PT Geo Dipa Energi is expecting to add an additional 130 MW of geothermal power generation capacity at its geothermal plants of Dieng and Patuha. It is planning a 10 MW binary plant at Dieng and additional 60 MW units at Dieng and Patuha.

PT Geo Dipa Energi (Persero), a geothermal development company under the guidance of the Ministry of Finance, targets an additional installed capacity of 130 MW of geothermal power generation capacity to increase its total capacity to 250 MW over the next four years.

The company is targeting funding from the Asian Development Bank to complete its expansion of the Dieng and Patuha geothermal plants in 2023. The company is currently operating single units at its geothermal plants of Dieng and Patuha with a total capacity of 120 MW.

In 2021, the 10 MW expansion of the Dieng geothermal plant is expected to start operation. The company is planning with a 10 MW binary unit and is cooperating with PT SMI on the development as we reported in September 2018.

It is planned to then start operation of the additional 60 MW of Dieng Unit 2 and 60 MW of Patuha Unit 2 by 2023.

Riki F Ibrahim, President Director of Geo Dipa, said that to pursue the target of increasing capacity, the expansion for the Dieng and Patuha PLTPs is absolutely necessary. Geo Dipa is currently negotiating a loan from the Asian Development Bank (ADB).

Geo Dipa projects that the funds needed to develop PLTP are around US $ 300 million. The construction of Dieng Small Scale began this year. The company has prepared funds of US $ 23 million, specifically for developing potential in the Dieng operating area, Dieng Small Scale, Geo Dipa will collaborate and utilize funding from PT Sarana Multi Infrastruktur (SMI).

According to Riki, in the initial plan Dieng Small Scale should have been completed this year, but failed to do so because there were maintenance needs for production wells. “It will be onstream next year, because we will repair the wells too,” Riki said.

In addition to Dieng and Patuha, there are several Geothermal Working Areas (WKP), namely the Arjuno Welirang WKP, which covers Mojokerto, Pasuruan Malang and Batu City regions with a 180 MW reserve potential with exploration status; WKP Umbul Telomoyo Temple, which covers Semarang, Magelang, Boyolali, Tumegung and Salatiga Regencies with a potential reserve of 90 MW with exploration status.
