Project-level captive use details

  • Captive industry use (heat or power): nickel, other metals & mining


The plant is a joint project between PT Tambang Batubara Bukit Asam (PTBA) and PT Aneka Tambang (ANTM) to power ANTM's new ferronickel plant in Tanjung Buli, East Halmahera, North Maluku.[1][2] In March 2019, PTBA and ANTM stated that the project would be 3 x 60 MW and is scheduled for completion in 2023.[3] In October 2019, PTBA announced that it was investing Rp 2.59 trillion (US$185 million) in the project, now described as a 2 x 45 MW plant.[4] In February 2020 a feasibility study for the project was completed.[5] In June 2020 a spokesman for PTBA said the company was waiting for guidance from MIND ID, the Indonesian mining holding company, before continuing with the project.[6]

As of June 2021, the ferronickel plant was expected to begin operating by the end of 2021. Power for the refining process would initially be supplied by PLN. PTBA is also constructing a diesel-fired generator on-site with capacity of 3 x 18 MW, which was expected to be completed by the end of Q1 2022. A supervisor for the project stated that he hoped the coal-fired power station would be operating three years after the diesel-fired generator came online, which suggests a target completion date of 2025 for the coal-fired units.[7][8]

In the RUPTL for 2021-2030, the proposal appeared to be replaced by plans for a gas-fired project.[9] The power station was therefore presumed to be shelved.

In July 2023, the project was referenced as East Halmahera gas power plant.[10]

In December 2023, with no news suggesting that the proposal would move forward as a coal-fired power station in more than two years, the coal units were presumed to be cancelled.


In 2011, a financing agreement for the entire ferronickel processing plant, including the power station, was closed. Bank Mandiri, PT Bank Rakyat, Standard Chartered, and Sumitomo Mitsui Banking Corporation agreed to provide US$650 million in loans to the project.[11][12]

In 2015, PT Aneka Tambang announced that it would use the proceeds of its planned rights issue worth US$376.2 million to fund its ongoing projects, including the East Halmahera Ferronickel (FeNi) smelter project.[12]
