MESSAGEix Workshop

The aim of the workshop is to help new users of the MESSAGEix modelling framework getting started with their modelling work. The main features of the “framework” are introduced, and the use cases of some features are shown. The user can learn how to build an energy model and how to represent some policy constraints in their energy scenarios. For information about the model, its structure, mathematical formulation and much more, please see the documentation.

Learning objectives

The learning objectives of the workshop are the following:

  • Gaining a good understanding of energy systems modelling.
  • Getting to know the main features of MESSAGEix.
  • Building an energy model and solving it.
  • Applying further policy constraints to the model.
  • Getting insights on version control, testing and documentation in software development.
  • Understanding collaborative model development and continuous integration (GitHub).

Needed requirements

The workshop is designed to be accessible for users with different backgrounds and levels of experience with the modelling. However, there are some pre-requisite knowledge and skills which you should go through before getting started, including:

  • Elementary computer programming (preferably in the Python or R language);
  • Fundamental concepts of mathematical modelling, optimization, and data analysis; and
  • Energy systems (e.g., energy supply, energy conversion technologies, and demand sectors and their linkages).

For a complete list, plus links to learning resources, see “Pre-requisite knowledge & skills" repo in the documentation.

Installation MESSAGEix

Installing MESSAGEix before you're getting started with the workshop is highly recommended. Complete instructions are provided in the documentation on the “Installation” page of the documentation.

To successfully work through this workshop, we emphasize a few points from the instructions:

  • If you are not already familiar with the other installation methods, you should use Anaconda to install the framework.
  • Under the “Tutorials” page, you can download some simple models developed using MESSAGEix. To run these sample models, you need to install the Jupyter notebook software from Anaconda Navigator.

You can check our GitHub pages, where common issues and solutions are discussed: https://github.com/iiasa/message_ix/discussions
