CATL-Antam EV Battery Plant Set to Begin Production Soon

Indonesia's CATL-Antam EV battery plant is expected to begin production soon, according to an update announced on October 29, 2026, following a meeting between Indonesian President Prabowo and the Coordinating Minister for Downstreaming and Energy Transition. The development marks another step in the country's efforts to expand its electric vehicle battery manufacturing capabilities and strengthen its domestic battery industry through downstreaming initiatives.

The project is a joint venture between state-owned PT Aneka Tambang Tbk (Antam) and China's Contemporary Amperex Technology Co., Ltd. (CATL). Its groundbreaking ceremony was led by President Prabowo in 2025. The latest update indicates that the facility is approaching the production stage, although no specific production commencement date or additional operational details were provided in the announcement.

The CATL-Antam project forms part of a broader expansion of Indonesia's electric vehicle battery ecosystem. Other developments include a Hyundai-owned facility and a battery plant inaugurated in Halmahera with Chinese investment. Together, these projects demonstrate the country's growing integration of activities spanning mining, mineral processing and battery cell production as the government advances its downstreaming efforts. The CATL-Antam facility represents another component of this developing industrial structure.

Industry Impact & Outlook

Indonesia's CATL-Antam battery project highlights the importance of connecting domestic mining and mineral processing capabilities with downstream battery manufacturing. Its expected move into production would represent a further development in the country's efforts to integrate different stages of the electric vehicle battery value chain. Alongside the Hyundai-owned facility and the Halmahera plant backed by Chinese investment, the project illustrates the expanding participation of industrial and international partners in Indonesia's battery ecosystem. These developments reflect the government's broader downstreaming strategy, which aims to strengthen the country's position across the battery production chain.
