Han Phoumin

Energy Economist

Han Phoumin has about 18 years of experience working at various international and inter-governmental organisations and multi-disciplinary research consortiums related to energy market and technologies, environment, integrated water resource management, governance, and economic development in the region of ASEAN and East Asia. He specialised in economic development and policy and applied econometrics. Much of his career in the past 12 years revolved around power sectors, especially with sustainable hydropower development, renewable energy policy research (i.e., biomass power generation competitiveness studies, solar and wind), energy efficiency and conservation, clean coal technology, energy security, and energy demand and supply forecasting. He has been serving as an expert for APEC on energy security for oil and gas emergency responses since 2013 until now. He is also one of the peer review experts for Peru’s energy subsidy removal commissioned by USAID in 2015. He also has led a number of projects in the EAS region related to energy policy and planning, and also contributed articles and special issues for academic journals.
