What We Do

Sustainability
A cornerstone of Singapore’s pursuit of energy sustainability is regional power grid integration. To strengthen energy resilience and achieve climate objectives, Singapore is actively advancing cross-border electricity trade through the ASEAN Power Grid initiative.

This approach enables the nation to access cleaner and more cost-effective renewable energy sources from the region. By 2035, Singapore aims to import around 6 gigawatts of low-carbon electricity, which could account for approximately 30% of its total power supply at that time.
Why Interconnections are Essential for ASEAN
The ASEAN Power Grid is pivotal in advancing the region's collective objectives of energy security, sustainability, and affordability.
Enhancing Energy Security
Backup Power: In the event of a power outage, an interconnected country can access electricity from neighbouring grids, minimising the risk of widespread or prolonged power supply disruptions.

Supply Diversity: Regional interconnections enable countries to leverage a broader mix of energy sources available across ASEAN, strengthening overall energy resilience.
Driving Sustainability and Decarbonisation
Unlocking Renewable Energy Growth: Southeast Asia holds significant renewable energy potential. Grid interconnections facilitate the development of the renewable energy sector.

Optimising Variable Energy: As renewable energy sources are intermittent in nature, a regional grid ensures a stable and continuous supply of clean energy.
Supporting Economic Efficiency and Growth
Resource Optimisation: By integrating electricity systems, it enables more efficient distribution and trading of surplus clean energy for the region.

Economic Synergy: A well-connected regional grid stimulates green job prospects and fosters economic growth for participating countries.
