Asam-Asam power station, also known as Banjarmasin or Kalselteng-2, is a 260-megawatt (MW) coal-fired power plant in South Kalimantan Province, Indonesia. A 200 MW expansion has been proposed.

Background on Plant

The Asam-Asam power station consists of four units: the two-unit, 130-MW Banjarmasin Asam-Asam-A plant, built in 2000; and the two-unit, 130-MW Kalsel Asam-Asam plant, built in 2013.[2] All four existing units are owned by PLN.

Damage to Plant

In June 2016 the plant suffered damage to its control system that led to blackouts in some areas of South and Central Kalimantan. The problems were blamed on postponement of maintenance due to Ramadan. A team of experts from Japan was working to fix the damage.[3]

Proposed Expansion

PLN is currently planning to add two more 100-MW units, known as the Banjarmasin Asam-Asam-B power station; the two additional units are described in the media at Units 5 & 6 of the Asam-Asam plant or Units 5&6 of Kalselteng-2. The original plan was apparently to build three additional units; this plan was scrapped due to various problems, including investors withdrawing from the project. In May 2013, though, the project was reborn, but now as two rather than three units.[4]

According to an October 2013 report, development of the project "is still waiting for a letter of feasibility of PT PLN (Persero) from the government." The report continued: "Garibaldi Thohir, President Director of Adaro Energy, said the government’s guarantee is needed because even as Independent Power Producer (IPP), South Kalimantan coal power plant is including on Public Private Partnership (PPP) project scheme."[5]

As of January 2015, South Kalimantan government officials were urging PLN to accelerate the expansion project, in order to help prevent blackouts in the area.[6]

In November 2015, it was reported that two units of 100 MW each had been pre-qualified for tender.[7]

In February 2016, the project entered the auction process. The process was considered likely to finish in 2016, but PLN officials stressed that success was not a certainty.[3]

Construction began in July 2017. Commercial operation of Units 5 and 6 is planned for July and October 2020.[8] In February 2020 it was reported that hundreds of construction workers who had been building the expansion had been laid off and that construction was stalled.[9]


On July 31, 2017, ITOCHU Corporation announced that it had concluded an EPC (Engineering, Procurement, and Construction) agreement for the Kalselteng-2 Units 5 & 6 project.[10] The Japan Bank for International Cooperation (JBIC) and MUFG Bank agreed to cofinance the project with approximately US$241 million in loans. JBIC is providing JPY10.1 billion and US$53 million in loans (for a total of approximately US$144 million), and MUFG is providing JPY6.8 billion and US$36 million in loans (for a total of approximately US$97 million). MUFG's portion of the financing is insured by Nippon Export and Investment Insurance.[11][12]

In October 2020 MUFG announced that it was planning to halve its overseas coal investments by 2030 and eliminate them by 2040.[13]
