Zeo Energy & Creekstone Energy: Building a 10GW Data Centre

Something historic is taking shape in a quiet corner of Utah's Black Rock Desert. Millard County can be found on the westernmost edge of the Beehive State and consists of a flat, remote and sparsely populated area.

These attributes do not lend themselves well to most industries, but they are conducive to the construction of data centres.

Creekstone Energy is building what it calls a "gigasite" in Millard County. This project is a next-generation power and data infrastructure campus designed to feed the burgeoning electricity appetite of AI.

The site first broke ground in December 2025 and by the first half of 2027 Creekstone plans to have more than 300MW of gas-powered capacity online. That initial construction is reportedly only the beginning.

By the time the project is entirely finished it is expected to be the world's largest AI-optimised data centre campus boasting a power capacity of 10GW.

According to the Low Carbon Contracts Company, this would be enough electricity to power 15 million homes in Great Britain.

Zeo agrees energy partnership

On 18 February 2025 Creekstone announced it had signed a memorandum of understanding with Zeo Energy to develop around 280MW of solar and storage capacity for the site.

Zeo is a Florida-based clean energy company and for the firm this represents a pivotal moment in a transformation it has been undergoing for a while now.

When it acquired energy storage firm Heliogen in August 2024 Zeo set itself up to commercialise its offerings at a far larger scale.

With the data centre sector booming and demanding round-the-clock power it was unsurprising that Zeo got the call.

The kind of energy storage systems Zeo now has at its disposal are vital technologies in sectors such as data centres simply because they allow for the uninterrupted flow of renewable energy even when generation is intermittent.

Meeting urgent power demand

Ray Conley, CEO of Creekstone Energy, does not understate the scale of what is being asked of the energy sector right now.

"AI workloads are driving unprecedented demand for power," he explains.

"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 for the Gigasite is Blue Sky AI which has been allocated 50MW of energy. But the ambitions of Creekstone stretch well beyond that.

As things stand the firm is targeting multiple gigawatts of total capacity and clean energy solutions from Zeo are expected to form a key part of that picture going forwards.

Validating the storage model

Zeo has wasted little time in beginning work. Under the terms of the MOU the company has already begun a pre-feasibility study to determine the optimal solar and storage configuration for the site.

Its engineering team is drawing on the thermal and chemical storage know-how of Heliogen.

Tim Bridgewater, CEO of Zeo, is quite candid about what this project means for his company.

"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," says Tim.

"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 suggests that Zeo could provide engineering services for the project as well as potentially arranging financing for the project.

What is clear is that the tidal wave of demand for energy that AI has engendered is creating real opportunities for energy companies. Right now Zeo is positioning itself well to reap the rewards.
