Fusion energy is entering a new era, driven by scientific progress and the ability to deliver projects that utilities can permit, build and operate.
We are advancing this shift with fusion energy technology developer Type One Energy and the leading United States (U.S.) power utility, Tennessee Valley Authority (TVA), through conceptual design work for Infinity Two — a first-of-a-kind (FOAK) stellarator fusion power plant intended to supply a minimum of 350 megawatts of secure, reliable and clean electrical energy, enough to power approximately 250,000 homes. As conceptual design engineering partners, we help translate fusion ambition into practical, site-ready infrastructure, reducing risks on the path from concept to delivery and supporting the long-term transition to more resilient energy systems.
Infinity Two reflects a growing approach to fusion development that links private‑sector innovation with utility governance and state regulatory support. The project brings together Type One Energy’s stellarator technology, TVA’s delivery experience in Tennessee, U.S., and the state’s proactive regulatory environment for advanced energy projects. In partnership with these organizations, our teams are working to convert fusion concepts into actionable plans that align technical requirements with real-world constraints and regulatory compliance.
Through this model, we help partners move through the critical early development stages that determine how a fusion project can progress into a buildable and financeable clean‑energy asset. Fusion projects worldwide face significant early‑stage challenges — from regulatory complexity to new delivery models and stakeholder coordination — and our work on Infinity Two is designed to help address these barriers through clear, practical engineering and transparent development pathways in pursuit of a more sustainable global energy future.
Advancing FOAK fusion through coordinated development
Early decisions around siting, permitting, licensing, governance and integration are critical to the viability of any energy project, and fusion adds the complexity of fitting a new technology into existing regulatory frameworks. For Infinity Two, we’re working with Type One Energy and TVA to help navigate and shape these early activities, including planning related to the former Bull Run site and aligning the technical concept with site‑specific characteristics and state and federal requirements. Collaboration and information sharing with the state of Tennessee has played a key role in sustaining progress and helping the program progress through these complex stages. Together, our collaboration supports the development steps that shape success before construction begins, helping accelerate progress, reduce early risk and build delivery models that can scale globally.

Translating fusion ambition into site-ready infrastructure
As conceptual design engineering partners with a deep understanding of supply chain systems, our experienced teams prioritize operations and maintenance considerations, cost efficiencies and speed-to-market across programs. With local knowledge backed by global expertise, we are helping take Infinity Two from theoretical design to engineering and development plans that reflect real-world conditions, regulatory expectations and utility requirements.
Our work supports:
- Site selection and environmental assessments, including evaluation of potential locations, impact modeling and permitting strategies that anticipate regulatory hurdles.
- Systems integration and interface management, designing and engineering solutions that integrate civil, mechanical, electrical and control systems to maximize efficiency and affordability, unifying power plants under a common goal, timeline and budget.
- Project controls and risk management, providing schedule controls and risk registers that support decision-making and transparency as requirements evolve.
- FOAK licensing and compliance, supporting safety cases, compliance documentation and licensing submissions for first-in-kind technology.
This approach reduces early uncertainty, clarifies sequencing and requirements, and helps regulators, utilities, investors and communities understand how the project will progress.
Building on established progress in fusion engineering
Type One Energy’s ongoing technology development provides the technical basis for the program. Our teams are supporting Infinity One and Infinity Two concurrently, enabling insights from ongoing prototype‑scale engineering to directly inform conceptual decisions for Infinity Two. Through Infinity One, we’ve advanced engineering and prototype work that strengthened system understanding and contributed to early supply chain development for fusion projects. These experiences now guide the decisions shaping Infinity Two’s conceptual design, ensuring the engineering approach reflects lessons learned from earlier stages of fusion development.
Our contribution to Infinity Two is grounded in the project’s specific needs and the partnership of utility leadership, state support and private‑sector innovation. This collaboration reflects global momentum in fusion, where utilities and developers are working together to define a viable path toward commercialization. Global energy demands, advancements in nuclear technologies and new utility‑fusion partnerships underscore the importance of creating an approach that’s scalable globally and connects innovation with established delivery systems. Infinity Two is contributing to that model by demonstrating how fusion can move through planning, engineering and regulatory preparation in a coordinated, credible and safe way.
Scaling from pilots to programs
Infinity Two is part of a larger, global effort to demonstrate how fusion can be delivered at scale. TVA and Type One Energy’s collaboration positions the Tennessee Valley region at the center of an emerging fusion commercialization pathway, exemplifying how utilities, innovators, integrators, and regulators can make faster progress by working together.
By combining a utility’s delivery discipline with a developer’s technology innovation, an integrator’s program orchestration, and a state-centric regulatory environment, the program demonstrates how new energy technologies can advance more efficiently when partnerships shorten timelines, reduce risk, and build credibility with regulators, investors and communities. This coordinated approach strengthens the pathway for fusion and reflects our broader commitment to delivering cleaner, more resilient and more sustainable energy solutions that help build a better world.
