With ongoing construction work on geothermal projects, Indonesia is confident it will see the addition of 140 MW in geothermal power generation capacity in 2020. Three plants are expected to come online this year, Sorik Marapi Unit II, Sokoria, and Rantau Dedap.

Indonesia’s Ministry of Energy and Mineral Resources (ESDM) is optimistic that the installed geothermal power generation capacity could reach 2,270.7 MW by the end of 2020.

Ida Nuryatin, Director of Geothermal at the Ministry of Energy and Mineral Resources expects an addition of 140 MW this year. “Until the end of last year the geothermal (PLTP)’s operating capacity reached 2,130.8 MW,” she told in an interview with local press.

The three geothermal power plants that entered into operation last year were PLTP Muara Laboh with a capacity of 85 MW, PLTP Sorik Marapi with a capacity of 42.3 MW and PLTP Lumut Balai with a capacity of 55 MW.

She expects that the construction of three geothermal plants will be completed and plants start to operate this year

The first plant is the expected addition of 45 MW of Phase 2 of the Sorik Marapi geothermal power plant. The plant is developed by PT Sorik Marapi Geothermal Power who expects to connect the Sorik Marapi PLTP Unit II of 45 MW to the 150 kV network of PT PLN this year.

The second plant to be aded is the Sokoria geothermal power plant in Ende Regency, Flores Island, East Nusa Tenggara (NTT), which will add 5 MW in capacity from a planned total of 30 MW.

The Sokoria PLTP is one of the national strategic projects and is part of the 35,000 MW Program, as well as the Phase II 10,000 MW Fast Track Program (FTP) undertaken by PT Sokoria Geothermal Indonesia (SGI)

The third geothermal plant that will operate is Rantau Dedap Unit 1 with a capacity of 90 MW in West Sumatra. The investment value for the power plant construction reaches US$ 700 million.

“I encourage PT Pertamina Geothermal Energy (PGE), PT PLN (Persero) and other developers to be able to accelerate the development of their respective PLTP projects so that they can COD (Commercial On Date) in accordance with the targets that have been planned,” she said.

“The development of new and renewable energy is a program that is a priority for the Government of Indonesia to increase the energy mix and reduce dependence on fossil energy and unsustainable energy,” said Ida.

Meanwhile, President & CEO of PT Supreme Energy Muara Laboh Nisriyanto said the development of the Muara Laboh PLTP phase II with a capacity of 65 MW is planned to begin this year and is targeted to be operational in 2024.

“This is still under discussion with the Ministry of Energy and Mineral Resources and PLN. We hope that Phase II can begin this year after licensing and the Power Purchase Agreement is complete,” he said.
