ADB has approved a $180 million loan to PT Geo Dipa Energy to support 110-MW capacity expansion at the Dieng and Patuha geothermal fields in Indonesia.
The Asian Development Bank (ADB) has approved a $180 million loan to support the expansion projects of PT Geo Dipa Energy (Geo Dipa) at the Dieng and Patuha geothermal fields in Java, Indonesia. This additional financing will focus on supporting project completion against increasing costs and sustaining progress toward the country’s clean energy and climate goals.
Geo Dipa seeks to expand installed capacity by 55 MW each at the Dieng and Patuha geothermal fields. Earlier this year, the company announced that the well testing phase for the planned expansion work has been completed, spanning a total of 18 wells. Commercial operations of both Dieng Unit 2 and Patuha Unit 2 are planned for 2027. EPC contracts had recently been signed for both Dieng and Patuha.
“ADB is pleased to partner with the Government of Indonesia in advancing the country’s sustainable energy transition,” commented ADB Country Director for Indonesia Jiro Tominaga. “PT Geo Dipa Energy plays a catalytic role in driving the next phase of geothermal development. We look forward to continuing our close collaboration to expand Indonesia’s geothermal capacity and accelerate the shift toward a cleaner, more resilient energy future.”
As part of its community strategy focused on women, GDE allocates funds to improve women’s livelihoods through support for women-led small businesses and scholarships. It also promotes gender balance across its staff and contractors by integrating gender-sensitive approaches in its operations.
Back in 2020, the ADB had approved a $300 million loan for the 110-MW capacity expansion project, as well as another $35 million loan from the Clean Technology Fund. Earlier this year, the ADB had also signed a $92 million loan to support the expansion of the Muara Laboh geothermal power project of PT Supreme Energy Muaralaboh.
