Waste-to-Energy (WTE)

Waste-to-Energy (WTE) refers to technologies that generate electricity from municipal solid waste (MSW) and biomass waste, including landfill methane recovery. In the Philippines, WTE is treated as a renewable energy resource and is promoted by the DOE as both an energy supply option and a solid waste management solution for Local Government Units (LGUs).

RE Contract Framework (DC2024-06-0018)

Biomass and WtE projects are governed by RE Operating Contracts under Digest: DC2024-06-0018 — Revised Omnibus RE Guidelines (Revised Omnibus RE Guidelines, Chapter III). Key features [DC2024-06-0018, §§5–14, 2024-06-04]:

Contract types:

• BEOC (Biomass Energy Operating Contract) — for biomass resources
• WTEOC (Waste-to-Energy Operating Contract) — for WtE resources (municipal and industrial waste)

WtE definition: Energy systems converting non-recyclable waste through anaerobic digestion, direct combustion, or gasification, subject to RA 8749 (Clean Air Act) and RA 9003 (Ecological Solid Waste Management Act) [DC2024-06-0018, §6, 2024-06-04].

Eligibility: 100% foreign ownership is permitted — Filipino and/or foreign citizens or corporations may apply. No nationality restriction applies to biomass or WtE [DC2024-06-0018, §7.1, 2024-06-04].

Award mode: BEOC/WTEOC are awarded exclusively through Direct Application (no OCSP). The applicant identifies the project site; DOE verifies it is free and open [DC2024-06-0018, §8, 2024-06-04].

Own-use/non-commercial: Biomass/WtE projects for own-use or non-commercial purposes do not require a BEOC/WTEOC — registration under Chapter XI suffices [DC2024-06-0018, §8.2, 2024-06-04].

Land access requirement: Unlike other RE types, BEOC/WTEOC applicants must show proof of ownership or possessory rights over the project site at application (since Contract Area = project site, not an exploration block). Affidavit of acquired possessory rights is accepted if title is not yet transferred, but final proof must be submitted within 30 days of COA issuance [DC2024-06-0018, §9.10, 2024-06-04].

Contract terms:

[DC2024-06-0018, §§10, 12, 2024-06-04]

Contract stages:

1. Development Stage — final feasibility study through Financial Closing, construction, testing/commissioning, COC application
2. Commercial Stage — commences from ERC’s issuance of Certificate of Compliance (COC)

[DC2024-06-0018, §13, 2024-06-04]

COR: Issued upon proof of Financial Closing (or earlier, at the developer’s option upon BEOC/WTEOC award) [DC2024-06-0018, §11.5, 2024-06-04].

Additional investment: If capacity increases ≥30% due to additional investment, the developer may obtain an additional COR — resetting incentives under the RE Act [DC2024-06-0018, §14.1, 2024-06-04].

Policy Framework (DC2022-02-0002)

The DOE issued DC2022-02-0002 on 17 February 2022 — “Prescribing the Policies and Programs to Promote and Enhance the Development of Biomass Waste-to-Energy Facilities.” The circular promotes Biomass WTE as baseload renewable energy that simultaneously serves LGU solid waste management and adds power supply. It also specifically recognizes the repurposing of coal power plants into Biomass WTE systems as a covered development activity [DC2022-02-0002, Whereas clauses, 2022-02-17].

RE Classification (§5)

Biomass WTE Resources comply with the definition of renewable energy resources under Section 4(uu) of RA 9513 and are classified as RE resources [DC2022-02-0002, §5, 2022-02-17]. Eligible feedstocks = biodegradable organic fractions of industrial and municipal wastes (MSW) that can be converted through thermochemical, biochemical, or physico-chemical processes.

Eligibility Conditions (§6)

To receive benefits under the circular, a Biomass WTE facility must at all times be:

1. Duly registered with the DOE under the RE Act; and
2. Compliant with: RA 8749 (Clean Air Act), RA 9275 (Clean Water Act), RA 9003 (Ecological Solid Waste Management Act), PD 1586 (EIS System), RA 6969 (Toxic/Hazardous Wastes Act), RA 9136 (EPIRA) and its IRR, and all other technical standards for Biomass WTE operation [DC2022-02-0002, §6, 2022-02-17].

Policy Supports (§7)

REC eligibility (§7.1): For every 1 MWh generated from a duly registered eligible Biomass WTE facility, one (1) REC is granted under the RE Market . REC issuance follows the REM Rules (DC2019-12-0016) [DC2022-02-0002, §7.1, 2022-02-17].

20-year minimum PSA (§7.2(a)): For Biomass WTE facilities embedded within a Distribution Utility’s uncontracted supply, the recommended minimum PSA term is 20 years [DC2022-02-0002, §7.2(a), 2022-02-17].

CSP exemption (§7.2(b)): Eligible Biomass WTE facilities are exempt from the Competitive Selection Process in accordance with Section 2.2.1.3 of DC2021-09-0030 (the 2021 CSP amendment circular) [DC2022-02-0002, §7.2(b), 2022-02-17].

ERC Mandate (§8)

The ERC is directed to issue necessary rules and regulations for effective implementation within 60 days of the circular’s effectivity [DC2022-02-0002, §8, 2022-02-17].

Penalties (§9)

Non-compliance is subject to administrative penalties under Section 35(e) of RA 9513 and its IRR [DC2022-02-0002, §9, 2022-02-17].

Comprehensive Assessment

The DOE’s RE roadmap calls for a comprehensive nationwide assessment of WTE potential as part of its medium- to long-term R&D priorities [PEP 2023-2050 Vol. II, Figure 10, 2023; NREP 2020-2040, p.56, 2022].

Current Status (December 2023)

• 12 registered WTE facilities in the Philippines
• Aggregate installed capacity: 60.193 MW
• Additional WTE potential: 113.96 MW from 7 facilities under study

Notable examples include landfill methane recovery and power generation facilities:

• 1.5 MW facility in Payatas, Quezon City
• 8.19 MW facility in Rodriguez, Rizal

[PEP 2023-2050 Vol. II, p.42, 2023]

Legislative Agenda

The WTE Bill is pending in the Philippine Congress. The DOE supports its enactment as policy backing for further promotion and development of WTE facilities. The DOE encourages procurement of energy from WTE facilities in recognition of the technology’s twin benefits: LGU solid waste management and countryside electrification [PEP 2023-2050 Vol. II, p.47, 2023].

Floating Solar Note

Related to WTE but distinct: the DOE awarded 9 Solar Energy Operating Contracts (SEOCs) in 2023 for large-scale floating solar projects in Laguna Lake, with a combined capacity of 1,135.3 MW. These projects are within 2,000 hectares of pre-determined areas (PDAs) of the Laguna Lake Development Authority (LLDA) designated for RE development [PEP 2023-2050 Vol. II, p.42, 2023].

Strategic Context

WTE offers the following advantages within the Philippine RE mix [PEP 2023-2050 Vol. II, p.47, 2023]:

• Dispatchable base-load RE (unlike intermittent solar/wind)
• Dual benefit: solves the LGU solid waste problem while generating electricity
• Supports rural electrification and countryside development
• Part of the DOE’s R&D agenda under NREP (resource assessment of WTE potential nationwide)

The DOE’s RE roadmap calls for a comprehensive assessment of WTE potential in the Philippines as part of its medium- to long-term R&D priorities [PEP 2023-2050 Vol. II, Figure 10, 2023].
