The role of coal in providing national energy has already increased nowadays, and still taking an important subject. Government obligation to support added value is not really encourage industry player to applied technology energy that has been developed widenly in South Africa, China and others developing country. The scope of this research is technology energy for coal diversification, such as Coal Upgrading, Coal Gasification, Coal Liquefaction, Coal Water Mixture, and applied Coal Bed Methane Technology that extract gas methane from the pore of coal. The purpose of this research is to estimate coal resources, quality range and to select technology energy that can be potentially develop in PT. Bukit Asam (Persero), Tbk. Coal Resources and coal quality in each mining licences area becomes the basic strength for developing technology energy as part of SWOT Analysis. Based on the SWOT Analysis from 5 technology energy then the scope limited into 3 highest technology energy that is Coal Gasification, Coal Liquefaction and Coal Bed Methane as the most potential technology energy to develop in PT. Bukit Asam (Persero), Tbk.

Current global economic conditions have made the coal prices become uncertain. PT Bukit Asam (PTBA) has taken corporate action by improving operational efficiency, cost control, develop coal diversification product and also optimizationin the mining operation. One of the operational efficiency programs for cost control in mining operation system is the Electrification Program. This program changed mining operations previously dominated by fuel-based mining system transformed into an electricity-based mining system for an electricshovel continue with the conventional truck. Implementation of Mining Systems with electric-based mining equipment divided into several stages for short-term and long-term targets. Electrification program consist of 7 Units Electric Shovel (PC3000-6E) and 40 Units Rigid DT (Belaz75135) with target20 Million BCM in 2017 located inBanko West Mine. PTBA through the electrification program has succeeded in reducing energy consumption by 333,861.74 GJoule/Years and reducing greenhouse gas emissions by 15,058.49 Ton CO2e/Year. Electrification program has successfully contributed for environmental sustainability by reducing energy consumption and greenhouse gas emissions in accordance with the vision of PTBA into a world-class energy company that cares about the environment.
