Toshiba Energy Systems & Solutions Corporation (Toshiba) has received an order to supply a steam turbine and a generator from PT Inti Karya Persada Tehnik (IKPT), a subsidiary of Toyo Engineering Corporation, and the EPC contractor for the Patuha Geothermal Power Plant Unit 2 in West Java, Indonesia.

This plant is operated by PT Geo Dipa Energi (Persero), an Indonesian state-owned enterprise. Unit 2 is scheduled to come online in 2027 and will have a maximum continuous rating gross base generating capacity of 60.3MW. This marks Toshiba’s second recent order for a power generation system for a geothermal power plant in Indonesia, following a similar order for the Wayang Windu Geothermal Power Plant Unit 3, announced in October 2024.

As the world’s second-largest producer of geothermal power, Indonesia is endowed with abundant geothermal resources, with an estimated capacity of approximately 30GW. The country’s demand for electricity is escalating as its economy expands. While the Indonesian government is committed to addressing global environmental concerns and aims to achieve carbon neutrality by 2060, it must simultaneously increase power generation capacity. As part of its latest ‘Electricity Supply Business Plan (RUPTL 2021-2030),’ the government aims to boost power generation capacity by around 40.6GW by 2030, with geothermal power contributing 3.35GW, or roughly 8% of the total.

This includes the expansion of the Patuha plant, located on the outskirts of Bandung in West Java, approximately 200km southeast of Jakarta. The expansion will double the plant’s capacity, bringing the total to 110MW.

Toshiba has already made significant contributions to Indonesia’s stable power supply, delivering six steam turbines and generators for geothermal plants with a combined capacity of 311MW.

This includes equipment for the Sarulla Geothermal Power Plant, one of the largest geothermal facilities in the country, as well as for Patuha Geothermal Power Plant Unit 1 and Lumut Balai Geothermal Power Plant Unit 1.

Unit 1 has deployed EtaPRO, Toshiba’s proprietary IoT service for equipment performance monitoring, diagnostics, and predictive problem identification, all of which contribute to enhanced plant uptime and reliable power generation operations.

Toshiba Power Systems Division vice president Takehiko Matsushita said: “I am confident that the performance and reliability of our steam turbine and generator will prove our capabilities as a trusted partner for all kinds of geothermal projects.

“We have an extensive geothermal product lineup, ranging from 1MW to 200MW, and have executed numerous projects in Japan and overseas, helping our customers to make use of a constant and clean source of energy. We will continue to develop and promote geothermal solutions that support a sustainable future.”
