The World Bank’s Board of Executive Directors has approved a US$380 million loan to develop the 1,040-MW Upper Cisokan pumped storage hydropower plant, the first such facility in Indonesia.
The aim of developing this project is to improve power generation capacity during peak demand while supporting the country’s energy transition and decarbonization goals, according to the World Bank.
“The Indonesian government is committed to reduce greenhouse gas emissions through, among others, development of renewable energy, energy conservation, and use of clean energy technology. Emission reduction in the energy sector will be driven by new and renewable energy generation and application of energy efficiency,” said Arifin Tasrif, Minister of Energy and Mineral Resources of the Republic of Indonesia.
Over 80% of the power generated for the Java-Bali grid, which supplies electricity to 70% of the country’s population, comes from fossil fuels. A key measure to support Indonesia’s decarbonization agenda is the development of energy storage to enable integration of renewable energy into the grid. Pumped storage hydropower plays a crucial role in this approach.
The Upper Cisokan pumped storage hydropower plant, to be located between Jakarta and Bandung in West Java province, will have significant power generation capacity to meet peak demand, provide significant storage capacity to enable a larger penetration of renewable energies and, because of its close location to two large demand centers, will alleviate increasing transmission loads on the grid. As a result, a more environmentally friendly and reliable supply of electricity will benefit consumers in Java and Bali.
“We are excited about this project as it will be the first of its kind for Indonesia. It represents a turning point for Indonesia’s decarbonization pathway. The World Bank will continue to support Indonesia in its efforts to achieve resilient, sustainable, and inclusive development that will benefit the people of Indonesia now and in the future,” said Satu Kahkonen, World Bank Country Director for Indonesia and Timor-Leste.
The project will help enhance the system flexibility and efficiency in balancing supply and demand, and therefore improve the reliability and quality of electricity services in Java and Bali. It also aims to support the government to integrate variable renewable energy into the Java-Bali grid, and to do so in an environmentally and socially sustainable manner.
