January 2021 | Geothermal power production in West Java, Indonesia

Geothermal power

Underground reservoirs of steamy hot water are the fuel for geothermal power. It can be piped to the surface to drive turbines that produce electricity without pollution.

Indonesia is an extremely tectonically active country, with over 400 volcanoes – 130 of which are active. This geologic activity gives the nation huge potential for producing electricity in a cost-effective and reliable method – from a renewable, sustainable energy source. As of 2019, Indonesia has the second-highest installed geothermal energy capacity in the world, behind only the USA.


This award-winning project supports the Phase 2 development of the Wayang Windu geothermal power station in West Java, Indonesia.

Phase 2 involves the development of a 117MW Geothermal Power plant, an addition to the existing 110MW power station build as part of Wayang Windu Phase 1. The project is located 40km south of Bandung in West Java, Indonesia. Renewable energy generated from geothermal steam displaces electricity generated primarily from coal and diesel in the existing grid.

The project has a positive impact on the local economy, and also runs a large outreach and community programme which includes the development of household biogas alternative energy projects, the plantation of over half a million trees and improvement of 13,000 hectares of land, and supporting local education and health, through the provision of over 3,000 local scholarships and health clinics.

As a result, the Wayang Windu geothermal project has won many awards from the Indonesian Ministry of Environment and Ministry of Energy.
