit from our clean baseload power solutions. We expect our ability to access the public capital markets to provide project financing could give us a competitive edge in our business development efforts."
By combining gas baseload power with solar energy and long-duration storage systems, Creekstone Energy and Zeo Energy are poised to address the unique energy challenges presented by AI. This innovative approach not only supports the energy-intensive data center industry but also sets a new benchmark for integrating renewable energy into large-scale infrastructure projects.
