From Concept to Confidence:
Accelerating Power Plant Design
nTtau Digital
We help clients design power plants and critical systems faster, smarter, and more cost-effectively. We combine practical engineering experience with our unique AI-powered design platform, NuPlant, to automate complex power plant simulations. This makes design work up to 10× faster, reduces costs, and gives our clients clear, validated results to support confident decisions.
Whole Fusion Power Plant Design & Costing
Transparent, Independent, Investment-Ready
​
We deliver clear, independent cost analysis for the entire power plant - from core to site boundary. Our reports stand up to external scrutiny and give investors what they need for funding and planning. Every figure is backed by physics simulations, providing real numbers, not rough estimates, so teams can forecast accurately, reduce surprises, and secure investment sooner.
On-Demand Support
Support When and Where You Need It
​​
We provide targeted project support to solve challenges and keep things moving. Whether during design, build, operation, or maintenance, our flexible expertise fits your needs.
By automating time-consuming tasks and streamlining workflows, we help teams cut delays, reduce costs, and deliver faster, without disrupting existing systems.
Advanced Simulation Support
Expert Help on Complex Challenges​
​
When projects face difficult physics or design questions, we provide the simulation and analysis to find clear answers. Our work enables quick, confident decisions, reduces risk, and removes bottlenecks, keeping teams focused, projects on schedule, and milestones within reach.

Who we support
Fusion Companies
Move from concept to verified design up to 10× faster.
Validate designs across thousands of scenarios to avoid costly rework and produce investment-ready results that meet milestone deadlines. Free up engineers to focus on innovation, not repetitive tasks and build credibility with investors through verified, data-backed results.
Engineering, Procurement and Construction (EPC) Companies
We provide transparent, independent cost analysis for full plant builds.
Our tools integrate easily with existing project systems and enterprise engineering software, producing faster, more accurate design outputs that meet safety and regulatory standards.
External validation of designs and assumptions supports bids, reduces risk, and exposes technical or cost trade-offs early.
Investors
We provide independent costings and analysis that support credible investment decisions.
Early validation of design performance and economics reduces First-of-a-Kind (FOAK) risk, enabling projects to reach milestones faster and with greater transparency.
Our third-party verification builds confidence that systems will perform as designed, cost what they should, and deliver long-term value.
Leading the Way to a Sustainable Future
The need for clean, reliable power has never been greater. Traditional design and costing for complex energy facilities are slow, expensive, and difficult to validate.
At nTtau Digital, we change that.
​
Our AI- powered design platform, NuPlant, automates simulation workflows and links engineering outputs to transparent, investor-ready economics for the entire facility. This substantially reduces the risk and cost of First-of-a-Kind (FOAK) pilot plants by compressing design cycles and improving confidence in every decision.
By making the process faster, more efficient, and more reliable, we help clients save time and money, meet key milestones, and accelerate the deployment of fusion power.
