The Association of Southeast Asian Nations (ASEAN) region is an economic zone of around 630 million people with regional gross domestic product of US$ 2.4 trillion (2015) growing on an average of 5.3 percent per year in the period 2007-2015. The demand for energy is immense due to the economic growth in the region driven by transport and industry sectors. However, energy demand and supply in individual ASEAN Member State (AMS) vary depending on available resources, as well as political and regulatory frameworks.
