During a visit to the Sorik Marapi geothermal plant, Director of Geothermal Directorate General of EBTKE, Ida Nuryatin Finahari lauded the fast development of the plant.

The development of the Sorik Marapi geothermal power plant (PLTP) with a total capacity of 240 MW is one of the national strategic projects and is part of the 35,000 MW Program and the 10,000 MW Phase II FTP Program, so the Directorate General of New, Renewable Energy, and Energy Conservation (EBTKE) of Indonesia’s Ministry of Energy and Mines (EDSM).

PT. Sorik Marapi Geothermal Power (PT. SMGP) as the developer has succeeded in connecting Unit I to 45 MW and targeting in 2020 connecting Unit II of the PLTP Sorik Marapi at 45 MW on the 150 kV network of PT. PLN. In addition, PT. SGMP also continues to develop projects through drilling activities to obtain maximum results according to the potential of existing resources.

“I really appreciate the development that has been achieved by PT. SMGP in the last 4 (four) years was particularly successful in connecting Units 1 to 45 MW to the PT network. PLN. I hope that the Sorik Marapi PLTP Unit 2 can be connected in accordance with the schedule and of course it increases the energy mix in Indonesia “said Director of Geothermal Directorate General of EBTKE, Ida Nuryatin Finahari while verifying the progress of the development and achievement of Sorik Marapi PLTP COD Unit 1 (1×42, 3 MW) and the Progress of developing Unit II (1×45 MW) in Mandailing Natal Regency, North Sumatra Province earlier this month.

This visit is part of the supervision activities carried out by the Directorate General of EBTKE on all geothermal power plants that will be connected in 2020. Field visits will continue on the PLTP projects planned for COD in 2020, namely the Rantau Dedap Unit 1 PLTP project (90 MW), West Sumatra and PLTP Sokoria Units 1 & 2 (2 x 5 MW), East Nusa Tenggara.

The Sorik Marapi PLTP project is considered to be very fast in its construction time with an economically competitive project price. The rapid development of the Sorik Marapi PLTP project has proven to be able to reduce the BPP of the Northern Sumatra System Generation. With the inclusion of Unit I and Unit II based on the realization of the Cost of Supply (BPP) of Generating in the North Sumatra System in December 2019 (Rp 1,436, – per kWh), it will reduce the local BPP by around Rp. 6.27 per kWh so that the potential savings on the difference in the Cost of Supply (BPP) for the generation in the Northern Sumatra System is around Rp 129 billion per year.

PT SMGP, whose majority share (95%) is owned by KS Orka Renewables Pte Ltd, a Singapore-based geothermal developer and operator, started the project in mid-2016. In the past three and a half years, drilling of 23 wells on 6 sites has been completed. Drilling and connecting Units 1 to 45 MW at the end of 2019, making the Sorik Marapi geothermal plant the fastest geothermal project based on the duration from the first well drilling (15 October 2016) to operation (COD 1 October 2020) for unit I. The next development target is the Unit 2 45 MW is targeted to operate by the end of 2020, Unit 3 50 MW by the end of 2021, Unit 4 50 MW by the end of 2022 and Unit 5 50 MW to be operational by the end of 2023.

“I also encourage PT. PGE, PLN, and other developers can accelerate the development of their respective PLTP projects so that COD can be in accordance with the targets that have been set “, concluded Ida. Until the end of 2019, Indonesia has an installed geothermal power generation capacity of 2,133 MW, ranked second in the world below the United States. This figure will still increase along with the development of the geothermal industry in Indonesia, given the potential of geothermal energy in Indonesia which is still not fully developed. The development of new and renewable energy is a priority program for the Government of Indonesia to increase the energy mix and reduce dependence on fossil energy and unsustainable energy.
