By the end of September 2019, KS Orka Renewables brought its first 45 MW plant of its Sorik Marapi geothermal power project in North Sumatra online. With a gen-set setup by Kaishan steam expander and ORC technology, the next units are expected to add additional 45 MW by the end of 2020.

In a release shared with ThinkGeoEnergy, PT Sorik Marapi Geothermal Power (“PT SMGP”) announced that by the end of Q3 2019, the first unit of 45 MW of the Sorik Marapi geothermal project in North Sumatra, Indonesia started commercial operation.

PT SMGP is the license holder for the development and operation of Sorik Marapi?Roburan?Sampuraga Concession Area in Mandailing Natal Regency, North Sumatera Province, Indonesia.

PT Sorik Marapi Geothermal Power is owned by KS Orka Renewables Ltd, a geothermal operator and developer based on Singapore, and PT Supraco Indonesia. PT SMGP received its license under the Geothermal Law on 21 April 2015 and completed its exploration stage in August 2017 and since then the project company moved forward with the development of the first unit of 45 MW. PT SMGP and PT PLN (Persero) have completed the PPA (Power Purchase Agreement) on 27 June 2019 and reached the Effective Date on 9 September 2019.

This project fully utilizes Kaishan Zhejiang Steam Expander and Organic Rankine Cycle technology as power plant, marking it as the first geothermal project in Indonesia that uses modular units. These modular units are able to accommodate geothermal development incrementally, thus it is more adaptable to the regional growth and demands.

The next modular unit of 45 MW is scheduled to connect by the end of 2020.
