Wayang Windu Geothermal Power Plant, West Java, Indonesia | 227 MW Facility

Wayang Windu is a geothermal power plant located in West Java, Indonesia, with an installed capacity of 227 megawatts. Operated by PT. Star Energy, the facility plays a significant role in Indonesia's geothermal energy sector, which is among the largest globally due to the country's volcanic geology. The plant is situated in the mountainous region near the Wayang Windu volcano, leveraging high-temperature geothermal reservoirs for power generation. The plant utilizes geothermal steam to drive turbines, a technology that produces low emissions compared to fossil fuel plants. Indonesia's regulatory framework for geothermal energy includes the Geothermal Law No. 21/2014 and supporting regulations that promote renewable energy development. Wayang Windu's capacity places it in the large-scale category for geothermal plants, which typically range from 10 MW to over 200 MW. The facility's operational status is active, contributing to the Java-Bali power grid. Environmentally, Wayang Windu provides a low-carbon energy source, reducing reliance on coal and natural gas. Geothermal plants have a small land footprint and emit minimal greenhouse gases, though they can release trace amounts of hydrogen sulfide. The plant supports local communities through employment and energy access, aligning with Indonesia's goals to increase renewable energy share to 23% by 2025. Its location in a seismically active region requires robust engineering to ensure safety and reliability.

Wayang Windu's geothermal operation produces negligible CO2 emissions compared to fossil fuel plants, contributing to Indonesia's climate targets. The plant's location in a volcanic area means it taps into a renewable heat source, but also requires careful management of geothermal fluids to prevent land subsidence and induced seismicity. The facility's 227 MW capacity displaces significant coal-fired generation, reducing local air pollutants like SOx and NOx. Proximity to populated areas is moderate, with the plant situated in a rural region of West Java.
