Philippines Announces 9,378 MW Green Energy Auction Round 4

The Philippines’ Department of Energy (DOE) has released the Terms of Reference (TOR) for the fourth round of the Green Energy Auction (GEA-4), aiming to add 9,378 MW of renewable energy capacity from solar (ground-mounted, rooftop, and floating) and onshore wind projects.

Key Highlights of GEA-4

• First Auction to Include Renewable Energy + Energy Storage Systems (IRESS):
  • 1,100 MW of solar capacity will be paired with Battery Energy Storage Systems (BESS).
• 20-Year Supply Contracts:
  • Winning bidders will secure long-term power supply agreements starting from their project's commercial operation date.
• Regional Capacity Allocation (2026-2029):
  • 2026: 2,372 MW (Luzon: 1,040 MW, Visayas: 252 MW, Mindanao: 120 MW, including 50 MW of solar with storage).
  • 2027: 2,362 MW (Luzon: 1,976 MW, Visayas: 350 MW, Mindanao: 36 MW, with 50-100 MW of solar + storage).
  • 2028: 2,766 MW (Luzon: 2,025 MW, Visayas: 705 MW, Mindanao: 36 MW, with 100-150 MW of solar + storage).
  • 2029: Additional capacity expansions in solar and wind.

New Guidelines and Bidding Process

• Updated Green Energy Auction Program (GEAP) Guidelines:
  • Revised supplier qualifications.
  • A structured pricing mechanism with tariffs indexed to feed-in-tariff rules by the Energy Regulatory Commission (ERC).
• Bidder Registration & Qualification:
  • Developers must hold a renewable energy service contract or a certificate of authority under the Revised Omnibus RE Guidelines.
  • The GEA Bids Evaluation and Awards Committee will publish a list of qualified bidders before the pre-bid conference.
• IRESS Technical Requirements:
  • 0.2 inverter ratio relative to registered solar capacity.
  • Minimum round-trip efficiency of 85%.
  • At least four-hour storage duration.
• Registration Timeline:
  • Starts one working day after the ERC publishes the green energy auction reserve price.

Philippines' Renewable Energy Progress

• 2023 Green Energy Auctions:
  • 3.43 GW of renewable energy projects awarded.
  • 610 MW of floating solar projects contracted.

With GEA-4, the Philippines aims to accelerate clean energy adoption, enhance grid stability, and support its commitment to a renewable-powered future.
