MANILA, Philippines — The Philippines has emerged as a leading catalyst in Southeast Asia’s renewable energy (RE) transition through 2030, according to the International Energy Agency.

The latest IEA report showed that the Philippines, alongside Vietnam and Indonesia, would boost the region’s RE surge, with major capacity gains expected between 2025 and 2030.

In particular, the Philippines is poised to add around 15 gigawatts (GW) of new RE capacity, with solar and onshore wind making up 90 percent of the expansion.

“This represents a five-GW (around 50 percent) increase over the previous forecast, owing to completed and ongoing competitive auctions,” the IEA said.

Recently, the Department of Energy (DOE) attracted over 9,400 megawatts (MW) of capacity during the fourth green energy auction (GEA-4) round, with delivery dates between 2026 and 2029.

GEA-4 covers ground-mounted solar, roof-mounted solar, floating solar, onshore wind and integrated solar with energy storage systems.

This followed the successful bidding of over 6,000 MW of impounding hydro, pumped storage hydro and geothermal contracts under GEA-3.

“If challenges such as grid connection delays, high financing costs, land access restrictions and permitting bottlenecks are addressed, growth could be 90 percent higher, putting the country on track to exceed its targeted 35 percent renewable electricity share by 2030,” the IEA said.

Currently, renewables account for only 22 percent of the Philippines’ power mix, with coal remaining dominant at about 63 percent.

To ensure the timely delivery of new RE projects, the DOE is looking to allow power producers to build associated transmission facilities.

The move is designed to support effective grid integration of new projects and address constraints in the transmission network.

Across the region, ASEAN countries are on track to add over 95 GW of new RE capacity over the next five years, the IEA said.

Notably, more than half of these additions are likely to come from solar photovoltaic projects.

According to the IEA, Vietnam leads ASEAN’s RE growth and accounts for over 40 percent of total capacity additions, followed by Indonesia at 20 percent.

Both countries are expected to accelerate their expansion efforts through 2030.
