PT Pertamina Geothermal Energy is planning drilling additional wells to expand its geothermal power generation at Lahendong, Indonesia. The plans see an expansion with two additional power generation units.

The Indonesian government supports the plan of Pertamina Geothermal Energy (PGE) to drill new wells in the Lahendong Geothermal Working Area (WKP). The plan is to drill new wells to supply planned Units 7 and 8 of the Lahendong geothermal power plant complex.

PGE Planning & Engineering Manager Lahendong Apriyansyah Toni explained, the development of new wells was part of the successful operation of units 1 to 6.

“This is a success story of geothermal development in Eastern Indonesia, especially in North Sulawesi. It supplies 20% of electricity in North Sulawesi and Gorontalo,” Apriyansah explained at the PLTP Lahendong Unit 5-6.

Construction preparation, Apriyansah added, will be carried out in cluster A as the development area to start drilling in new wells, namely Units 7 and 8.

We will do the drilling of one well first, after that we will evaluate one well. “From the production test we will find out how much temperature and mass of the fluid so we know how much electricity we can generate,” he said.

For new well drilling activities, PGE Lahendong has budgeted an investment of USD 7 million. Meanwhile, for the construction of facilities and infrastructure in cluster A, PGE Lahendong requires additional funding …. “God willing, the drilling target will be carried out in June 2020,” said Apriyansah.

Meanwhile, Head of the Exploration and Exploitation Supervision Sub-Directorate, Directorate of Geothermal, Directorate General of EBTKE, Ministry of Energy and Mineral Resources, Budi Herdiyanto, said that the government was aware of the development plan. Therefore, the government will fully support what will be planned by PGE Lahendong.

“Support from the government in the form of facilitating how to negotiate with PLN related to the selling price and for licensing, including related to land acquisition, then importing goods,” said Budi.

Peelu is known, WKP Lahendong PGE has six PLTP units, with Units 1 through 4 producing steam and operated by PT Perusahaan Listrik Negara (PLN) with a capacity of 80 MW.

Meanwhile, Unit 5 and Unit 6 are operated solely by PGE, with a total production capacity of 40 MW, which is distributed to PLN.

PGE Lahendong area itself has another role for the people of North Sulawesi, such as being able to electrify up to 92,308  1,300W customer homes and provide electricity access for 369,232 people assuming 4 people in each house.
