Notes

v1.0.0 (2026-01-19)

This is the first tagged release of PyPSA-SPICE 🥳 and represents a complete, fully functional implementation of the model. It establishes the baseline for all future development and includes the core model formulation, execution and post-analysis workflows, the scenario configuration system, and comprehensive documentation.

Fixed

  • Resolve the filtering issue with regional filters when adding load for non-electricity ones and missing interconnection (51 by @nhlong2701)

Changed

  • Update PyPSA version to 1.0.6 and refactor code to adapt to new changes (54 by @nhlong2701)
  • Update scenario_config workflow and template structure (58 by @RichChang963)
  • Add maximum power generation constraint (59 by @RichChang963)

Notes

  • PyPSA version upgrade: We have upgraded PyPSA to v1.0.6 and encourage users to upgrade their environments (using conda env update -f envs/environment.yaml --prune) to ensure full compatibility with the latest features and improvements.
  • Simplification of initial project setup: The build_skeleton rule now automatically generates a scenario_config.yaml file, simplifying initial project setup.
  • New parameter in custom constraints: A new boolean control field, active, has been introduced for defining custom constraints within scenario_config.yaml. Users should update their configuration format as described in the documentation to maintain compatibility and avoid configuration errors.
