Star Energy Geothermal and ABB Collaborate on Wayang Windu Modernization

Enhancing Geothermal Operations

Star Energy Geothermal (SEG), a subsidiary of Barito Renewables, has entered into a significant collaboration with ABB to modernize the Wayang Windu geothermal power plant in West Java. The 230.5 MW facility, comprising three units, is being upgraded with ABB's cutting-edge technology to enhance operational efficiency and reliability.

Key Technological Advancements

The modernization effort focuses on implementing ABB's Ability™ Symphony Plus distributed control system (DCS) across Units 1 and 2. This advanced system enables SEG to manage operations more effectively, improve stability, and reduce downtime. The upgrade also includes a modernized Human Machine Interface (HMI) that will facilitate smoother operations and prepare the facility for the integration of Unit 3, which is currently under development.

Strategic Significance

This partnership represents a significant step in SEG's commitment to optimizing Indonesia's geothermal potential. With Indonesia possessing approximately 40% of the world's geothermal reserves, the modernization of Wayang Windu contributes to the national goal of achieving 7,200 MW of geothermal capacity by 2025, as outlined in the National Energy General Plan (RUEN) 2020-2024.

Industry Context and Future Prospects

The geothermal sector in Indonesia remains ripe for development, with only about 10% of the estimated 24,000 MW potential currently utilized. SEG, which also operates facilities at Gunung Salak and Darajat, is poised to play a crucial role in expanding this capacity. The company's efforts at Wayang Windu, combined with ABB's technological expertise, demonstrate a strong commitment to advancing Indonesia's renewable energy landscape.

Supporting Indonesia's Energy Transition

The modernization project aligns with broader industry trends, as 87% of Indonesian companies surveyed by ABB Energy Industries Asia in 2025 anticipate increasing their use of renewable energy by more than 20% over the next five years. By leveraging ABB's innovative solutions, SEG is not only enhancing the reliability of the Wayang Windu facility but also contributing to Indonesia's transition towards a low-carbon future.
