The Ayeyawady–Chao Phraya–Mekong Economic Cooperation Strategy (ACMECS) currently has varying energy resources, but abundant resources – especially hydropower – are underutilised because ACMECS countries have no existing bulk transmission network covering their entire area. The high-voltage transmission network can bring multiple benefits, including reduced fuel costs of thermal power generation, reduced CO2 emission, improved electricity access, and the ability to consolidate higher shares of variable renewable energy.  

For this report, a cost–benefit analysis on utilising high-voltage cross-border interconnections for power trade in ACMECS was carried out. The study was conducted with the support of experts from Cambodia, Lao PDR, Myanmar, Thailand, and Viet Nam, who shared relevant data. Following the outcome of this study, ACMECS countries need to continue exploring how they move the regional grid towards a more accessible, affordable, and sustainable future power sector through the transmission highway concept.
