Capacity Building


IRENA supports its Member Countries to assess the flexibility of their power systems. This is a critical consideration when planning for high shares of renewables, including maximum use of solar and wind power.

The IRENA FlexTool, developed with the VTT Technical Research Centre of Finland Ltd, helps to identify flexibility trends, gaps and cost-effective solutions to optimise national power systems. The freely accessible, open-source modelling tool reflects both capacity expansion and dispatch variables.

The training materials provided include:

  • Basic training – explaining key features to help new FlexTool users get started.
  • Modelling different flexibility options – demonstrating the tool’s use to address generation, storage and other system challenges.
  • Methodology – examining the underlying mathematical model and answering advanced modelling questions.
