Clean energy flows across Southeast Asia
Singapore is importing renewable electricity from its neighbours. The LTMS-PIP project shows that regional energy trade is possible. It connects Laos, Thailand, Malaysia and Singapore. The initiative supports clean energy and regional cooperation.
Singapore is taking significant steps to strengthen regional energy cooperation. It is participating in the Lao–Thailand–Malaysia–Singapore Power Integration Project, known as LTMS-PIP. The initiative was launched in 2022. It is the first multilateral renewable energy trading mechanism in Southeast Asia. The project serves as a model for cross-border electricity exchange.
A regional model for clean energy trade
The project connects Laos, Thailand, Malaysia and Singapore in a shared energy system. Laos, often referred to as the region’s battery, supplies surplus hydroelectric power. Thailand and Malaysia act as transit and distribution hubs, while Singapore imports the electricity. This arrangement demonstrates the technical and commercial viability of long-distance renewable energy trade.
LTMS-PIP is being implemented in two phases. The first phase delivered up to 100 megawatts of hydropower from Laos to Singapore using existing infrastructure. The second phase expands capacity to 200 megawatts and introduces multidirectional power flows, including additional supply from Malaysia.
Financing and future potential
Beyond infrastructure, the success of regional energy trade depends on financing and governance. LTMS-PIP highlights the need for investment in transmission upgrades, harmonised regulations and flexible contract structures.
According to a report led by McKinsey and published by Singapore’s Economic Development Board, Southeast Asia must significantly increase its annual renewable energy capacity additions to meet net-zero targets. The region will require approximately 1.1 trillion US dollars in annual investment to meet climate goals.
Singapore currently relies on imported natural gas for around 95 per cent of its electricity. By diversifying its energy sources through cross-border renewable imports, the country is enhancing its energy security and sustainability. The LTMS-PIP provides a foundation for future initiatives, such as the Brunei–Indonesia–Malaysia–Philippines Power Integration Project. It shows that multilateral renewable energy trade is both feasible and scalable.
