IRENA Session: Energy scenario communication for strengthened inputs and trustworthy outputs

Long-Term Energy Scenarios (LTES) Network


Side event at International Energy Workshop (IEW)

Freiburg, Germany - 25 May 2022, 12:40 – 14:00


IRENA’s Long-Term Energy Scenarios Network (LTES Network) aims to facilitate knowledge-sharing between scenario practitioners in the government sectors through the exchange of best practices and experiences to better plan the clean energy transition. Currently, it has 26 member countries and 12 partner institutions. This year, the network members and partners have chosen to prioritize “participatory processes” and “communication of scenario results” as key focus topics.


In this context, IRENA is organizing this side event with the aim of gathering experience from the scientific community to support government planners in improving their communication practices around energy transition scenarios, while gauging the interest of the IEW community in further participation in discussion with the LTES Network community.



The LTES Network's primary interests are to improve the development and use of scenarios by government planners in pursuit of the energy transition. Regardless of whether scenarios are implemented using quantitative models or not, national governments use scenarios to support policymaking. As the clean energy transition affects a broader range of stakeholders, including communities, businesses, industries and many others, LTES members consider it essential to strengthen the communication of scenarios, both in terms of quality and inclusiveness.


As the clean energy transition anticipates more complex interactions within the energy system, communication should entail clear messaging on methodologies, key assumptions, and key outcomes to ensure results are as transparent as possible, especially when quantification of long-term energy scenarios is performed using complex energy models. Various communication methods have been innovated and utilized to convey quantitative results of the scenarios developed. These methods have been propelled and coincided with the advancement of digital platforms, and scenario practitioners continuously seek to leverage such advancements to efficiently their vision of the future energy system, thereby both educating various stakeholders on energy and climate topics and building trust in those scenarios.


While communicating results from scenarios that are developed is vital for the reasons mentioned, two-way communication during the process of building scenarios ensures robust inputs into the process, leading to stronger and more inclusive scenarios that represent the visions of a broad spectrum of stakeholders.  More open and participatory processes are needed that involve a wider range of stakeholders to construct storylines for long-term scenarios. It is vital for these stakeholders to share challenges and visions, but also contribute to data, assumptions and other inputs. Scenario developers have used many modalities with varying frequencies, uses, and advantages to engage stakeholders and gather data. These modalities require different strategies and resources and can depend on the target of the scenario studies at hand.



By the end of the session, we aim to:

  • Exchange communication methods deployed in the scientific community to strengthen public trust and understanding of the future energy system and provide a clear signal of national ambitions to the wider international community;
  • Exchange innovative methods of stakeholder engagement deployed in the scientific community that can allow the development of inclusive and diverse national scenario storylines, provide robust input and data, and foster a trustworthy scenario-building environment;
  • Collect feedback on the ways that scientific communities have participated in the government LTES development process;
  • Gauge the interest of the IEW community in further exchanges on this topic with LTES members.



The session will feature 4 expert presentations on the subjects of communication around energy transition scenarios and stakeholder engagement and outreach, followed by a moderated discussion between the presenters. Comments will then be collected from participants to support and shape the development of future activities on this subject.
