This study is an evaluation of the design, implementation and impacts of the EBRD's Sustainable Energy Financing Facilities (SEFFs) from 2004 to 2013. The ‚Ç¨2.4 billion SEFF portfolio includes 27 facilities across 20 countries of operations, working with 90 local financial intermediaries. The facilities are packages of credit lines and grant financed technical assistance to participating financial intermediaries and sub borrowers to support energy efficiency and small scale renewable energy investments. The facilities often include incentive payments to ultimate beneficiaries ‚Äì small and medium sized enterprises and households. This study examines the extent to which SEFFs have met objectives and contributed to transition impact, and suggests ways to enhance performance going forward.
