History and Current Status of the Patuha Geothermal Power Plant (2011-2024)

The Patoha Geothermal Power Plant, located in the province of Galut, West Java, Indonesia, is an important energy project promoted by Marubeni Corporation and Toshiba Energy Systems Corporation. The power plant, which utilizes geothermal resources, began operation in 2014. With an initial output of approximately 55 megawatts, the plant operates on a scale that can meet the annual electricity demand of 150,000 households. Highly efficient geothermal steam turbines supplied by Toshiba were installed to reduce CO2 emissions by 430,000 tons per year. Marubeni is overseeing the entire project, and the electricity generated is being supplied through Indonesia's state-owned power company, PLN.

In the 2020s, the Patoha geothermal power plant achieved further technological innovation and efficiency improvements: in 2022, Toshiba Energy Systems introduced an AI-based trouble prediction and diagnosis system to analyze power plant operational data in real time for early detection of abnormal signs. As a result, the trouble occurrence rate was curbed by more than 20%, and the facility operation rate was significantly improved. In the same year, Toshiba Energy Systems began offering the predictive diagnostic system through IoT services for a fee, further improving power generation efficiency by reducing the number and duration of equipment stoppages.

Today, the Patoha geothermal power plant is a symbol of sustainable energy supply in Indonesia, contributing to the spread of renewable energy. PT Geo Dipa Energi (Persero), Indonesia's state-owned geothermal power company, is deeply involved in the operation of the plant and is working with Toshiba Energy Systems to improve power generation efficiency and develop technologies.

The Patoha geothermal power plant is attracting attention as a model case for projects in other regions in Indonesia, which has abundant geothermal resources, and is contributing to the promotion of renewable energy introduction internationally. The project is highly regarded worldwide as a successful example of efforts to combat global warming and achieve energy independence.
