Geothermal Project 

The Company’s commitment in that strategic role is formed through acceleration of geothermal energy development in Indonesia. In this case, the Company is consistently building and developing National Geothermal Power Plant (PLTP) projects. 

Ulubelu Unit 3 dan 4. Besides two Geothermal Power Plant units in Ulubelu (unit 1 and 2) that’s been operating, there are also two additional units with total capacity of 2x55 MW. Unit 3 and 4 are currently at Engineering Procurement Construction and Commissioning (EPCC) stage and drilling. The Geothermal Power Plant is planned to be commercially operable in 2016 (unit 3) and 2017 (unit 4).

Lumut Balai Unit 1 dan 2. Lumut Balai Project of Unit 1 and 2 with total capacity of 2x55 MW located at WKP of Lumut Balai and Margabayur, South Sumatera Province. The current status for Unit 1 is at EPCC stage. While Unit 2 is at the stage of infrastructure and drilling preparation. The Geothermal Power Plant is projected to be commercially ready in 2016 (unit 1) and 2018 (unit 2). 

Lumut Balai Unit 3 dan 4. Two additional units of PLTP for Lumut Balai project each have the capacity of 55 MW and still in development process. Currently at the stage of permit. Both units are planned to be commercially operable in 2022.

Lahendong Unit 5 dan 6. Lahendong project at WKP of Lahendong, North Sulawesi Province. Targeted to operate a generator with the capacity of 2x20 MW. Unit 5 is currently at EPCC stage and Unit 6 has done EPCC and drilling. Both units are planned to be commercially operable in 2016 (unit 5) and 2017 (unit 6).

Karaha Unit 1. Located in WKP Karaha Cakrabuana, this project is a continuation of development of the Karaha Bodas Project assigned by the Indonesian Government. The project is located in West Java Province. The Company plans to build a Geothermal Power Plant Unit 1 with a capacity of 1x30 MW. Karaha unit 1 is expected to have its commercial operation in 2017.

Hululais Unit 1 dan 2. Located at WKP of Hululais, about 180 km from Bengkulu city, in Lebong Regency of Bengkulu Province. It has potential capacity of 300 MW. Current status is at the completion of drilling infrastructure and production test. The Company is targeting to build two units of Geothermal Power Plant with the capacity of 2x55MW, planned to operate commercially in 2018.

Sungai Penuh 1 dan 2. Located at WKP of Sungai Penuh of Jambi Province. Geothermal potential is estimated to be 200 MW. Seeing this huge potential, the Company is planning to build two units of Geothermal Power Plant with total capacity of 2x55 MW. Current status is at drilling and production test. Both are expected to operate commercially in 2019.
