PT Adaro Energy Indonesia Tbk, formerly known as PT Alamtri Resources Indonesia Tbk following a corporate name change in 2024, is an Indonesian natural-resources and energy company. Historically, the company was best known for producing and selling thermal coal through its mining operations in South Kalimantan, Indonesia, supported by transportation, logistics, and port infrastructure.
Following the 2024 separation of its coal-mining business into PT Adaro Andalan Indonesia Tbk, the company has focused more heavily on non-coal activities. These include renewable energy, mineral processing, water infrastructure, and other sustainable-development and energy-related projects. Its portfolio has included investments in solar power, hydropower, and aluminum processing, along with supporting infrastructure.
The company’s operations and development projects are primarily based in Indonesia, while its products and services have historically supported domestic customers and international markets in the broader Asia-Pacific region. Adaro Energy Indonesia became a publicly listed company on the Indonesia Stock Exchange in 2008, building on the Adaro Group’s earlier coal-mining operations.
