General Information

Indonesia’s Economic Value of Carbon, or Nilai Ekonomi Karbon (NEK), Trading Scheme is a mandatory, intensity-based ETS for the power sector that was launched in early 2023. In its first phase spanning from 2023 to 2024, it exclusively targeted coal-fired power plants connected to the Perusahaan Listrik Negara (PLN) grid with a capacity of 25 MW or greater. In 2023, the ETS covered 99 coal-fired power plants, estimated to represent around 37% of the national power generation capacity or around 67.6% of the national coal-fired power plant capacity. In 2024, 47 additional coal-fired power plants were covered under the ETS, bringing the total number of covered installations in the scheme to 146. 

The Indonesian government has established intensity targets, known as “Technical Emissions Ceiling Approvals”, or Persetujuan Teknis Batas Atas Emisi (PTBAE). These targets determine the number of allowances that installations receive for each MWh of electricity generated. Covered entities must surrender allowances for all their covered emissions, with allocation based on PTBAE, emission intensity, and emission average. Additionally, entities have the option to purchase allowances via auctions. 

The majority of the plants covered by the ETS are operated by the state-owned electricity company PLN. The government anticipates a reduction of approximately 25.73 MtCO2e through the ETS in its first year.

Eventually, the Indonesia ETS is expected to function as a hybrid “cap-tax-and-trade” system, operating concurrently with a carbon tax. Facilities failing to meet their obligations under the ETS will be subject to this tax, the rate of which will be aligned with the domestic carbon market’s price.

The Indonesian Carbon Exchange (IDXCarbon) was officially launched in September 2023, under the supervision of the Financial Services Authority of Indonesia (Otoritas Jasa Keuangan, OJK).

In 2024, the scope of the ETS was expanded to cover installations with a capacity of 25 MW or more, adding another 47 coal-fired power plants to the scheme. According to current plans, captive coal-fired power plants (CFPPs) that are not connected to the electricity grid and gas power plants (gas fired power plants, gas engine power plants and combined cycled power plants) will join the ETS in its second phase, from 2025. 

Power

Emissions & Targets

1,070.5 MtCO2e (2022)

By 2030: 31.9% below BAU including LULUCF (unconditional, enhanced NDC); up to 43.2% below BAU including LULUCF (conditional on international support, enhanced NDC)

By 2060: Climate neutrality (“Long-Term Strategy for Low Carbon and Climate Resilience”, July 2021)

Size & Phases

CO2, CH4 and N2O

PHASE 1: Two years (2023 and 2024) 

PHASE 2: Three years (2025 to 2027)

PHASE 3: Three years (2028 to 2030)

Note: These phases apply exclusively to the power sector.

The total emissions limit under the Indonesian ETS is the sum of the bottom-up output-based emissions limits for all individual covered entities.

The Ministry of Energy and Mineral Resources (MEMR) establishes the PTBAE, or the emissions limit, for the power sector. This is based on: (i) actual emissions, which must be below the emissions reduction target set for the sector, and (ii) the carbon trading roadmap for the power sector.

PHASE 1: 

The ETS was applicable only to coal-fired power plants connected to PLN’s grid. The total emissions limit was approximately 256.8 MtCO2e.

The emissions limit for the power subsector for Phase 1 was as follows:

  • non-mine mouth coal-fired power plants with a capacity of ≥25 MW to <100 MW: 1.297 tCO2e/MWh
  • mine mouth coal-fired power plants with a capacity of ≥100 MW: 1.089 tCO2e/MWh
  • non-mine mouth coal-fired power plants with a capacity of 100 MW to ≤400 MW: 1.011 tCO2e/MWh
  • non-mine mouth coal-fired power plants with a capacity of >400 MW: 0.911 tCO2e/MWh

PHASE 2 and PHASE 3:

The emissions limits for the second and third phases have not yet been determined, but they are expected to be more stringent than in the first.

PHASE 1: Coverage was limited to coal-fired power generators connected to PLN’s grid only. Details on thresholds are provided below.

PHASE 2: The government plans to expand the scheme to include coal-fired power plants with capacity above 25 MW and not connected to PLN’s grid (captive CFPPs), gas-fired power plants, gas engine power plants and combined cycled power plants connected to PLN’s grid. 

PHASE 3: The expansion will encompass all fossil fuel power plants, including diesel power plants with a capacity of 2 MW or greater and coal-fired power plants with capacity below 25 MW regardless of their connection to PLN’s grid.

INCLUSION THRESHOLDS: In 2024, coal-fired power generation facilities with installed capacity exceeding 25 MW are included. Smaller coal and fossil fuel plants will be incorporated at a later point (see above).

The Ministry of Environment (MoE) has indicated that the government plans to implement emission caps for four additional sectors in the future: forestry, industrial processes and product use, agriculture, and waste management.

Point source

Installations/facilities

In 2023: 42 entities covering 99 installations

In 2024: 63 entities covering 146 installations

Note: The number of entities and installations is expected to continue increasing as new installations commence operations and additional categories are included, in line with the roadmap's expansions.

Allowance Allocation & Revenue

In Indonesia, allowances are referred to as Persetujuan Teknis Batas Atas Emisi Pelaku Usaha (PTBAE-PU).

PHASE 1: 

Auctioning: In the Indonesian ETS, auctioning is conducted through a system managed by IDXCarbon, where bid and offer instructions are matched based on a time and price priority scheme (refer to the ‘Market Design’ section).

