PT Geo Dipa Energi plans to expand its geothermal power capacity by adding seven new units at the Mount Patuha Geothermal Power Plant (PLTP) in Bandung, West Java.
This expansion will fulfill a 400 MW power purchase agreement (PPA) with State power utility company PT PLN, as revealed by Ruly Husnie Ridwan, General Manager of PT Geo Dipa Unit Patuha. Currently, only one geothermal unit is operational, while eight units are planned.
The Patuha Unit 2 is expected to commence operations by 2027, with the third unit targeted for 2032.
Ridwan shared optimism that the remaining units could be operational within the next decade.
“We hope to see the completion of these additional units within the next ten years,” he said during a recent media tour with the Ministry of Finance in Bandung.
According to Ridwan, six of the new units will each have a capacity of 55 MW, while the last two will generate 35 MW each, bringing the total capacity across all units to 400 MW. The combined capacity of Units 1 and 2 alone will reach 110 MW.
The development of Patuha Unit 2 is being funded by a US$300 million (US$4.7 trillion) loan from the Asian Development Bank (ADB), equivalent to Rp4.6 trillion, with financing also extended for the Dieng Unit 2 geothermal plant.
Additionally, Geo Dipa is utilizing funding from the Clean Technology Fund (CTF), offering particularly low-interest rates.
“The ADB loan has an interest rate of 0.5 percent, while the CTF loan may be even lower,” Ridwan noted.
Electricity generated by Patuha Unit 2 will be fully purchased by PT PLN and connected to the Java-Madura-Bali (Jamali) grid, supporting reliable energy across the region.
The cost of electricity from PLTP Patuha is set at US$0.07 per kilowatt-hour (kWh), which is more competitive than other renewable energy sources, which generally range from US$0.09 to US$0.10 per kWh.
