PT Rekayasa Industri (Rekind), through its subsidiary, PT Rekayasa Engineering (RE), officially signed the Notification of Award (NOA) for the Dieng Unit 2 Geothermal Power Plant EPC project under a Joint Operation (JO) scheme with PT Timas Suplindo (Timas).
The signing ceremony took place at the opening of the prestigious 11th Indonesia International Geothermal Convention & Exhibition (IIGCE) 2025 at the Jakarta International Convention Center (JCC), September 17-19, 2025.
The NOA, signed by RE President Director Donal Silitonga and Timas Suplindo President Director Sulianto Entong, was witnessed by the Minister of Energy and Mineral Resources (ESDM) Bahlil Ladadalia, Rekind President Director Triyani Utaminingsih, Rekind Director of Operations & Technology/Development Yusairi, and several other key officials.
With the signing, RE, as part of the JO Team, has full authority to carry out the challenging and strategic EPC work for the Dieng 2 Geothermal Power Plant.
Rekind’s President Director, Triyani Utaminingsih, emphasized that Rekind will fully support its subsidiary, which has been entrusted with overseeing the project. “We are present through our Project Management Team (PMT) function as well as providing exclusive engineering services. Rekind’s presence is not merely symbolic, but a concrete manifestation of our commitment to ensuring this project runs according to targets and meets the highest quality standards,” she said.
As supporting technology, the JO team will partner with Fuji Electric Co., Ltd., a global Japanese company with experience in providing environmentally friendly technology for geothermal power plants.
According to RE’s President Director, Donal Silitonga, the Dieng 2 project presents not only technical challenges but also social ones. Its location in a tourist area requires careful planning. “The power plant is located in an isolated area, making it relatively easy to monitor. However, the 9-10 kilometer pipeline traverses tourist routes and densely populated areas. This is where the social challenges are greatest. Residents, tourists, and local businesses must remain comfortable despite the large project nearby,” explained Donal Silitonga.
Technically, Dieng 2, with a capacity of 55 MW, has quite limited logistics. Road congestion, peak tourist activity on weekends, and potential material distribution bottlenecks require early intervention. “There’s only one solution: well planning. Everything must be planned in detail so that logistical and social challenges can be overcome without compromising the completion target,” he added.
This project will rely on more modern technology than Dieng Unit 1, which still uses older systems. One example is the implementation of special technology to prevent silica buildup in the pipeline, given the high silica content of steam wells in the Dieng area. “With this technology, the reliability of geothermal fluid flow to the plant will be more assured. We want Dieng 2 to not only be a power plant with optimal potential, but also a symbol of Indonesian geothermal innovation in the eyes of the world,” said Donal Silitonga.
