SARULLA - PT Perusahaan Listrik Negara (PLN) (Persero) give special attention to the utilisation of Renewable Energy (EBT), especially in order to increase the national electrification ratio. Therefore PLN focus on developing renewable energy power plants as the infrastructure, one of which is Sarulla geothermal power plant (PLTP) in North Tapanuli, North Sumatra.

IPP power plant with a capacity of 3 x 110 MW geothermal power has the potential to be the largest in the world, because of its capacity to develop up to 1,000 MW. Sarulla geothermal power plant developed in two locations: in the project Silangkitang (SIL) with a capacity of 1 × 110 MW (Unit 1) and Namora-I-Langit (NIL) project with a capacity of 2 × 110 MW (Unit 2 and 3). Sarulla Geothermal Power Plant Unit 1 (SIL) has been operating / Commercial Operation Date (COD) on March 18, 2017, while Unit 2 and Unit 3 is planned COD on November 23, 2017, and May 23, 2018.

Ahead of Inauguration Geothermal Power Plant Unit 1 in May, the Minister of Energy and Mineral Resources (MESDM) Ignasius Jonan along with Business Director PLN for Regional Sumatera Amir Rosidin conduct a site visit to review the readiness of the power plant.

In an official press release of PLN (04/03/2017), Ignasius Jonan explained, "We strongly support the of renewable energy development but do not let electric wires are already past the public home, but they are not able to buy electricity. Developers also do not have to be afraid to develop an electricity as much as possible because in this Sumatra PLN will build transmission lines of 275 kV and 500 kV which will supply power to the whole of Sumatra. So we would be very supportive if this geothermal power plants could be 1,000 MW."

Sarulla geothermal power plant projects included in the Electricity Development Acceleration program (Fast Track Program / FTP) 10,000 MW Phase II. Sarulla geothermal power plant operation will improve the reliability of the system in the sub-system of North Sumatra (Sumbagut). This saw the peak load of Sub-system Sumbagut (before Unit 1 COD) reached 2,000 MW with a power capacity of 2,100 MW. Moreover, with the addition of this electric power capacity, then PLN could serve business customers, industry and households. PLN estimates potential customer additions for group R-1900 VA is up to 103,000 subscribers.

"Sarulla geothermal power plant is one of the highly anticipated to strengthen the reliability of North Sumatra. This geothermal power is the answer to the challenge of generating clean and environmentally friendly, "said Amir Rosidin.

Sarulla geothermal power project developed through the Joint Operation Contract (JOC) between Pertamina Geothermal Energy (PGE) and Sarulla Operations Limited (SOL). SOL is a consortium of Medco Power Indonesia, Itochu Corporation (Japan), Kyushu Electric Power Co., Inc. (Japan), and Ormat International, Inc. (USA).
