As for the electricity network, the progress of the ASEAN Power Grid Project is laudable since various studies of planting-up optimization and transmission interconnection have been accomplished through the Head of ASEAN Power Utilities/Authorities (HAPUA)
as well as some border transmission systems have been implemented by the mutual countries. With the future interconnected power grid, ASEAN member countries that have excess electricity supply will be able to sell its power to neighbouring countries with supply shortages, further encouraging more efficient regional energy resource management.
