Renewable energy generation across the Southeast Asian region has been long driven by the deployment of hydro-based solutions. Between 2000 and 2016, hydropower capacity in the region grew from nearly 16 GW to 44 GW, according to International Renewable Energy Agency (IRENA).The region currently deploys two types of hydropower – large hydro and small hydro. Countries in the Mekong River Basin, including Cambodia, Lao PDR, Myanmar and Vietnam (CLMV), are leading this growth.
