Background
In January 2024, Indonesia's AMDAL (environmental impact assessment) database listed an announcement for the development of a new 2 million tons/year aluminum refining plant in Riau Province, Indonesia. The facility would be constructed and operated by PT Tianshan Alumina Indonesia. The announcement included additional supporting facilities, including a captive 160 MW coal-fired power station.
The reference number included for the project was 659693dbad83f.[1] The initial public consultation for the project took place in December 2023.[2] A 2023 Wastewater Quality Compliance document for the refinery project listed a 30 MW condensing steam turbine generator and two 25 MW back pressure steam turbine generators.[3]
As of April 2024, Tianshan Alumina (天山铝业在) had reportedly submitted environmental impact assessment documents for approval, completed a feasibility study report, and entered the design stage.[4] The update did not specifically mention the proposed coal-fired power station.
In July 2024, a technical AMDAL meeting was held to discuss the aluminum refining plant and supporting facilities. The "letter number" was BA.758/PDLUK/P2T/PLA.4.0/B/07/2024.[5]
In August 2024, a coordination meeting for "document assistance" was held. The "letter number" was UN.1286/PDLUK/PAUI/PLA.6.1/08/2024.[6]
In November 2024, Tianshan Alumina reportedly obtained mining rights for three bauxite mines in Indonesia. The mines would provide raw materials for the company's aluminum project in the country[7]
As of February 2025, development of the bauxite smelter project was ongoing.[8]
In April 2025, the project's permits were reportedly "almost complete" (Google translate).[9] Reporting in 2025 referenced general "supporting facilities" rather than the coal-fired power unit specifically.
As of September 2025, progress on the development project had reportedly stalled.[10]
In October 2025, the Ministry of Defense requested 400 hectares of the smelter project land that reportedly overlapped with a military training area to be replaced with new land. The Ministry reportedly planned to conduct a field survey to determine an approved location.[11]
In December 2025, PT Tianshan Alumina Indonesia stated that the smelter development was yet to advance due to the project location issues. The project was reportedly administratively licensed, but relocation was possible.[12] The Lingga Deputy Regent stated that relocating the project could restart the permitting process, but the company was reportedly awaiting a response from the Ministry of Defense.[13]
Financing
As of June 2026, no coal-plant-specific financing had been identified for the proposed 160 MW captive coal-fired power station. Public sources describe PT Tianshan Alumina Indonesia’s broader alumina refinery project as a long-term investment of more than US$1.6 billion, with another 2025 source estimating total investment for the alumina refinery project at US$1.556 billion, but these figures refer to the broader alumina project and supporting facilities rather than disclosed financing for the captive coal unit specifically.[14][15]
