JAKARTA (RambuEnergy.com) – Indonesia state owned energy company PT Pertamina said its subsidiary PT Pertamina Geothermal Energy (PGE) installed capacity is expected to increase by 14% per annum in between 2017 to 2021, a company official said.

He said PGE will step up its efforts to explore and develop the existing geothermal energy projects. Some of the geothermal power plants will begin commercial operation this year and next year.

PGE produces steam from its geothermal well and sell to other parties, including PLN to generate power as the case of Kamojang Power Plant Unit 1 and 2. In other case it produces steam and develop its owned geothermal power plants.

Syamsu said in 2017, Pertamina targets to operate two new geothermal power plants, namely PLTP Ulubelu Unit 4 with capacity of 55 MW and PLTP Karaha Unit 1 with capacity of 30 MW. This will raise PGE’s geothermal energy installed capacity to 617 MW by the end of 2017.

PGE is also exploring four geothermal working areas (WKs), namely Selulawah, Bukit Daun, Margabayur and Lawu.

The latest geothermal plant of the company is PLTP Lahendong Unit 6, which began commercial operation on Dec. 9, 2016 with installed capacity of 20 MW. In July 2016, it operated PLTP Ulubelu Unit 3 with capacity of 55 MW.

The other existing geothermal plants are PLTP Kamojang 235 MW, PLTP Lahendong 100 MW, PLTP Ulubelu 165 MW and PLTP Sibayak 12 MW.
