The Kaishan Group, through wholly owned subsidiary KS Orka Renewables Pte. Ltd. (KS ORKA), has signed a Memorandum of Cooperation with PT PGE to utilize the waste heat and tail water from PGE’s existing geothermal power plants for further power generation. The agreement was signed during the 11th Indonesian Ministry of Energy and Mines New Energy Directorate (EBKTE) Exhibition in Indonesia.
PGE plans to expand the power generation capacity of their existing geothermal power plants by utilizing waste heat and tail water. The two companies had previously already worked together on the 5oo-kW ORC power plant in Lahendong in South Sulawesi.
The decision-makers from the companies aim to utilize waste heat and tail water to double the installed power generation capacities of PGE’s geothermal facilities in a manner that is efficient and low-cost. The total planning portfolio for waste heat utilization is 210 MW. PGE is planning is to announce tenders related to this initiative within the year.
Exploration at Seulawah Agam
PT PGE has also signed an agreement with PT Pembangunan Aceh (PEMA) for the geothermal exploration of the Seulawah Agam prospect in the Aceh region in Sumatra. The Geothermal Working Area (WKP) has a potential capacity of 2 x 55 MW.
“This activity is expected to be an investment opportunity for the development of Aceh in the future. This is a process that has been going on for a long time, and Alhamdulillah it has materialized today,” said Acting Governor of Aceh Achman Marzuki.
“The process took a long time. The WKP was established in 2007, and the auction was held in 2011 with PT PGE eventually being declared the winner. In 2022, the Acting Governor Mr. Achmad Marzuki again wrote to the Minister of Energy and Mineral Resources to accelerate the plan,” recounted the Head of the ESDM Service, Mahdinur.
During the same event, PT PGE also confirmed a collaboration with Chevron New Energy International to develop the South Sumatra Grid Resources Confirmation of 900 MW, and another cooperation with PT Schlumberger Geophysics Nusantara to increase the use of steam recovery method technology.
