Expansion of Geothermal Capacity in Indonesia

Toshiba Energy Systems & Solutions Corporation has secured a significant order for the supply of steam turbines and generators for the Patuha Geothermal Power Plant Unit 2, located in West Java, Indonesia. The order comes from PT Inti Karya Persada Tehnik (IKPT), a subsidiary of Toyo Engineering Corporation, and the Engineering, Procurement, and Construction (EPC) contractor for the plant. This latest order builds on Toshiba’s established role in supporting Indonesia’s growing geothermal energy sector. Unit 2 of the Patuha plant, slated to begin operations in 2027, will boast a maximum continuous gross generating capacity of 60.3MW, helping to meet Indonesia’s increasing electricity demands while contributing to its carbon-neutrality goals.

Indonesia’s Push for Geothermal Expansion

Indonesia, the world’s second-largest producer of geothermal energy, continues to expand its geothermal capacity to meet both domestic energy demands and environmental goals. The country’s vast geothermal resources, estimated at approximately 30GW, make it a key player in the global geothermal market. As part of the government’s Electricity Supply Business Plan (RUPTL 2021-2030), Indonesia aims to increase its total power generation capacity by 40.6GW by 2030, with 3.35GW expected to come from geothermal sources, accounting for about 8% of the nation’s energy mix. The Patuha geothermal plant’s expansion is a key part of this broader strategy, with plans to double the facility’s capacity to 110MW.

Toshiba’s Commitment to Indonesia’s Clean Energy Transition

This new order for the Patuha Geothermal Power Plant follows Toshiba’s recent success in securing similar contracts, such as the one for Wayang Windu Geothermal Power Plant Unit 3. Toshiba has played a key role in Indonesia’s energy transition, having already supplied six steam turbines and generators for geothermal plants in the country, contributing a combined capacity of 311MW. Notable projects include the Sarulla Geothermal Power Plant—one of the largest geothermal facilities in Indonesia—and Patuha Geothermal Power Plant Unit 1.

Reliability and Performance Enhancement with IoT Technology

Unit 1 of the Patuha plant has incorporated Toshiba’s proprietary IoT service, EtaPRO, which is designed for equipment performance monitoring, diagnostics, and predictive maintenance. This technology enhances plant reliability and uptime by providing real-time performance insights and identifying potential issues before they cause operational disruptions. The integration of this advanced technology underscores Toshiba’s commitment to providing not just equipment, but also reliable and sustainable solutions for geothermal power generation.

A Vision for a Sustainable Future

Toshiba’s geothermal product portfolio spans capacities from 1MW to 200MW, with a proven track record of executing successful projects both in Japan and internationally. As part of its long-term strategy, Toshiba aims to promote the development of geothermal energy solutions that support a sustainable future. With this new order for the Patuha Geothermal Power Plant, Toshiba strengthens its position as a trusted partner in the geothermal energy sector, contributing to Indonesia’s efforts to meet its carbon-neutrality targets and to the global transition to renewable energy sources.
