Jakarta—PT Barito Renewables Energy Tbk (BREN), through its subsidiary Star Geothermal Energy, announced on Thursday, September 19, that it will significantly increase the installed capacity of its Geothermal Power Plant (PLTP).
Barito Renewables Energy President Director Hendra Soetjipto Tan said that the strategic initiative aims to increase the capacity of Star Energy Geothermal through retrofitting projects and adding new capacity. This will not only increase the capacity of various geothermal units operated by Star Energy but also support Indonesia’s efforts to achieve the net zero emission target.
“By retrofitting and adding capacity to existing plants, we are ensuring a sustainable and efficient future for clean energy in the country,” Hendra said. He explained that the partnership increases capacity and drives technological advancements in geothermal energy, putting the company at the forefront of the industry.
The various initiatives announced at the conference are projected to increase Star Energy Geothermal’s installed capacity by 102.6 megawatts (MW). The total investment is estimated at USD346 million.
The initiative to add new power plants or expand will consist of expanding Salak unit 7 with an additional 40 MW. This project is a joint operation (O) with PT Timas Suplindo and PT Rekayasa Industri. It will add 40 MW to the Salak geothermal field by utilizing the Salak injection rearrangement program.
Second, Wayang Windu Unit 3 will be expanded by an additional 30 MW. PT Inti Karya Persada Teknik is the partner in this project. The expansion will add 30 MW to the Wayang Windu geothermal field, optimizing existing surface facilities to increase total capacity.
At the same time, the capacity of existing units will be increased. First, the retrofit of Wayang Windu Units 1 and 2. The partners in this project are the Consortium of Fuji Electric Co. Ltd. (lead firm) and PT Wasa Mitra Engineering. This retrofit aims to improve the technology and efficiency of Wayang Windu Units 1 and 2, with an increase in total generating capacity of 18.4 MW. This will increase the capacity of each unit to 124.45 MW and further ensure the long-term reliability of the power plant.
Then, with partner PT Fuji Electric Indonesia, retrofit Salak Units 4, 5, and 6. The Salak retrofit project will replace the turbine rotor and diaphragm with the latest design, improve efficiency, and increase the combined capacity of Units 4, 5, and 6 by 7.2 MW.
Third, the Darajat Unit 3 retrofit with partner PT Mitsubishi Power Indonesia. Through technology upgrades, the Darajat Unit 3 retrofit will improve energy efficiency and capacity by 7 MW, increasing total capacity from 122 MW to 129 MW.
The Company also established a laboratory services collaboration, partnering with PT Pertamina Geothermal Energy Tbk. The partnership will focus on geothermal fluid sampling and analysis to improve operational efficiency and compliance with good corporate governance principles.
“The development of these projects will increase capacity from 230.5 MW to 278.9 MW at Wayang Windu, from 381 MW to 428.2 MW at Salak, and from 274.5 MW to 281.5 MW at Darajat,” Hendra said.
He added that the development of these projects is following the terms and conditions of the Joint Operation Contract (KOB), which allows Star Energy Geothermal to increase capacity to 400 MW at Wayang Windu, 495 MW at Salak, and 330 MW at Darajat. (hs)
