The 4th Green Energy Auction (GEA-4) in the Philippines drew strong interest, securing 9.42 GW of renewable energy capacity subscriptions against the Department of Energy’s (DOE) installation target of 10.65 GW, reflecting an 88% subscription rate. 

The tender was initially launched in March 2025 (see Philippines Targets Over 9 GW RE Capacity Under GEA-4 Auction). 

According to the preliminary results of the 111 accepted bids from private developers available on the DOE website, the total added up to 9,432.6 MW, covering multiple technologies including ground-mounted, rooftop, floating solar, integrated solar with energy storage systems (IRESS), and onshore wind. 

Winning projects will need to start commercial operations between 2026 and 2029 and contribute to the country’s target of achieving a 35% renewable energy share in its power generation mix by 2030, 50% by 2040, and over 50% by 2050.

While there was a strong response across the board, the DOE says there is still unsubscribed capacity for floating solar, onshore wind, and IRESS. This will be offered for subscription to other qualified bidders with accepted bids that exceed the initial targets. 

“This mechanism ensures that unsubscribed installation targets are maximized under GEA-4, and no opportunity for RE development is left unutilized,” explains the department in an official statement. 

Winning bidders will now move forward with the post-auction process, which will ensure that the pledged capacities are fully achieved and technically verified for grid integration.
