Scenario Builder, redesigned: faster, more auditable and built to grow
Filter hundreds of thousands of input rows and chart multiple scenarios side by side - on the same modelling engine you already trust.
Summary
We rebuilt Scenario Builder's interface from the ground up so it can carry everything we're building to speed up clean energy planning, with the same modelling engine, data, and results you know underneath.
You can now filter and sort across hundreds of thousands of rows of input data, chart any number of scenarios side by side, and move around your workspace in a couple of keystrokes with global Cmd+K search.
It's a faster, clearer way to work that feels familiar from the first click - try it out with your next scenario run.
Why we rebuilt the interface
Scenario Builder is our no-code, cloud-native energy systems modelling platform. It cuts the time it takes to model an energy system by giving you out-of-the-box datasets and cloud infrastructure. You can go from a question to a result without standing up your own modelling stack.
We have a lot planned for the Scenario Builder, and we wanted an interface that could carry all of it. So we rebuilt it on a modern, scalable foundation, designed to grow without breaking what’s already there.
What stayed the same
The important part hasn't changed. The modelling engine, the input data, and the results are exactly as before, so you get the same trusted outputs you've always relied on. What's new is the speed, the clarity, and how much of your work you can see at once.
What's new, and what it means for you
You can now work across hundreds of thousands of rows of input data right in the interface, filtering and sorting to find exactly what you need. That means you can model at national or multi-region scale with the full dataset in front of you and the detail you need close at hand. The more of your system you can hold in view, the better grounded the scenario you build from it.
You can also chart any number of scenarios together and compare total capacity, generation, emissions, and more, with filtering by one or more nodes within each scenario. Seeing your pathways lined up next to each other is usually the moment the trade-offs become clear, and a clearer trade-off makes for a better-supported decision.
Getting around is quicker, too. Press Cmd+K to jump straight to any project or scenario. Caching and preloading mean the things you're about to need are ready before you ask for them, so pages load, scenarios open, and your train of thought stays intact.
And there's more room to think. A consistent, focused layout keeps your attention where it should be, sidebars resize and collapse as you need them, and dark mode is built in, by popular request.
What's next for Scenario Builder
This redesign is the foundation for what comes next: a more interactive platform with more powerful data visualisation to help you explore your scenarios and reach decisions faster. This is the first step, and there's plenty more on the way.
Try it with your next scenario run
Open two of your existing scenarios and chart them side by side, or filter a national dataset down to the nodes you care about. If you already use Scenario Builder, nothing you rely on has moved, and if you're new, you can sign up and build your first scenario on the built-in datasets within minutes. Log in today, start modelling, and tell us what you think.
