Insights

Nuclear Energy Industry Expert

GSRT's Terra Innovatum secures first deployment site for SOLO reactor with potential for 50 MW commercial expansion, marking critical milestone toward commercialization.

Terra Innovatum has secured a significant foothold in the emerging micro-modular reactor (MMR) market through this strategic MOU with Rock City Admiral Parkway Development. The agreement establishes both a First-of-a-Kind (FOAK) deployment site for their 1 MWe SOLO™ reactor and includes an option for 50 additional reactors that could deliver up to 50 MWe of power capacity.

The site selection demonstrates pragmatic commercial thinking rather than purely academic research focus. Rock City's 6-million-square-foot industrial park provides an ideal testing ground with real-world power demands from industrial, logistics, food distribution, and government clients. This behind-the-meter deployment model addresses a critical market need for reliable, localized power that reduces dependency on grid infrastructure.

The 15-year initial term with extension options up to 45 years through core-swap lifecycle models represents a substantial potential revenue stream if regulatory approvals materialize. The Illinois location strategically positions Terra Innovatum within a nuclear-friendly ecosystem near Argonne National Laboratory and university research programs, potentially accelerating development through collaboration and talent acquisition.

What separates this from typical early-stage nuclear announcements is the focus on commercial application rather than just technology demonstration. The partnership represents the transition from theoretical design to practical deployment, though significant regulatory hurdles remain before operational reality. The NRC approval process for novel reactor designs is notoriously demanding, and commercialization timelines often extend well beyond initial projections.

• Partnership Agreement Provides Site for First-Of-A-Kind (FOAK) SOLO™ Nuclear Micro Modular Reactor (1 MWe)
• Agreement Includes Option to Purchase 50 SOLO™ Reactors to Meet Demand for Reliable Behind-the-Meter Energy Supplies (50 MWe)
• SOLO™ to Deliver Clean, Stable Energy Across Rock City’s Private and Public Sector Clients

AUSTIN, TX and NEW YORK, NY, July 09, 2025 (GLOBE NEWSWIRE) -- GSR III Acquisition Corp. (Nasdaq: GSRT), a publicly traded special purpose acquisition company, and Terra Innovatum Srl (“Terra Innovatum,” or the “Company”), a developer of micro-modular nuclear reactors, announced today that Terra Innovatum signed a Memorandum of Understanding (“MOU”) with Rock City Admiral Parkway Development (“Rock City”), a six-million square-foot industrial park in Illinois, to host the first deployment site for the SOLO™ micro-modular reactor. This strategic agreement grants Terra Innovatum dedicated use of Rock City’s land for the licensing, testing, and construction of the Company’s first-of-a-kind (“FOAK”) SOLO™ reactor. Subject to customary approvals, Terra Innovatum will supply Rock City’s industrial, logistics, food distribution and government clients with clean and reliable power from the FOAK SOLO™ with an option to subsequently deploy 50 reactors on site, delivering up to 50 MWe for commercial use.

In Picture: Rock City Admiral Park Development, a 6 million sq ft underground industrial park near St. Louis, offering secure, energy-efficient space for manufacturing, data centers, and logistics.

 “We are thrilled to partner with Rock City on the siting of our first SOLO™ reactor, which sets the critical foundation needed for the development and anticipated commercial operation of our innovative nuclear solution,” said Alessandro Petruzzi, Co-founder & CEO of Terra Innovatum. “Rock City is the perfect location for our first deployment as it showcases the massive real-world application potential of our micro-modular reactors and is in close proximity to a hotbed of nuclear research and talent. SOLO™’s modular design enables it to easily integrate into Rock City’s existing infrastructure, providing clean and reliable energy production at the point of demand without the need to connect to the grid.”

Joe Koppeis, Founder & Board Director of Admiral Parkway commented, “We are excited to partner with Terra Innovatum’s team to bring their innovative energy technology to the world. Once SOLO™ secures regulatory approval, we will be honored to host the FOAK and take the next steps towards wider commercialization.”

Gus Garcia, Co-CEO and Director of GSR III Acquisition Corp. said, “Today’s announcement is an important milestone for the regulatory and commercial advancement of SOLO™. Terra Innovatum’s site selection of Rock City demonstrates the strategic go-to-market design of SOLO™ – a reactor built for commercial scale, not just for research. We are excited to continue supporting the Company in its mission to deliver a truly differentiated and scalable energy solution to the world and are beyond proud to see them take their first steps to commercialization.”

Giordano Morichi, Partner, Chief Business Development Officer & Investor Relations of Terra Innovatum stated: “Rock City will put us at the center of Illinois’s vibrant nuclear ecosystem, which is home to the Argonne National Laboratory, the University of Illinois' nuclear programs, and a variety of U.S. Department of Energy-funded programs, providing opportunities for collaboration, funding, and talent sourcing. Additionally, the Midwest represents a key market for resilient and distributed power applications– offering significant local offtake potential. This partnership is not only a major step for our FOAK deployment, it tangibly propels the commercialization of our SOLO™ reactors for the need of the community and strategically positions Terra Innovatum for years to come.”

Pending NRC and other necessary approvals, the Company will supply power, with the potential for co-generation, to Rock City facilities under a 15-year term for the FOAK deployment, with the option to extend commercial operations up to 45 years through a core-swap lifecycle model, ensuring long-term energy continuity and infrastructure resilience.
