Jakarta, Indonesia – This year, two projects of Geothermal Power Plant (PLTP) will be built. The project is, Patuha 2 PLTP and Dieng PLTP 2.
PT Geo Dipa Energi (Persero) as the project contractor has carried out the groundbreaking of two projects, each with a capacity of 60 megawatts.
Geo Dipa President Director Riki Firmandha Ibrahim said the plant was an expansion of two Geo Dipa-operated plants, namely Dieng 1 with a capacity of 60 MW and Patuha 1 with a capacity of 55 MW. The plan is for the two plants to be built to operate in 2023.
“This project has an investment value of US $ 300 million and funding is provided by the Asian Development Bank (ADB),” Riki said.
According to him, the groundbreaking of the two projects is a step for the company to maximize its geothermal potential. At present, Geo Dipa has a geothermal potential of 1,200 MW. However, this potential has only been explored by 115 MW.
With this project, the Geo Dipa plant capacity is planned to reach 270 MW in 2023. Because, in addition to the expansion of plants in Dieng and Patuha, the company will also operate small-scale geothermal power plants with a capacity of 10 to 15 MW and 10 to 15 MW Organic Rankine Cycle Power Plant.
The plant is planned to be operational in 2020 and 2022.
“In addition, we are also conducting exploration in the Geothermal Working Area (WKP) of Arjuno Welirang in East Java and Telomoyo Umbul Temple in Central Java,” he said.
Meanwhile, the Director General of New and Renewable Energy of the Ministry of Energy and Mineral Resources FX Sutijastoto said the geothermal potential in Indonesia is quite large. But now the utilization of this potential is still minimal.
According to its data, geothermal potential in Indonesia reaches 39 thousand MW, but its utilization has only reached 1,948 MW.
The government hopes that geothermal utilization can rise to 6,310 MW in 2025 in accordance with the PLN Electricity Business Plan (RUPTL) 2019 to 2028. That is, the use of geothermal energy in the energy mix can increase from 5 percent to 11 percent in the same period.
“Of course this is very good, because in the next 2025, geothermal energy can reduce the dependence of fossil energy. Maybe around 11 thousand equivalent barrels of oil per day,” he added.
