This report provides a comparative analysis of 24 LTES and 36 scenario-based LT-LEDS from a total of 45 countries and concludes by highlighting the advantage of basing LT-LEDS on scenarios.

This report synthesises experts’ views on how to improve scenario comparison studies to gain insights for the clean energy transition and maps out the motivation, focus and methods of such studies.

Scenario modelling has become an essential tool to lay the groundwork for clean, reliable, sustainable future energy systems.

A collaborative campaign, launched at the 9th Clean Energy Ministerial (CEM) in May 2018 and co-ordinated by the International Renewable Energy Agency (IRENA), calls for wider adoption and improved use of model-based LTES. This brochure highlights findings from the first-year of the LTES campaign.

This report highlights the findings from AVRIL (“Addressing Variable Renewable Energy in Long-term Energy Planning”), a project by IRENA that has identified the best practices in long-term planning and modelling to represent high shares of VRE.
