Indonesia's energy-intensive commercial and industrial sectors present a compelling, largely untapped opportunity to scale up energy efficiency (EE) as a driver of decarbonisation, cost reduction, and green economic growth. Small and medium enterprises (SMEs) are a central focus of this assessment: they make up over 99% of Indonesian businesses, face the most acute barriers to EE financing, and illustrate the scale of opportunity that remains underserved by green finance. This study estimates over 871,000 SMEs sit in energy-intensive industrial and commercial activity alone.
To size the investment opportunity concretely, this assessment also analyses four well-documented commercial and industrial sectors: hotels, shopping malls, hospitals, and manufacturing. These sectors are chosen for the quality of available data and the replicability of EE projects within them. These sectors include businesses of all sizes, from SME-scale operators to large enterprises; they are presented not as a literal subset of the 871,000 SMEs, but as representative, bankable market segments that demonstrate the breadth of EE business opportunity across Indonesia's economy, for SMEs and larger players alike.
