This study, conducted up to December 1st 2024, addresses the challenges of financing energy efficiency (EE) projects in Indonesia, focusing on perceived high risks, low profitability, and limited awareness of energy savings as a business case. It highlights a lack of market demand for EE, small transaction sizes, and insufficient evaluation capacities among local financial institutions (LFIs) as key barriers. These challenges hinder the implementation of EE measures, which could otherwise reduce electricity demand, save costs, and help achieve Indonesia’s climate commitments. The study’s purpose is to evaluate global and local EE financing mechanisms, identify best practices, and provide actionable recommendations for Indonesia.
