Indonesia’s flagship electric vehicle battery factory, a joint venture between China’s CATL and state-owned Indonesia Battery Corporation (IBC) in Karawang, West Java, has begun operating on a phased basis, government officials said in August. The plant is a key piece of Jakarta’s plan to turn the country’s vast nickel reserves into a domestic battery industry.
Commissioning under way
Ahmad Erani Yustika, secretary-general of the Ministry of Energy and Mineral Resources, confirmed the start of operations to Bloomberg Technoz on 21 August:
“It may still be in stages, but it has started operating.” – Ahmad Erani Yustika, Ministry of Energy and Mineral Resources, to Bloomberg Technoz (translated from Indonesian)
Bloomberg Technoz reported that commissioning was under way and that the factory had been expected to be formally inaugurated by President Prabowo Subianto before Independence Day on 17 August, although the ceremony was still awaiting a date in the president’s schedule. English-language outlet Investortrust described the start as trial runs and quoted Mr Erani as saying construction was effectively complete.
Cells, modules and packs
The plant is run by PT Contemporary Amperex Technology Indonesia Battery (CATIB), a company formed by CATL subsidiary CBL, mining firm Antam and IBC. Speaking to Bisnis.com in June, IBC chief executive Aditya Farhan Arif said CATIB would produce battery cells, modules and complete battery packs, serving both electric vehicles and battery energy storage systems (BESS).
Initial capacity is 6.9 GWh a year, with plans to expand to 15 GWh – more than double – which Bisnis said was targeted for the following year. Mr Aditya signalled that the pace of expansion would depend on the market:
“With batteries, a battery factory really has to wait for demand.” – Aditya Farhan Arif, IBC, to Bisnis.com (translated from Indonesian)
IBC has also said it hopes to export batteries to Europe, kumparan reported in May.
Part of a larger nickel-to-EV chain
According to Investortrust, the Karawang plant represents an investment of about US$1.2 billion and forms part of the wider Indonesia Battery Integration Project, valued at US$5.9–6 billion, which aims to link nickel mining and processing with cell production and recycling. The outlet also quoted President Prabowo setting a goal of large-scale commercial production of Indonesian electric passenger cars by 2028.
Indonesia holds the world’s largest nickel reserves, and nickel-based chemistries such as NMC are central to the government’s industrial strategy. However, many of the most popular EVs now sold in Indonesia use lithium iron phosphate (LFP) batteries, which contain no nickel – one reason why officials are keen to secure a domestic cell supply chain that carmakers will actually use. Whether the Karawang plant’s output ends up in locally assembled cars, energy storage or exports will be closely watched.
What it means for buyers
For now, the start of production at Karawang will not change the price of any EV in a showroom. Over time, however, a domestic source of cells and packs should help carmakers meet Indonesia’s rising local-content requirements – 60% from January 2027 – which determine eligibility for tax incentives. Locally made batteries could also make replacement packs and battery servicing easier and cheaper to obtain, a common concern for Indonesian buyers weighing up an EV’s long-term running costs.
