Singapore – As stated in the ASEAN Economic Community (AEC) Blueprint 2025, ASEAN intends to actively support “green development” by promoting a sustainable growth agenda that enables the use of clean energy, including renewables. Thus, ASEAN has defined an aspirational regional target of 23 percent RE in total primary energy supply (TPES) by 2025 across the region. To reach this goal, AMS have also adopted national renewable targets. Regional cooperation in renewable energy (RE) deployment can bring benefits to reach sustainable energy goals more cost-effectively than in a purely national approach. Several important regional cooperation activities are already ongoing in ASEAN which directly or indirectly influence RE deployment and operation in the region. To enhance regional cooperation on RE in ASEAN, AGEP organised a focus group discussion (FGD) on 4 June 2016 in Singapore during the ASEAN RE Week. The FGD aims to verify previous assumptions of the study on regional RE cooperation efforts, and to fill the gaps in those assumptions, by digging information from the participants. These inputs are valuable to develop a study on regional cooperation on RE in ASEAN which is scheduled to be published in September 2017.
