Private developer outlines 11,000‑acre ‘Valley Forge’ energy city with generation, storage and transmission plans

SALT LAKE CITY — Representatives of Invictus Sovereign presented a large‑scale proposal to the Public Utilities, Energy and Technology Committee for ‘‘Valley Forge,’’ a master‑planned energy community in central Utah that the company said would combine power generation, long‑duration storage, transmission and advanced manufacturing over roughly 11,000 acres.

Wayne Aston, chief executive of Invictus Sovereign, described the project footprint and economic rationale and said the SentinelOne power complex will include combined‑cycle gas, steam turbines and reciprocating engines that are ‘‘all of them hydrogen capable in the future.’’ Aston said the company has executed an order with Westinghouse for a 2‑gigawatt long‑duration energy storage system and that the company is in commercial discussions with Westinghouse on deploying additional nuclear technology, including AP1000 reactors and smaller modular units as they become licensed.

Why it matters: Invictus described the project as aiming to supply multi‑gigawatt capacity to meet fast‑growing demand from data centers and other large users while supporting local housing, agricultural modernization and manufacturing. The proposal also includes a proposed 765‑kilovolt transmission backbone the developer says would harden and expand the corridor to support higher loads and create redundancy with the Intermountain Power Plant.

Aston said the company has assembled roughly 11,000 acres about 10 miles south of Fillmore with dark fiber along the I‑15 corridor and dual 36‑inch natural gas transmission line frontage. He outlined a water‑management plan that the company said could include aquifer reinjection, water reclamation and harvesting and that — under the firm’s modeling — could produce a multi‑year aquifer surplus within about 13–14 years through conservation and recharge measures. Aston said the site sits in Air Shed Zone 2 and that Westinghouse is developing a more water‑efficient AP1000 design that could reduce cooling water needs.

Aston described Westinghouse’s pumped‑thermal (solid‑state) storage technology as able to provide ‘‘200 to 300 hours’’ of storage on large deployments and said Westinghouse is contracted for a 2‑gigawatt, long‑duration system for Valley Forge. He also described existing Memoranda of Understanding with small modular reactor developers and said Invictus expects potential manufacturing and fuels fabrication roles on site if advanced nuclear is permitted and financed.

On transmission, Invictus said it has Quanta Services under consideration as the engineering, procurement and construction contractor for a proposed 765 kV line connecting Valley Forge with the Mona Clover station and potentially looping to the Intermountain Power Plant to create redundancy and resilience. Aston said the company is pursuing right‑of‑way strategies that leverage existing corridors and federal categorical exclusions where appropriate.

Committee members asked about aquifer monitoring, traffic and construction impacts, timeline and pushback. Aston said the project would phase in over decades, that the company has spent more than $12 million assembling land to date, and that the developer has discussed the proposal with Millard County commissioners and local officials. He said construction would generate notable truck traffic during build‑out and that the company plans localized batch plants and an I‑15 interchange to manage flows.

Invictus representatives and committee members repeatedly characterized Valley Forge as complementary rather than competitive with the Intermountain Power Plant, noting hydrogen storage infrastructure and pipeline access as potential points of coordination.

The presentation was informational; no committee action was taken. Members thanked the presenters and invited follow‑up briefings on technical, water and transmission details.
