Running a Model

If you haven’t imported output.json into SpineOpt yet, start in Building a Model.

🛠️ Step x: Select and Configure a Solver for MIP problems

MORPHE2US (via SpineOpt) supports various optimization solvers. Choose one based on your performance needs:

▶️ Step 1: Run the Model

Directly within Spine Toolbox:

  1. Left-click on the Project Execute window in Spine Toolbox.

  2. Monitor the log window for progress and any warnings/errors.

💡 Tip: For large models, expect longer runtimes. For fast iterations, start with short time horizons or fewer technologies.

📁 Step 2: View and Export Results

Once the model completes:

  • Open the output database to view results (automatically generated by SpineOpt).

  • Use Spine Toolbox visualizations or export data to .csv or Excel.

Typical outputs include:

Outputs

Description

Energy Flows

Hourly flows per technology and node

Invested capacity

Capacity additions by technology/year

Emissions

CO₂ emissions per time slice

Costs

By activity and node

🧰 Troubleshooting

If the model fails to run:

  • ❌ Infeasible model: Check constraints (e.g., demand too high, no valid tech)

  • ⚠️ Missing inputs: Ensure all time series and costs are present

  • 🐌 Too slow: Try a smaller horizon or simpler tech mix

Use the log window in Spine Toolbox for detailed error messages and solver output.

✅ Next Step: Analyze Your Results

Once your model runs successfully and results are exported, move to:
