The Energy Regulatory Commission (ERC) has approved the final reserve price structure under the fourth round of the Green Energy Auction Program (GEA4), setting the policy framework for the competitive bidding of over 10,000 megawatts (MW) of renewable energy capacity.
Under the approved pricing structure, the ERC set reserve prices at ₱5.68/kWh for rooftop solar, ₱4.4832/kWh for ground-mounted solar, ₱6.5258/kWh for floating solar, ₱6.0859/kWh for onshore wind, and ₱5.4028/kWh for solar paired with battery energy storage systems (BESS).
In line with the GEA policy, renewable energy developers must bid at or below these rates to secure fixed, incentivized contracts. The Department of Energy (DOE) confirmed that the GEA4 auction will take place on 2 September 2025, with bid validation scheduled for 17 September. Endorsements and award notices will follow in October, culminating in the official announcement of qualified participants on 22 October.
GEA4 targets a total of 10,653 MW—comprising 9,553 MW from solar and wind technologies for rollout from 2026 to 2029, and an additional 1,100 MW from solar-BESS hybrid projects.
According to the DOE, GEA4 “opens new avenues for project development across the archipelago, particularly in areas with limited available land,” highlighting the strategic inclusion of floating solar in the country’s mainstream renewable mix.
