- A project is a container for related scenarios, for example all the scenarios exploring one research question or country
- A scenario explores a single possible future for the electricity system, based on your assumptions about demand, technology, and policy
1. Create a project
From your workspace, click New Project, give it a name, and create it. You can rename or delete a project later from the project page.2. Create a scenario
Open your project and click New Scenario. The form has a few core fields plus a Configuration section that sets the shape of your model.Name and research question
- Name: a unique name for the scenario (e.g. Growth economy)
- Research question (optional): a short description of what the scenario explores (e.g. A high-growth economy with increased energy demand). This is also a useful starting point for AMP.
Geographies and spatial resolution
Choose the geographies your scenario covers, then a spatial resolution that controls how finely those geographies are divided into nodes:| Resolution | What it means |
|---|---|
| National | The whole country is modelled as a single node. |
| Regional | The country is split into multiple interconnected nodes (e.g. states, islands, or grid zones), so the model can represent electricity flows between them. |
| Multi-national | Multiple countries are modelled together, with cross-border interconnectors. |
Model type
Choose the framework that fits your question:| Model type | Best for | Framework |
|---|---|---|
| Capacity Expansion | Multi-year, long-term investment planning at lower time resolution | TZ-OSeMOSYS |
| Dispatch | A single year of operation at high time resolution | PyPSA |
Timeline
Set the years your scenario covers:- Capacity Expansion runs over a range: pick a Start and End year
- Dispatch models a single year only
Temporal resolution
Temporal resolution sets how many time slices the model uses to represent variation within a year. Each scenario’s time slices are the product of parts of a year × parts of a day:| Resolution | Time slices | Detail |
|---|---|---|
| Low | 1 | A single annual average. |
| Medium | 32 | 4 parts of a year × 8 parts of a day. |
| High | 8760 | Full hourly detail (used for Dispatch). |
3. What happens next
Every scenario starts from a calibrated base model with sensible default inputs, so you can run it immediately to get a least-cost baseline. From there you can:Customise the inputs
Adjust any of the model’s input data types to reflect your assumptions. See Editing Scenarios for how.
Run the model
Click Run and follow the run statuses through building, solving, and results.
