Renewable energy from hydropower for Sumatra

Project details

HydropowerGet to know the project

The power supply on the Indonesian island of Sumatra is still heavily dependent on fossil energy, and the population's demand for electricity is growing.

Our carbon offset project in the north of Sumatra contributes to feeding more electricity from renewable energies into the power grid and improving the security of supply. The run-of-river hydroelectric power plant uses the flow of the Asahan River for energy production and the natural lake Toba as water inflow. This way, the project does not require large dams, which keeps the impact on the environment low. Electricity is generated by two 90 megawatt turbines, which supply about 1,208,500 megawatt hours annually. This saves an average of 1,021,070 tonnes of CO₂ annually that would otherwise have been released through the use of fossil fuels.

In addition, the project has created around 30 long-term jobs for the operation and maintenance of the plant.

How hydropower contributes to climate action

Hydropower plants use the energy of water to generate electricity. The energy is harnessed by passing water through a turbine. Under the pressure of the water, the turbine turns and transfers this energy to a generator, which converts kinetic energy into electricity. This principle applies to all types of hydroelectric power plants: from small run-of-river power plants to pumped-storage power plants on bodies of water like lakes. In many parts of the world, electricity is still primarily generated from fossil fuels. Clean hydropower can replace some of this emission-intensive energy and thus verifiably save carbon emissions. In most hydropower projects, the electricity is fed into a regional power grid, diversifying the energy supply and improving energy security in areas affected by power shortages and blackouts. Often, these projects also create jobs for the local population. Hydropower projects thus make an important contribution to clean energy supply as well as contributing to the UN Sustainable Development Goals (SDGs). Hydopower 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

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).

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.

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.

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.

Check out this project

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.

Climate projects go through third-party validation and verification. Validation happens early in the project life cycle and ensures that the project design is in line with current processes and requirements. This phase often also involves field visits with on-site interviews and analyses. Auditors are accredited, impartial assessors who have to be approved as a validation and verification body (VVB) by the standards body.

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.
