The International Forum on Long-term Scenarios for the Clean Energy Transition brings together scenario practitioners in government, academia, technical institutions and the private sector to discuss how to strengthen the development and improve energy scenarios to guide the clean energy transition. It is the annual flagship event of IRENA's LTES Network and Clean Energy Ministerial LTES Initiative.

IRENA’s Long-term Energy Scenarios (LTES) Network provides a global platform to exchange knowledge and good practices in the use and development of model-based long-term energy scenarios (LTES) to guide the clean energy transition. It aims to promote wider and more effective use of LTES in government for energy and climate policy-making.

Key stakeholders involved in the LTES Network are:

  • Scenario users within government planning teams and policy-making institutions.
  • Scenario developers within government modelling teams or technical institutions supporting government.

The LTES Network focuses and aims to benefit members in the institutional aspects around three areas:

LTES network focuses

The LTES Network is built on the “Long-Term Energy Scenarios for the Clean Energy Transition Initiative” - a time-bound Initiative that IRENA has run since 2018 under the umbrella of the Clean Energy Ministerial (CEM).


Members of the LTES Network are given the opportunity to engage with the IRENA’s programmatic activities that include, but are not limited to:

Joining the network

Formal membership in the LTES Network is free of charge and open to both government institutions responsible for the development of official scenarios, as well as technical institutions that support governments in the development and use of such scenarios.
