The high emissions from the coal-powered Adaro plant have sparked controversy

Published: Mar 01, 2024 14:24 (GMT+8)
The environmental impact of the Adaro aluminum plant project has sparked controversy, particularly regarding the high emissions caused by coal-fired electricity. Despite Indonesia's vast hydroelectric potential, long construction cycles have been a driving factor in favor of coal power. However, with the construction of the Mentarang hydroelectric power station, there is potential for a more environmentally friendly power supply for industrial areas in the future, which could have a positive impact on reducing the environmental burden of the Adaro aluminum plant project.

Indonesia's North Kalimantan is in the process of constructing the Adaro aluminum project, with a long-term plan for an annual aluminum production capacity of 1.5 million tons. This project, backed by Indonesia's renowned coal company, the Adaro Energy Group, utilizes coal power and has garnered significant attention from both domestic and international media due to Chinese investment and operation involvement.

Since its announcement, the project has been mired in controversy, with the primary concerns revolving around its economic viability and the high CO2 emissions resulting from coal-powered operations, drawing widespread criticism from the public.

According to a recent study by IEEFA, the Adaro aluminum project's Phase One (500,000 tons/year) utilizing coal power and constructing a thermal power plant could result in CO2 emissions equivalent to nearly 1% of Indonesia's total emissions in 2021.

Another issue is Indonesia's reliance on large-scale thermal power plants fueled by coal. This reliance stems from the lengthy construction period for hydroelectric projects in Indonesia. The largest hydroelectric plant in Indonesia, the Mentarang Hydroelectric Power Station with a capacity of 1.37 gigawatts (GW), broke ground in March 2023 and is scheduled to enter the construction phase in the first quarter of 2024, with operation expected by 2030. This plant will provide eco-friendly power to North Kalimantan's industrial zone and meet the electricity demands of the Adaro aluminum project's Phase Three (with an annual capacity of 500,000 tons).

Rio Tinto Secures Bell Bay Smelter Operations Through End-2031
Rio Tinto announced on October 1 that it had reached agreements with the Tasmanian Government, the Australian Commonwealth Government and Hydro Tasmania to extend electricity supply to the Bell Bay aluminium smelter through the end of 2031. The two governments will also provide a combined A$200 million support package over five years, contributing A$100 million each. Commercial terms of the power agreement were not disclosed. Bell Bay produces around 190,000 tonnes of primary aluminium annually, while its existing electricity contract was due to expire at the end of 2026. The agreement removes the smelter’s immediate operational uncertainty. Bell Bay is the third major Australian aluminium smelter to receive government-backed support in 2026, following Boyne and Tomago, highlighting continued pressure from high electricity costs and international competition.
