The Workshop Reports capture insights, discussions, and recommendations from the project's four workshops. The Policy Brief highlights key opportunities and lessons learned to inform energy policy improvements and strengthen electricity supply systems through EES adoption. Together, these components provide a comprehensive overview of the project’s findings and actionable recommendations for promoting EES adoption and market setting in the region.
