Cambodia’s Green Energy Moment Has Arrived
Cambodia is entering a pivotal phase in its economic and energy development. As rapid industrialization, urban expansion, and deeper integration into global supply chains continue, one critical challenge has come sharply into focus: how to meet rising electricity demand in a way that is sustainable, affordable, and future-proof.
Over the past decade, Cambodia’s power sector has undergone a quiet yet transformative shift. A system once heavily dependent on imported fossil fuels and large-scale hydropower is now evolving into a more diversified energy mix, increasingly powered by solar, wind, biomass, and other renewable sources. As a result, green energy investments in Cambodia are accelerating at an unprecedented pace.
This momentum is being driven by a combination of supportive government policies, rapid growth in electricity demand, declining renewable technology costs, and mounting pressure from global investors and manufacturers to comply with ESG standards. Together, these forces are positioning Cambodia as one of Southeast Asia’s most attractive emerging markets for clean energy investment.
This article explores why renewable energy investment is accelerating in Cambodia, the key sectors driving growth, the incentives attracting investors, the challenges that remain, and what the future holds for the country’s green energy transition.
1. Cambodia’s Rapid Energy Demand Growth Is Reshaping the Power Sector
Cambodia ranks among the fastest-growing economies in ASEAN, with manufacturing, construction, tourism, and urban development driving a sharp and sustained rise in electricity consumption. Annual power demand has consistently recorded double-digit growth, fueled by several structural trends:
- Expansion of industrial zones and special economic zones
- Growth in export-oriented manufacturing, including garments, footwear, and electronics
