USAID implemented the Catalyzing Clean Energy in Bangladesh (CCEB) Project to support energy sector development for energy security, economic growth, and climate change mitigation, build capacity to design and implement environmentally friendly policies and regulations, and increase utilization of clean energy approaches and technologies for energy sector development on a low carbon trajectory in Bangladesh. IBTCI was selected to evaluate CCEB’s efficacy across five thematic areas: improving the regulatory environment for clean energy development, strengthening analytical capacity for energy sector planning and policy making, promoting industrial energy efficiency and conservation, adopting demand side management programs for electric utilities, and conducting market analysis and development for improved cook stoves. IBTCI conducted key informant interviews (KIIs), focus group discussions (FGDs), and a field survey of improved cook stoves (ICS) end users in field visits to Bagerhat, Chapai N’gonj, and Gaibandahi. IBTCI’s evaluation team interviewed 184 relevant stakeholders, including central government officials, energy infrastructure and business stakeholders, and CCEB implementing partners and local subcontractors. Additionally, a risk assessment framework (RAF) was developed to determine the CCEB Project’s likelihood in achieving expected development outcomes and potential secondary outcomes during implementation.
