Indonesian coal miner PT Bukit Asam (PTBA) is strengthening its mining and logistics infrastructure to improve supply-chain efficiency and support higher coal transport capacity as it seeks to strengthen its competitiveness in the coal market.

The state-controlled miner is prioritizing its Tanjung Enim-Kramasan logistics project in South Sumatra, which is intended to integrate coal transportation and distribution from its Tanjung Enim mining area more closely with downstream logistics facilities, the company said lately during the Public Expose Live 2026 webinar, as cited by local media.

The project was about 93% complete, PTBA Finance and Risk Management Director Una Lindasari said.

PTBA is also accelerating development of a Coal Handling Facility (CHF) and Train Loading Station (TLS) 6-7 along the Tanjung Enim-Kramasan rail route, with the facilities designed to improve coal loading capacity and strengthen the integration of its logistics chain.

To support the projects, PTBA has secured a Rp3.56 trillion ($202 million) senior term loan facility through a term sheet with Indonesia's state-owned banks, known as Himbara, the company said.

The infrastructure investment is aimed not only at increasing coal transport and loading capacity but also at reducing inefficiencies across the supply chain, PTBA said.

PTBA said the Tanjung Enim-Kramasan project and the CHF and TLS 6-7 facilities would provide a stronger logistics system to support customer requirements through higher transport and distribution capacity.

The investment comes as PTBA seeks to expand coal production and sales while improving its logistics capability. The company has set a 2026 coal production and purchase target of 49.55 million tonnes (Mt), up from 47.19 Mt in 2025, while its sales target is 49.51 Mt, compared with 45.43 Mt last year.

The miner's logistics expansion is particularly important because transportation capacity has historically been a constraint on coal production growth at Tanjung Enim. The company has been developing additional rail and handling infrastructure to connect its mines with ports and other distribution points.

PTBA reported 19.45 Mt of coal production and 21.10 Mt of sales in the first half of 2026, according to its latest operational update. Exports rose 5% year on year to 10.33 Mt, while domestic sales stood at 10.77 Mt.

The company has said its stronger logistics infrastructure will support its longer-term strategy of maintaining growth in its core coal business while developing new businesses, including downstream coal processing and renewable energy.

PTBA expects the logistics projects to contribute to a more integrated supply chain and help it maintain growth while supporting Indonesia's energy security and wider economy.
