Greater Mekong Subregion countries are in varying stages of economic development but share common goals concerning energy security and environmental protection. Progress have been made in promoting renewable energy, clean fuels, and energy efficiency, but new energy solutions remain crucial to the subregion’s advancement.
The GMS Economic Cooperation Program Strategic Framework 2030 (GMS-2030) emphasizes cross-border power trade, establishment of regional grid codes, development of regional markets, and expanding clean energy investments with a greater role for the private sector.
The Regional Power Trade Coordination Committee (RPTCC) managed regional power trade in the subregion from 2004–2022. In July 2022, at the 29th RPTCC meeting, the committee formally transitioned to the GMS Energy Transition Taskforce (ETTF). Among other things, the transition to ETTF ushers in closer energy cooperation with the Association of Southeast Asian Nations (ASEAN) and its initiatives, such as the ASEAN Power Grid.
Energy consumption in the GMS countries has grown intensively as their economies develop, driven mostly by residential and industrial sectors. Demand is forecasted to increase materially over the medium term.
GMS countries have used different approaches to increase access to reliable, affordable, and low-carbon energy.

The Government of the Lao People’s Democratic Republic is increasing its electricity exports generated from its hydropower projects to its neighbors in the Greater Mekong Subregion, including Viet Nam. Lao PDR and Viet Nam have signed MoUs targeting to export 8,148 MW from Lao PDR to Viet Nam by 2030. Lao PDR also signed contracts with Viet Nam Electricity (EVN) to implement 25 projects with a combined capacity of 2,180 megawatts.
