Phl backs ASEAN drive for fully interconnected energy grid

With the Philippines set to chair the Association of Southeast Asian Nations (ASEAN) next year, the Department of Energy (DOE) has vowed to help advance the region’s vision of an interconnected and sustainable energy future.

Speaking at the Singapore–International Energy Agency Forum, Energy Secretary Sharon Garin said ASEAN member states are united in ensuring reliable and affordable power while accelerating the shift toward cleaner energy sources.

“Our experience in linking the country’s three major island grids shows how greater connectivity enhances system reliability and flexibility,” Garin said. “This mirrors the principles behind the ASEAN Power Grid—by linking our systems, we can better utilize our diverse resources and strengthen supply stability.”

Garin underscored that an interconnected ASEAN energy system would not only drive the clean energy transition but also promote shared progress and prosperity across the region. She noted that achieving regional renewable energy goals would require closer cooperation and coordinated planning among member states.

“Without integration, each country will have to maintain costly reserve capacities. Through interconnectivity, we can reduce these costs and improve system reliability,” she explained.

The energy chief cited significant progress under the ASEAN Power Grid framework, with half of the priority projects identified in the ASEAN Interconnection Masterplan Study Phase III already operational. However, she emphasized that more work remains in harmonizing technical standards, market design, and investment strategies.

“To unlock the full potential of regional interconnection, cooperation must go beyond building physical links,” Garin said. “We must align our national policies so that our systems can operate seamlessly across borders.” TRACY CABRERA
