{{#badges:CoalSwarm|Navbar-Indonesiacoal}}Banten Suralaya power station is a 4,025-megawatt (MW) coal-fired power complex in Banten Province, Indonesia. Development began in 2017 on an expansion that would add Unit 9 (1000 megawatts) and Unit 10 (1000 megawatts).[1] This expansion is also known as Jawa-9 and Jawa-10.


The map below shows the plant, in Pulomerak District, Cilegon City, Banten Province. Units 1-7 are on the southwest side of the complex and Unit 8 is on the northeastern side, with a large open-air coal storage area located between. The site of the Banten Serang power station is just to the northeast of Unit 8.

Background on Plant

Banten Suralaya power station is a 4,025-megawatt (MW) coal-fired power complex consisting of 8 generating units located on the northwest tip of the Indonesian island of Java, close to the city of Cilegon and about 150 km west of the capital city of Jakarta, Indonesia. The complex is owned by PT PLN. In 2017 construction began on Unit 9 (1000MW) and Unit 10 (1000MW) at the same location, under a partnership in which PT PLN Persero has 51% ownership and PT Barito Pacific Tbk has 49%.[1][2]

The power complex was built in four phases:[3][4]

Phase I

  • Unit 1 - 400 MW - 1984
  • Unit 2 - 400 MW - 1985

Phase II

  • Unit 3 - 400 MW - 1988
  • Unit 4 - 400 MW - 1989

Phase III

  • Unit 5 - 600 MW - 1996
  • Unit 6 - 600 MW - 1997
  • Unit 7 - 600 MW - 1997

Phase IV

  • Unit 8 - 625 MW - 2011

PLN also has a major training facility in Merak, several kilometers to the southwest of the Suralaya plant, which uses Suralaya to train PLN workers.[5]

An explosion and fire at the 30-year-old transformer of Unit 4 in December 2013 caused widespread power failures in the area.[6][7]

Coal source

The power station receives coal through its attached Suralaya coal terminal, also owned by PLN. Coal comes from Bukit Asam Coal Mining operations in South Sumatra.[8]

Proposed Units 9 & 10: 1000 MW

In October 2016 PLN announced that it would build two additional Units at the plant and that construction would take three years.[9] In September 2017 PLN President Director of Indonesia Power Sri Peni Inten Cahyani announced that these Units would each produce 1000 MW and would be built with PLN's partner, PT Barito Pacific Tbk, with PLN having 51% ownership.[2] In December 2017 it was reported that construction had begun on Units 9 & 10.[1] In March 2018 the General Manager of the plant estimated that construction of Units 9 & 10 would be complete in 2022.[10]

RUPTL Plans for Jawa-9 & Jawa-10

Jawa-9 and Jawa-10

According to the PT PLN 2016-2025 long range plan (page 147), PLTU Jawa-9 could be developed as an expansion of an IPP which has been in operation, or the construction of new power plants by IPP in Banten province.[11]

According to the PT PLN 2017-2026 plan, both Jawa-9 and Jawa-10 are delayed to 2022 and increased in size from 600 MW to 1000 MW in order to use a more "efficient and environmentally friendly" technology.[12] The plants will be developed either by PLN or as an IPP with alternative locations in Central Java or West Java.[13]

In February 2018 PLN subsidiary Indonesia Power, along with Indonesia petrochemical company PT Barito Pacific, announced they had shortlisted three to four companies for the Engineering, Procurement, and Construction (EPC) contract to develop their Java 9&10 coal-fired power stations, with the selection to be announced by mid-2018. The coal plants are described as ultra supercritical. The 2,000MW project is estimated to cost about US$3.5 billion. Domestic infrastructure financing institutions such as Sarana Multi Infrastruktur are expected to support the power plant, as well as the export credit agency of the selected EPC contractor. The new units are planned to be built next to the existing 4,025MW Banten Suralaya power station.[14]

Jawa-9 does not appear in the 2018-2027 plan, while Jawa-10 appears as a 1,000 MW plant with a completion date of 2024.[13]

In September 2018 it was reported that Doosan Heavy Industries and Construction from South Korea along with Indo Raya Tenaga (IRT) would begin construction of Jawa-9 and Jawa-10 in early 2019.[15]

In May 2019 it was reported that Barito Pacific was still trying to achieve financial close for Jawa-9 and Jawa-10 and hoped to do so by the end of 2019.[16] The long-range plan for 2019-2028 lists a completion date of 2023 for Jawa-9 and 2024 for Jawa-10.[17]

Opposition to plant

As construction began on the Unit 9 & 10 expansion, residents complained about already high levels of air pollution from the plant and damage to the sea and local fishing industry.[1] One resident compared the sight of the nearby plant to a scene from Lord of the Rings.[1]

In November 2018 environmental activists called on the South Korean banks funding the expansion to withdraw their support. The expansion will cost an estimated $1.67 billion and be financed with loans from the Export-Import Bank of Korea (KEXIM), the Korea Development Bank (KDB Bank), and the Korea Trade Insurance Corporation (K-sure).[18]
