Green Energy Tariff (GET)

The Green Energy Tariff (GET) is the PhP/kWh price awarded to each winning bidder in a Green Energy Auction (GEA) . It is the central pricing output of the GEAP and replaces the fixed administrative rate of the Feed-in-Tariff (FiT) for non-hydro RE technologies.

Pricing Mechanics

The GET operates on a pay-as-bid basis: each winning bidder receives its own offered price, not a uniform market-clearing price [DC2021-11-0036, §5.3, 2021-11-03]. This design rewards developers who bid competitively and prevents lower-cost projects from free-riding on a higher clearing price set by the marginal winner.

The GET is expressed in PhP/kWh and reflects actual energy generated [DC2021-11-0036, §5.2, 2021-11-03].

GEAR Price (Ceiling)

The Green Energy Auction Reserve (GEAR) Price is the maximum offer price per RE technology, set by the ERC before each auction round:

• First round: ERC must issue GEAR within 60 days of the Notice of Auction [DC2021-11-0036, §8, 2021-11-03]
• Subsequent rounds: within 30 days of Notice of Auction [DC2021-11-0036, §8, 2021-11-03]

Bids above the GEAR ceiling are disqualified. The GEAR thus functions as a price cap, protecting consumers while allowing competition below that ceiling.

ERC Resolution No. 2 s.2022 set the GEAR ceiling prices by technology for GEA-1 (June 2022).

FIT-All Funding Channel

In the base case (no DU opt-in), the GET is funded through the FIT-All mechanism:

1. TransCo enters into a Renewable Energy Payment Agreement (REPA) with each winning bidder
2. TransCo includes the GEA capacity and GET in its FIT-All petition to the ERC
3. ERC approves the FIT-All rate, which is socialized across all electricity end-users [DC2021-11-0036, §17.3, 2021-11-03]

This means GEAP procurement is collectively funded by ratepayers nationwide — the same channel used under FiT. The Opt-In Mechanism allows DUs to exit this pooled arrangement.

CSP Price Ceiling Function

The GET of the marginal (highest-priced) winning plant per technology serves as the price ceiling for any DU that conducts its own separate Competitive Selection Process (CSP) to meet RPS obligations [DC2021-11-0036, §14, 2021-11-03]. This anchors private bilateral procurement to the publicly discovered auction price.

Relationship to FiT

The GET administratively adopts the FIT regulatory framework (ERC Resolution No. 16, Series of 2010) for post-auction procedures — including COE-GET issuance and ERC Certificate of Compliance. The COE-GET is treated as equivalent to the FiT Certificate of Endorsement for eligibility purposes [DC2021-11-0036, §16, §9.12–9.13, 2021-11-03]. The key difference is that the GET price is competitively determined rather than administratively set.

DC2023-09-0027 (September 2023) made this equivalence explicit in §9.13: the GET is the FIT to which the Winning Bidder is entitled, and the COE-GET is the Certificate of Endorsement for FIT Eligibility — not a separate or additional charge against the FIT-All Fund [DC2023-09-0027, §1, 2023-09-26].

Non-FIT GET — A Different Animal (DC2023-10-0029 + DC2024-03-0010)

DC2023-10-0029 introduced the Non-FIT Green Energy Tariff (Non-FIT GET) for GEA-3 technologies (geothermal, impounding hydro, pumped-storage hydro). It shares the pay-as-bid principle with the standard GET but differs in two important ways:

ERC approval is part of the price itself. The Non-FIT GET is defined as the Price Offer “approved by the ERC” [DC2023-10-0029, §4(b), 2023-12-12] — not merely the bidder’s offered price. The ERC evaluates bids using its own published parameters and criteria before approving them. Under DC2021-11-0036, the GET was simply “the price offered by the Winning Bidder” (§5.3) — ERC’s only role was setting the ceiling.

Funded through WESM, not FIT-All. The Non-FIT GET is collected and settled through the WESM by IEMOP via a top-up/flowback mechanism (see Digest: DC2023-10-0029 — Non-FIT-Eligible RE Technologies in the GEAP §7). There is no TransCo REPA and no FIT-All involvement. This means Non-FIT GET costs fall on WESM trading participants rather than all electricity consumers nationwide.

Non-FIT GET indexation (DC2024-03-0010). DC2024-03-0010 (March 2024) required the ERC’s PDM for Non-FIT GEAP to “include indexation as may be determined by the Commission” [DC2024-03-0010, §3, 2024-03-25]. This is a separate indexation regime from the FIT-track GET indexation (DC2025-03-0004/DC2025-06-0009) — the ERC determines it as part of its PDM rulemaking, not through the FIT Rules framework.

PSH GET — Capacity-Based Variant (DC2024-09-0028)

DC2024-09-0028 (September 2024) introduced a further distinction within the Non-FIT GET for Pumped-Storage Hydropower (PSH):

• Non-FIT GET for PSH: expressed in PhP/kW/h (per kilowatt of available capacity per hour), not PhP/kWh. PSH bids on its capacity to inject and/or draw electricity, not on energy delivered [DC2024-09-0028, §1(b), 2024-09-10].
• Price Offer for PSH: the price in PhP/kW/h for Available Capacity, excluding pumping cost (net of house load) [DC2024-09-0028, §1(c.2), 2024-09-10].
• Settlement: Total GEA Amount for PSH = Σ (Available Capacity × Non-FIT GET × duration); Total Trading Amount includes both Energy and Reserve Market revenues (not just WESM energy spot) [DC2024-09-0028, §3, 2024-09-10].

See Pumped-Storage Hydropower (PSH) in GEAP for the full PSH settlement mechanics.

GET Indexation — FIT-Track (DC2025-03-0004 + DC2025-06-0009)

DC2025-03-0004 (March 2025) introduced explicit GET indexation for all GEAs conducted after the circular’s effectivity (GEA-4 onward), subject to ERC determination in accordance with the FIT Rules [DC2025-03-0004, §3, 2025-03-09].

DC2025-06-0009 (June 2025) then clarified this critically: the GET indexation is a one-time adjustment only — not annual. The “notwithstanding the FIT Rules” proviso in new §17 of DC2021-11-0036 explicitly overrides the FIT Rules’ annual adjustment mechanism. The single adjustment may be applied at any point between issuance of the Certificate of Award and commencement of commercial operations [DC2025-06-0009, §2, 2025-06-09].

Two distinct indexation regimes now exist:

Prior to DC2025-03-0004, the FIT-track GET was interpreted as a fixed pay-as-bid price. Neither amendment retroactively affects GEA-1, GEA-2, or GEA-3 GETs.
