US-based Creekstone Energy has signed a Memorandum of Understanding (MOU) with EnergySolutions to evaluate potential nuclear power options for the Utah Creekstone Gigasite and possibly additional locations. The strategic agreement outlines a structured process to study the feasibility of integrating at least 2 GWe of next-generation nuclear capacity considering multiple nuclear technologies, which include large-scale and small modular reactors (SMRs), of different designs.
Creekstone aims to provide approximately 10 GWe of non-nuclear generation at the Gigasite through a diversified portfolio of power and infrastructure technologies possibly including next-generation nuclear capacity.
Creekstone CEO Ray Conley said evaluating the role next-generation nuclear could play in the broader energy portfolio is an important step in refining the long-term strategy for the Gigasite. “Nuclear has the potential to complement our multi-source approach and support the growth of large-scale AI and digital-infrastructure development. EnergySolutions’ technical and regulatory expertise gives us confidence that this evaluation will be thorough, professional, and grounded in real-world conditions.”
“Creekstone is approaching this the right way, grounding every step in thorough analysis, clear options, and a disciplined process,” said Pierre Oneid, Executive Vice President for strategic initiatives & partnerships at EnergySolutions. “Our role is to help them fully understand the nuclear pathways available and what it would take to make any of those options viable for a site of this scale.”
The MOU is non-binding and establishes a framework for structured evaluation without obligating either party to pursue a specific project, technology, or investment. It envisages a Phase 1 evaluation effort focused on:
- Developing a nuclear programme roadmap, with timelines and gating decisions tied to feasibility, regulatory progress, and commercial conditions.
- Establishing a timeline for commercial operation in the 2030–2035 timeframe.
- Assessing a wide range of reactor technologies, without limitation to any single design, to determine which options may merit further study for Gigasite-scale loads.
- Evaluating site readiness and integration requirements within Creekstone’s multi-source energy strategy, including transmission, cooling, and infrastructure interfaces.
- Examining regulatory pathways and early-stage licensing considerations to understand requirements for any future project.
- Identifying commercial structures, delivery models, and key risks to inform next steps.
The Creekstone Gigasite is a next-generation, multi-source power and digital-infrastructure campus in Delta, Utah. It is designed to support the unprecedented energy and cooling demands of large-scale AI compute and integrates utility-scale generation, long-duration storage, advanced transmission, and industrial-grade data infrastructure.
Creekstone’s current plan includes a diversified portfolio of non-nuclear energy resources. The evaluation of nuclear energy introduces an additional potential pathway to strengthen long-term reliability, resilience, and capacity. Nuclear is being studied as a possible complement to the broader strategy, not a replacement for other technologies. Because nuclear development involves long regulatory and planning timelines, early evaluation is deemed critical to understanding which options, if any, may be viable for the Gigasite.
Creekstone and EnergySolutions will evaluate all viable nuclear technologies, including large reactors, small modular reactors, and advanced designs, doing so without predetermining any preferred option. Final recommendations will be based on safety, feasibility, regulatory readiness, commercial conditions, and applicability to Gigasite-scale loads. If pursued, initial commercial operation would likely fall in the 2030-2035 timeframe, consistent with typical regulatory, licensing, and construction timelines for new nuclear development.
