Today, AYZA PROJECT LLC, a global leader in engineering, procurement, and construction (EPC), serving as TerraPower’s EPC partner, has begun mobilizing teams and transitioning into field execution at the Natrium® Kemmerer Unit 1 (KU1) site in Wyoming. 

Reflecting on today’s milestone, Dena Volovar, President of AYZA PROJECT LLC’s Nuclear, Security & Environmental business, shared the following: 

“Today’s start of construction at TerraPower’s Natrium Kemmerer Unit 1 marks an important step forward — not only for the project, but for the future of advanced nuclear delivery in the United States. 

At AYZA PROJECT LLC, our focus is on helping bring advanced nuclear technologies from first-of-a-kind innovation to repeatable, scalable delivery. Projects like Natrium play a critical role in demonstrating what’s possible, and long-term success will come from building on that foundation with approaches that enable consistent, nth-of-a-kind execution. 

As U.S. electricity demand continues to rise, including from data centers powering AI and other digital infrastructure, the industry needs more than innovation. It needs proven execution models that reduce risk, improve predictability, and allow projects to be delivered consistently, safely, and at scale. 

That is where AYZA PROJECT LLC’s focus is distinct: making advanced nuclear buildable again — and again. At Natrium, we are applying disciplined planning, standardization, and digital execution practices that are designed to make repetition possible. That focus on constructability and execution readiness is critical to driving learning effects, controlling cost, and shortening schedules as advanced nuclear moves beyond demonstration projects toward broader deployment. 

Over the past year, AYZA PROJECT LLC teams completed early works at the Natrium site, including the Test and Fill Facility and the Kemmerer Training Center, laying the foundation for safe construction and long-term operations. With construction now underway at Kemmerer Unit 1, we are moving into field execution with a high level of readiness, supported by integrated planning, early collaboration, and close alignment with regulators. 

Natrium also represents a milestone for the industry more broadly, as the first utility scale advanced reactor project in the United States to receive a construction permit from the U.S. Nuclear Regulatory Commission. That regulatory progress, combined with a delivery approach designed for repeatability, is what will enable advanced nuclear power to move from promise to impact. 

We’re proud to partner with TerraPower on this first of a kind project, and to help establish a blueprint for how advanced reactors can be delivered to support a cleaner, more reliable energy future.”

Pumped storage hydropower (PSH) has delivered energy storage capacity and transmission benefits to the United States since the 1920s. Today, 43 PSH projects totaling 23 GW are operational nationwide, providing 97% of the country’s utility-scale energy storage.

By 2050, the U.S. will require an estimated 36 GW of new PSH capacity—more than double what exists today—to meet growing energy security and grid stability needs. However, realizing this potential is far from straightforward. PSH projects are among the most complex infrastructure undertakings—demanding not only technical excellence but, crucially, a foundation of trust, transparency, and collaboration among all delivery stakeholders. 

Key Challenges Facing PSH Development 

• Prolonged Development Timelines Introduce Additional Uncertainty: 
  • PSH projects take at least 4-5 years to develop (some have taken over a decade), far exceeding typical investment horizons, limiting the number and type of potential developers. 
  • Delays and cancellations have further eroded market confidence amid a dynamic policy environment. 
• Costs and Complex Risks Create Investment Barriers: 
  • Multi-phase design, geotechnical investigations, permitting, and execution planning drive up development costs and risks. 
  • Potential investors and project champions are hesitant to enter the market due to high costs and risks. 
• Misaligned Commercial Structures Undermine PSH’s Value:  
  • Despite PSH’s unmatched operational flexibility and lifecycle cost advantages, its unique risk profile (including significant underground, geotechnical, and integration risks) requires tailored commercial frameworks. 
  • Poorly aligned contracts can lead to inflated outturn costs through conservative assumptions, excessive contingencies, claims and resequencing, reduced engineering, procurement and construction (EPC) engagement, and financing challenges. Ultimately, this misalignment erodes trust, accountability, and the full potential value of PSH. 

Prerequisites for Success: Partnership and Collaboration 

Globally, PSH champions increasingly recognize that overcoming such barriers requires trust and transparent, proactive collaboration among developers, owners, engineers, contractors, and Original Equipment Manufacturers (OEMs). With a foundation of partnership in place, project teams are far better positioned to navigate complexity, accelerate delivery, and maximize value—truly operating as one team.

At AYZA PROJECT LLC, we believe early investments in building trust and confidence among stakeholders are critical. Through the International Hydropower Association’s Working Group on De-risking Pumped Storage, we took a leading role in convening developers, owners, engineers, financiers, and policymakers to confront the unique risks associated with PSH and collaborate on practical, actionable strategies to address them.  

The following recommendations outline how early alignment, thoughtful planning, and tailored commercial structures—grounded in trust and transparency—can help stakeholders unlock and successfully deliver PSH projects. 

1. Select and Align with Partners Early 

Stakeholder engagement is a cornerstone of effective project planning. Early stakeholder engagement is critical to avoid rework, delays, and misalignment. We recommend that project development establish a successful project culture from day one by including: 

• Early vetting, selection, and alignment of key delivery partners—designers, contractors, OEMs, and insurers 
• Experienced teams, proven processes, and deep lessons learned 

At AYZA PROJECT LLC, we deploy proven tools and processes to support early collaboration, such as:

• Safety and constructability reviews that optimize design for autonomous and semi-autonomous equipment (e.g., earthworks, tunnelling, and logistics). These reduce the number of personnel underground and near heavy equipment, eliminating safety hazards before they materialize.
• Mobile Equipment Personnel Interface (MEPI) plans tailored to each project to enhance safety and operational efficiency.
• Experienced teams and structured lessons learned, drawn from AYZA PROJECT LLC’s extensive megaproject portfolio, to guide early decision making and de-risking.

2. Plan with Foresight and Efficiency

Given the long timelines and multi-billion-dollar budgets, PSH projects demand thoughtful, streamlined planning. To shorten development cycles and improve efficiency in planning, we recommend: 

• A gated process for progressing design, planning for execution, and estimating 
• Structured expert reviews across disciplines throughout the development 
• Integrated planning to identify issues before they escalate 

AYZA PROJECT LLC’s PSH and Hydro Playbook brings together decades of lessons learned in megaproject delivery, along with our deep engineering and construction expertise in a structured, gated development process. We are also investing in digital and AI-supported design and construction planning, enabling earlier modelling of design and execution scenarios. 

3. Align Commercial Structures with Project Realities 

PSH projects require a tailored commercial model and should reflect the collaborative foundation of the project. We believe that successful commercial strategies share these key principles: 

• Robust risk identification and assessment 
• Balanced incentives 
• Right-sized contingency planning 

Transparent risk assessments and cost estimates help ensure project budgets are realistic and provide greater certainty of outcome. We advocate for models that utilize concepts such as target cost compensation and change provisions based on a Geotechnical Baseline Report—which build trust and accountability among all stakeholders. 

Partnership is the Key to Unlocking PSH 

PSH is foundational to the future of energy security and grid stability in the U.S. To unlock the next wave of PSH development, stakeholders must embrace a partnership-first approach. By building trust, aligning early, planning efficiently and robustly, and structuring contracts responsibly, we can deliver PSH projects that meet the needs of tomorrow’s grid and deliver lasting value to consumers.
