Assessing the sustainability challenges for electricity industries in ASEAN newly industrialising countries

Rapid social and economic progress in fast developing countries such that among the countries in the Association of Southeast Asian Nations (ASEAN) have driven substantial growth in electricity consumption in this region. Whilst this represents significant societal and economic development, it has potentially growing adverse environmental impacts. This raises a concern on sustainable development in the electricity sector in this region. This study evaluates key sustainability challenges in the electricity industries in the five largest energy consumers in ASEAN: Indonesia, Thailand, Malaysia, the Philippines and Vietnam. The 3A's energy sustainability objectives: Accessibility, Availability and Acceptability are used as the sustainability analytical framework. This study also draws together a set of associated indicators and criteria within the analytical framework to analyse the status of the electricity industries in these countries. The analysis shows that key sustainability challenges in the ASEAN-5 are attributable to satisfying rapid demand growth; enhancing security of electricity supply; and mitigating the increase in CO₂ emissions from electricity generation. Given the promising resource and technical potential in this region, renewable energy emerges as a favourable option to address these challenges; however, increasing the share of renewable energy in electricity generation requires considerable policy support. This study suggests that there is an opportunity for the ASEAN countries to strengthen regional collaborations through experience and resource sharing to enhance sustainability in the electricity industries. This study also highlights some of the key issues facing the electricity industry, and the need for new generation investment decision support tools which can address these issues.