  • Auction share: 0% (2024) 
  • Auction volume: None

To date, no auction has taken place. Details regarding auction shares and related requirements or provisions are yet to be determined.

Benchmarking: MEMR sets intensity targets based on cap/PTBAE, installations’ average emissions of the previous year, and installations’ average emissions intensity of the previous year. These targets dictate the number of PTBAE-PU allowances allocated for every MWh of electricity generated. If the necessary data is unavailable, allocation is based on comparison with similar plants of equivalent installed capacity. In the first year, allowances will be given 100% for free. For the second year or the following year, installations will receive either 75% or up to 85% of their allowances for free. The deduction percentage depends on the installation’s compliance with the ETS.

Covered entities that receive allowances must participate in trading. If they do not, they receive a written warning and free allocation for the next compliance period is reduced to 75%.

Not defined

Flexibility & Linking

Banking is allowed within phases, though PTBAE-PUs are valid for a maximum of two years from the end of the previous compliance period. Banking is not allowed across phases.

Borrowing is not allowed.

The use of domestic offset credits – known as carbon reduction units, or Sertifikat Pengurangan Emisi Gas Rumah Kaca (SPE-GRK) – is allowed. Credits equivalent to SPE-GRKs may also be used.

QUALITATIVE LIMITS: Offset credits must stem from mitigation activities from:

  1. New and renewable energy power plants;
  2. Transportation, construction, and industry including energy efficiency activities; or 
  3. Other activities in the energy sector.

They must also be issued on the national registry.

QUANTATIVE LIMITS: None

In 2023, 6,260 tCO2 in offset credits were retired, all from the Geothermal Lahendong project.

The Economic Value of Carbon NEK Trading Scheme is not linked with any other system.

Carbon tax: Indonesia carbon tax (upcoming)[1]

Domestic crediting mechanism: Indonesia Emissions Reduction Certification    


 

[1] The carbon tax is expected to be launched in 2025

Compliance

Covered entities must surrender one compliance unit (allowance or offset credit) per tCO2e emitted for all their covered emissions. 

The compliance period for the Indonesian ETS is one year, with trading occurring from 1 January to 20 April of the following year. Surplus allowances at the end of the trading period may be traded in the following period, provided it is within the same phase.

MONITORING: An MRV system is currently in operation in the industrial sector and the power generation sub-sector. Pilot MRV programs are also being conducted in the cement and fertilizer sectors. 

REPORTING: Reports are submitted to the MEMR through the Directorate General of Electricity via an online platform, the APPLE-Gatrik. These reports must be submitted by the end of January for the preceding year. Installations must report emissions of CO2, CH4, and N2O, expressed in units of CO2e.

VERIFICATION: Emissions must be verified by a third-party verifier that is accredited by the Komite Akreditasi Nasional (KAN), Indonesia’s national accreditation body. This verification should be completed by the end of March, following the January reporting deadline. Verifiers are required to adhere to the guidelines for GHG emission verification in the power subsector.

The plan was to concurrently implement carbon trading and a carbon tax, with the latter serving as a penalty mechanism. However, as discussions on carbon tax regulations continue and its implementation is postponed, an alternative enforcement approach was introduced:

  1. Should verified emissions exceed the allocated PTBAE-PU by the end of the period, allocations will be given according to the results of carbon trading transactions in the previous carbon trading period up to a maximum of 85% and the PTBAE-PU will be reduced by up to 15%.
  2. Entities which fail to report their GHG emissions or participate in carbon trading by the end of the period will see a 25% reduction in their PTBAE-PU. 

Market Regulation

MARKET PARTICIPATION:

Compliance entities, specifically those holding an “Electricity Supply Business License for Public Purpose” or “Electricity Supply Business License for Own-Use,” are eligible to engage in carbon trading.

MARKET TYPES

Primary:

In the primary market, allowances and offset credits are traded through a mechanism that may be activated upon request by the relevant ministry. This platform facilitates offset selling, with a potential reserve price set as low as IDR 1 (less than USD 0.01), and bids commencing from this figure or higher. As of January 2025, there have been no auctions conducted under this system, and specific details about auction shares, along with associated requirements and provisions, remain to be defined.

Secondary:

Operated by IDXCarbon, launched at the Indonesia Stock Exchange (IDX) in September 2023 and licensed by the Financial Services Authority (OJK), the secondary market encompasses:

  • Regular Market or ‘Continuous Auction’: Matching of bids and offers based on time and price priority, with minimum prices set at IDR 200 (USD 0.01) and governed by fraction price rules and an ‘auto rejection’ rule.
  • Negotiated Market: Facilitates the settlement of pre-agreed trades through the exchange, requiring details of counterpart, carbon units, price, and volume.
  • Marketplace: Enables project developers to list their projects and set prices.

IDXCarbon is integrated with the national registry, Sistem Registri Nasional Pengendalian Perubahan Iklim (SRN PPI), managed by MoE, ensuring the seamless transfer of carbon credits and preventing double counting.

LEGAL STATUS OF ALLOWANCES: PTBAE-PUs and SPE-GRKs are classified as securities, allowing their transfer and trade in the capital market.

EVALUATION BY MEMR

Instrument type: Quantity-based instrument 

Functioning: The MEMR evaluates on a regular basis the implementation of the ETS. If the evaluation reveals a shortage of allowances, the Minister and Director General may conduct additional auctions of PTBAE-PUs.
