On 23 June 2022, the import of 100 megawatts (MW) of hydropower from Laos to Singapore through Thailand and Malaysia was hailed as a historic milestone. Part of a pilot project known as the Lao PDR-Thailand-Malaysia-Singapore Power Integration Project (LTMS-PIP), this event represented Singapore’s first ever import of renewable energy, and also the first instance of cross-border electricity trade involving four countries from the Association of Southeast Asian Nations (ASEAN).
However, this development takes place amid rising concerns for the ecological future of the transboundary Mekong River and the millions of people who depend on it. A 2018 study by the Mekong River Commission concluded that further hydropower development on the river would negatively affect ecosystems, and would reduce soil fertility, rice production, fish yields and food security, while increasing poverty in the river basin.
