Harnessing Indonesia's potential for geothermal energy

Project details

Geothermal energyGet to know the project

The project activity is comprised of a capacity upgrade of Gunung Salak Geothermal Power Plant from 3 x 55 MW to 3 x 60 MW. This is done by changing the turbine diaphragm and modifying the gas ejectors. The upgrade leads to an annual average of nearly 214 GWh of electricity to the connected JAMALI Grid. The supply of steam for the project, which is provided by the nearby Gunung Salak Geothermal fields is secured by an long-term Energy Sales contract. Indonesia is situated in the “Ring of Fire”, a global region with many volcanos. It’s great potential for geothermal energy resources are not yet fully exploited. The small proportion of the total energy mix is due to the high capital investment required for the development of geothermal energy utilization.

As geothermal power projects produce no end products in the form of solid waste (e.g. ash), they address the problem of solid waste disposal encountered by most other sources of power.

How does geothermal energy help fight global warming?

Geothermal power plants create emission-free energy from ground heat. The ground heat is used to heat water, and the resulting steam is used to drive turbines. The growth of renewable energy production is essential in limiting global warming and securing energy supplies for the future. The amount of emissions saved by a geothermal project is calculated using the baseline method: how much CO2 would be released by generating the same amount of energy using standard energy production methods for the region? Geothermal energy projects in the ClimatePartner portfolio are registered with international standards.

The project aims to contribute to these United Nations’ Sustainable Development Goals (SDGs).

Project facts

Type
Reduction

Climate projects generally fall into one of three groups: carbon reduction, carbon removal, or carbon avoidance. Carbon reduction projects reduce the amount of greenhouse gas emissions produced by a specific activity (e.g., improved cookstoves). Carbon removal projects remove carbon from the atmosphere by sequestering it in carbon sinks (e.g., reforestation). Carbon avoidance projects avoid greenhouse gas emissions entering the atmosphere (e.g., protecting forests from deforestation with REDD+ projects).

Location
Indonesia, Gunung Salak

Standard
VCS

All climate projects are based on international standards. They set processes and requirements which carbon projects must fulfill to be recognised as a proven method of reducing carbon emissions.

Technology
Geothermal energy

Climate projects demonstrably reduce, remove, or avoid greenhouse gas emissions. This is achieved with various technologies, ranging from nature-based solutions to social impact projects and renewable energies.

Registry ID
144

Most standards on the voluntary carbon market list their projects in public registries. The registries are used to store project data and track issuances and retirements of verified emission reductions. The registry ID can be used to identify projects in the standard registry.

Verified by
TÜV NORD CERT GmbH

Climate projects go through third-party validation and verification. Verification happens regularly after each monitoring period. A validation and verification body checks and assesses whether the values and project activities stated in the monitoring report are correct and verifies them. As with validation, visits to the project site are often part of the process.

Estimated annual emission reductions
112,520 t CO₂

This figure shows the estimated annual emission reductions calculated before the project started. The actual number of emissions saved in each monitoring period may differ. The background to this process is that in order to be registered as a climate project, the project operator must submit the calculation of the estimated emissions savings using the ex-ante methodology in a Project Design Document (PDD), which is similar to a business plan. This calculation is validated by an independent auditor. The values determined in the PDD are recalculated during regular monitoring periods based on actual project performance, documented in a monitoring report, and verified again by independent auditors at the end of the monitoring period to ensure a robust process. Independent verification thus provides ex-post verification of actual emission reductions. Verified emission reductions are not distributed until the savings have actually been made.

Four criteria for projects to meet quality thresholds

01. AdditionalityA project must lead to lower carbon emissions than would have occured without the project. Additionality also means that a project relies on financing from the sale of emission reductions, as the project would otherwise not be feasible and the upfront investment would be too high for project developers.

02. Exclusion of double countingThe carbon reduction may only be counted once and may not be counted again elsewhere, so a Verified Emission Reduction is retired once it has been used. This process is recorded in official registries.

03. PermanenceThe criterion of permanence ensures that carbon reductions or removals are ongoing and do not occur just once. This guarantees a long-term benefit for the climate. The minimum duration of a project depends on the underlying project technology.

04. Audit by independent third-partiesClimate projects must be audited regularly by independent auditors such as TÜV Nord. These auditors verify that the project is in compliance with the relevant standards. They also determine the volume of carbon emissions that have actually been avoided or removed.

The life cycle of a climate project

A climate project has a set life cycle consisting of various phases, from the feasibility assessment to the retirement of Verified Emission Reductions (VERs).

Project planning phase

The project developer reviews the general feasibility of the project, the project design, and the financing. Then, the Project Design Document (PDD) is prepared, which contains all the basic information about the project, such as the objective, location, timeline, and duration.

Validation

In this phase, independent auditors examine the PDD and the information it contains. This phase often also involves field visits with on-side interviews and analyses. Auditors are accredited, impartial assessors who have to be approved by the relevant standard as a validation and verification body (VVB). TÜV Nord/Süd, S&A Carbon LLC., and SCS Global Services are examples of VVBs."

Registration

Once validated, the project can be registered with a standard such as the Verified Carbon Standard or the Gold Standard. All high-quality climate projects are based on international standards. They provide the framework for project design, construction, carbon accounting, and monitoring. Recognised standards make the climate project system and the projects themselves resilient, traceable, and credible.

Monitoring

After the climate project has been registered, the monitoring begins. Here, the project developers monitor and document the data of the project activities and progress. The duration of the monitoring phase varies from project to project: it can cover two years, but documentation over five or seven years is also possible.

Verification

At the end of each monitoring phase, a VVB checks and assesses whether the values and project activities stated in the monitoring report are correct. As with validation, visits to the project site are often part of the verification process.

Issuance of Verified Emission Reductions

Once verified, the emission reductions that were confirmed in the verification phase can be issued as VERs. The steps of monitoring, verification, and issuance of VERs are repeated regularly and are therefore considered as a cycle.

Retirement of Verified Emission Reductions

Once a VER has been used, it must be retired. This process is also reflected in the registry. If the financing of a climate project is done through ClimatePartner, the VERs are bundled in a system certified by TÜV Austria and then retired on a regular basis. This ensures that each VER can no longer be sold and is only used once, preventing double counting.
