Fermi begins nuclear reactor production for data centers (US)

The US-based energy grid developer Fermi has signed agreements to begin production of four large nuclear-power reactors that will supply energy to a private data center grid campus in Texas (United States). The first contract, signed with South Korean company Doosan Enerbility, includes the manufacture of reactor pressure vessels, steam generators, and other critical components. “This strategic deal locks in Fermi’s preeminent position for Westinghouse AP1000 reactor projects” (Fermi press release, 27/10/2025).

The US company has also signed a separate contract with Hyundai Engineering & Construction (E&C). According to its press release, the Front-End Engineering Design (FEED) contract with Hyundai E&C will initiate engineering activities for Project Matador, a private grid campus currently under construction in Texas.

The campus is designed to combine natural gas, solar, nuclear, and battery power for a total capacity of 11 GW.

This announcement follows a Memorandum of Understanding (MoU) signed in summer 2025 with Doosan for the development of large-scale commercial nuclear plants and small modular reactor (SMR) technologies, as well as a Strategic Partnership Agreement with Hyundai E&C, marking the Early Contractor Involvement (ECI) phase of their long-term partnership.

A full Engineering, Procurement, and Construction (EPC) contract is expected to be finalized in early 2026.
