PT Pertamina Geothermal Energy kicks off the EPCC for a 500 kW binary cycle ORC unit at the Lahendong geothermal field in North Sulawesi, Indonesia.

State-owned PT Pertamina Geothermal Energy (PGE) has kicked off a new geothermal development at the Lahendong geothermal field in Tomohon, North Sulawesi, Indonesia.

The Engineering, Procurement, Construction and Commissioning (EPCC) procurement tender process for production facilities and the plant (PLTP) was started on July 1, 2021 and will see the construction of a 500 kW Binary Organic Rankine Cycle Geothermal Power Plant.

PGE Operations Director, Eko Agung Bramantyo, emphasized that PGE is ready to operate a Geothermal Power Plant (PLTP) to support Green Energy and Cost Saving for OPEX as the implementation of Pertamina’s Internal EBT strategic project milestones and the total installed power capacity of other EBT.

“Although the COVID-19 pandemic has not dampened the spirit of innovation and dedication of Pertamina officers in developing Indonesia’s geothermal energy. This is a tangible manifestation of PGE’s commitment to utilize the potential of domestic energy that is environmentally friendly, especially geothermal energy because it is only renewable,” explained Eko Agung.

It is stated that the installation of the Binary power plant with a capacity of 1×500 kW Net is planned to use R1233zd(E) working fluid, which is a non-flammable and environmentally friendly refrigerant. The project is targeted to be 100% implemented and ready to operate in December 2021.

Eko Agung said that this project was carried out using the Quick Win scheme to achieve the Fast Delivery Project. This scheme was carried out by PGE to deal with project implementation in the midst of a pandemic condition in order to remain On Time, On Budget, On Scope, On Revenue (OTOBOSOR).

As is known, Indonesia is currently in the second rank of geothermal development in the world with a total installed capacity of 2,133 MW. Meanwhile, Pertamina has more than 35 years of experience in operating geothermal fields, which are now managed by PGE.

The contribution of the PGE Working Area is 88% of the total installed geothermal capacity in Indonesia, which consists of 672 MW which is operated independently and 1,205 MW which is carried out through joint operation contracts.

Of the 672 MW operated by PGE alone, it was generated from 6 areas namely Lahendong Area – North Sulawesi with an installed capacity of 120 MW, Kamojang Area – West Java with an installed capacity of 235 MW, Ulubelu Area – Lampung with an installed capacity of 220 MW, Karaha Area – West Java with an installed capacity of 30 MW, Lumut Balai Area – South Sumatra with an installed capacity of 55 MW and Sibayak Area – North Sumatra with an installed capacity of 12 MW.
