US-based solar and storage company Zeo Energy has announced that it has signed an agreement with Creekstone Energy to develop approximately 280 MW of baseload power for a new AI-focused data center campus in Millard County, Utah, approximately 175 miles southwest of Salt Lake City.
Zeo Energy said the MoU will enable behind-the-meter solar in combination with LDES to be supplied to Creekstone’s ‘Gigasite’, a multi-source power and data hub serving a new network. AI-focused data center campus.
Creekstone began construction in December 2025 and plans to deliver more than 300 MW of gas-based power to data center customers at the Gigasite by mid-2027, including an announced “up to” 50 MW for Blue Sky AI, a previous agreement signed in August 2025.

The event will spotlight how solar and energy storage solutions are powering sustainable and reliable infrastructure, with a particular focus on powering the country’s fast-growing data center sector.
Further plans from Creekstone will see energy production increased to several gigawatts, integrating clean energy sources such as Zeo’s solar-plus-storage systems.
Under the MoU, Zeo Energy said it has initiated a pre-feasibility study to determine the most efficient solar generation combined with long-term thermal and chemical storage for the Gigasite. The agreement also outlines potential roles for Zeo in project financing, engineering services and front-end design work.
The MoU announcement does not provide details on the exact type of storage to be considered part of the MoU, although it is repeatedly referred to as ‘long term’.
Guiding the future, Zeo Energy acquired concentrated solar power tower specialist (CSP) Heliogen in August 2025, which can serve to combine solar PV with solar CSP to provide 24-hour power to the data center sector.
“Since our acquisition of Heliogen, we have been actively seeking to apply our long-term storage expertise to the unprecedented power demands in the data center space,” said Tim Bridgewater, CEO of Zeo Energy. “Our MoU with Creekstone is a milestone in this effort, and we are in discussions with several other projects that we believe could benefit from our clean baseload energy solutions.”
Zeo Energy is already working on several other projects that are also in the planning and evaluation phase. The caption on the company’s provided photo read, “Solar array nearby in Millard County, Utah, similar to the type being considered for the Gigasite,” as a clue.
“At Creekstone, we plan to deliver more than 600 MW of baseload power to our Gigasite customers in Phase 1 of our project by 2027. Our partnership with Zeo reflects the market’s urgency to use all available energy sources to quickly deliver baseload power,” added Ray Conley, CEO of Creekstone Energy, noting the urgency of power supply for data centers. “With solar and Zeo’s sustainable energy storage solution, we plan to significantly expand the amount of clean energy we provide to our hyperscaler and artificial intelligence data center customers.”
