ISPyPSA

An open-source capacity expansion modelling tool based on the methodology and assumptions used by the Australian Energy Market Operator (AEMO) to produce their Integrated System Plan (ISP). Built on PyPSA.

This README is a quick reference. For detailed instructions, tutorials, and API documentation, see the full documentation:

• Getting Started - Installation and first model run
• Configuration Reference - All configuration options
• CLI Guide - Command line interface details
• API Reference - Python API for custom workflows
• Workflow Overview - How the modelling pipeline works

Installation

pip install ispypsa

Or with uv:

uv add ispypsa

Quick Start

1. Download the example config and edit paths for your environment
2. Run:

# Download ISP workbook and trace data
ispypsa config=ispypsa_config.yaml download_workbook
ispypsa config=ispypsa_config.yaml download_trace_data

# Run complete workflow (capacity expansion + operational model)
ispypsa config=ispypsa_config.yaml

CLI Reference

Common Options

# Override config values on command line
ispypsa config=config.yaml create_plots=True create_and_run_capacity_expansion_model

# Skip optimisation (build network only)
ispypsa config=config.yaml run_optimisation=False create_and_run_capacity_expansion_model

# Force re-run even if up-to-date
ispypsa config=config.yaml -a create_ispypsa_inputs
