Lessons from GEA-4 and the Road to GEA-5

Synopsis

In March, the Philippines Department of Energy (DOE) launched the fourth round of the Green Energy Auction (GEA-4), the first to include energy storage alongside renewable energy. With results expected to be finalised by October, this session comes at a pivotal moment for assessing how well the auction has delivered on its promise to accelerate storage deployment, and what needs to evolve as the DOE prepares for a potential fifth round.

This interactive panel discussion will dive into the outcomes of GEA-4 and zoom out to identify auction design best practices from across Asia that can ensure future rounds are even more impactful.

1. What do the GEA-4 results tell us about the effectiveness of current auction structures in driving storage deployment?
2. How did regulators determine tariff levels—and did those mechanisms succeed in attracting serious market players?
3. What design features could help GEA-5 better match market realities and investor expectations?
4. Which regional policy frameworks and auction models offer the most compelling lessons for the Philippines?
5. How can future auctions support revenue certainty for solar-plus-storage projects, especially in island and off-grid settings?
