How Zeo & Creekstone Will Power ‘Gigasite’ Utah Data Centre
In a remote corner of Utah’s Black Rock Desert, something historic is taking shape.
Millard County, at the western edge of the Beehive State, is flat, sparsely populated and isolated. These characteristics make it challenging for most industries but ideal for large-scale data centre construction.
Creekstone Energy is building what it has deemed a "gigasite" in the county – a next-generation campus that pairs data infrastructure with power generation to meet the soaring electricity needs of AI.
The site broke ground in December 2025 and Creekstone plans to have more than 300MW of gas-powered capacity online by the first half of 2027.
Completion of the campus will create the world’s largest AI-optimised data centre site, with a projected 10GW of capacity.
According to the Low Carbon Contracts Company, this is enough power to supply 15 million homes in Great Britain.
Solar and storage partnership
On 18 February, Creekstone signed a Memorandum of Understanding (MoU) with Zeo Energy, a Florida-based clean energy company, to deliver roughly 280MW of solar generation paired with storage systems at the site.
For Zeo, the deal is a major step in its ongoing transformation.
The company acquired energy storage firm Heliogen in August 2025, positioning itself to scale its offerings and bring long-duration storage solutions to large projects.
Constant power demands caused by data centres makes it a natural application for Zeo’s systems.
Meeting urgent AI demand
Ray Conley, CEO of Creekstone Energy, emphasises the pressure AI places on the energy sector.
"AI workloads are driving unprecedented demand for power," he says.
"At Creekstone, we plan to deliver over 600MW of baseload power to our Gigasite customers in 2027 in Phase 1 of our project.
"Our collaboration with Zeo reflects the market urgency of using all available energy sources to rapidly provide baseload power.
"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 centre customers."
The first confirmed tenant at the Gigasite is Blue Sky AI, which is allocated 50MW.
Creekstone targets multiple gigawatts of total capacity, with clean energy solutions forming a core part of future plans.
Validating the model
Zeo is wasting no time in preparing for the project. Under the MoU, it has begun a pre-feasibility study to determine the best configuration for solar and storage.
Zeo’s engineering team utilises Heliogen’s thermal and chemical storage expertise.
Tim Bridgewater, CEO of Zeo, explains: "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 centre space.
"Our MoU with Creekstone is a milestone in this effort and we are in discussions with several other projects that we believe can benefit from our clean baseload power solutions.
"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 centre customers in a cost-effective, low-emissions manner.
"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."
The MoU also indicates Zeo could provide engineering services and potentially arrange financing.
AI’s electricity demand is creating opportunities for energy companies.
Creekstone and Zeo have positioned themselves to meet this challenge, combining gas baseload with solar and long-duration storage at a 10GW scale in Millard County.
