Pertamina Geothermal Energy continues work on expanding power generation capacity in the geothermal field of Lahendong, North Sulawesi in Indonesia. The company currently plans an 2x20 MW expansion.

Reported locally, PT Pertamina Geothermal Energy (PGE) in Lahendong Area, North Sulawesi (North Sulawesi) continues to explore new geothermal resources within the Lahendong Geothermal Working Area (WKP), according to General Manager Salvius Patangke.

“To ensure the potential of geothermal energy, Pertamina’s exploration team continues to conduct geological, geochemical and geophysical surveys,” said Salvius in Tomohon. Pertamina continues to explore the possibility of new wells to maintain current production and ensure that production does not decrease.

Currently, PGE develops in the Lahendong area seven and eight units in the Lahendong and Tompaso blocks.  These two units are expected to produce 2×20 MW, bringing the total total capable of producing 8×20 MW.

“We have optimized 6×20 MW, 4×20 MW from the Lahendong block and 2×20 MW from the Tompaso block,” he said.

Salvius, accompanied by PGE Area Operations Manager Lahendong Ahmad Yani and Public Relations of PT PGE Lahendong Dimas Wibisono added that up to now the average produced in each unit is 2×20 MW, unlike in Kamojang and Star Energy in West Java and Lampung which can be optimized up to above 100 MW.

The reason for this is that currently electricity demand in the area is not as big, so Pertamina does not build a bigger electricity system,” he said.

He hopes, in addition to the Lahendong and Tompaso blocks, there are also geothermal energy sources that can be developed economically.
