ONE Nuclear Energy

What ONE Nuclear Energy does

ONE Nuclear Energy LLC is an independent US developer, owner, and operator of GW-scale power generation infrastructure, headquartered in Florida and founded in 2025. The company targets data centers, industrial facilities, and utilities in Texas and the Southwest US, where accelerating electricity demand from AI computing and industrial growth is outpacing grid interconnection timelines. Its integrated develop-own-operate model combines fast-track natural gas reciprocating power units with long-dated advanced nuclear small modular reactor (SMR) capacity, supplemented by behind-the-meter microgrid solutions that can operate islanded from the grid to bypass multi-year interconnection queues.

The company's core technology stack pairs modular, factory-fabricated natural gas generation — chosen for shorter delivery lead times than turbines — with SMR designs from multiple technology vendors, including Rolls-Royce SMR, evaluated for low technology and execution risk. EPC execution is supported by Futureworx and Black & Veatch, and a strategic relationship with one of the top five US energy traders optimizes PPA structuring, market access, and risk management. A portfolio of 75+ identified sites underpins a stated path to 15 GW of hybrid gas and nuclear projects by 2033, with three active development sites in East Texas, New Mexico, and Washington, an 18,275-acre West Texas portfolio under LOI with Sunshine Partners, and first projected revenue from the East Texas gas site in 2028.

Commercially, ONE Nuclear sells electricity via long-term power purchase agreements and direct power sales to enterprise customers, with managed behind-the-meter services as a complementary offering. The company is currently private and pursuing a public listing through a SPAC business combination with Hennessy Capital Investment Corp. VII (HVII), valued at approximately $1 billion with up to $210 million in expected gross proceeds, targeted to close in the first half of 2026 and list on Nasdaq under the ticker ONEN.

Core offering

ONE Nuclear Energy develops, owns, and operates GW-scale power generation infrastructure combining fast-track natural gas reciprocating units with advanced nuclear Small Modular Reactor (SMR) technology, supported by behind-the-meter microgrid capabilities. The company sells electricity and capacity directly to data centers, industrial customers, and utilities through long-term Power Purchase Agreements (PPAs). Its integrated develop-own-operate platform spans 75+ identified sites with three active development projects in East Texas, New Mexico, and Washington, targeting up to 15 GW of hybrid nuclear and gas projects by 2033.

Product overview

ONE Nuclear Energy offers an integrated develop-own-operate platform for GW-scale power infrastructure combining two core products: fast-track natural gas power generation using reciprocating units for immediate deployment, and advanced nuclear SMR power infrastructure for long-term clean energy. Their offering includes behind-the-meter microgrid solutions as an add-on capability. The platform supports multi-technology strategies, selecting the right technology for specific customer and site requirements, with a portfolio approach spanning 75+ potential locations and current development sites in East Texas, New Mexico, and Washington.
