PLTU Tonasa II (Boiler Turbine Generator) - Coal Power Plant in Indonesia

PLTU Tonasa II (Boiler Turbine Generator) is a coal-fired power plant located in Indonesia, specifically in the South Sulawesi region near the town of Tonasa. With a capacity of 70 MW, it is a medium-scale facility within the Indonesian power generation sector, primarily serving the energy needs of the cement manufacturing operations of its owner, PT. Semen Gresik Tbk/PT. Semen Indonesia. The plant operates on coal as its primary fuel, a common choice for base-load power in Indonesia due to the country's abundant coal reserves. Coal plants of this size typically employ subcritical or supercritical boiler technology. The facility is subject to Indonesian national emission standards, which regulate SOx, NOx, and particulate matter, and may also align with broader ASEAN environmental frameworks. As a captive power plant integrated with a cement plant, PLTU Tonasa II plays a critical role in ensuring reliable electricity supply for industrial processes. Its location in South Sulawesi contributes to the region's energy security and supports local economic development. The plant's environmental impact is managed through compliance with national regulations, though coal combustion inherently involves CO2 emissions and other pollutants.

The plant is situated in South Sulawesi, a region with tropical climate and significant industrial activity. Coal combustion releases CO2, SOx, NOx, and particulate matter, which can affect local air quality. Proximity to populated areas and agricultural land may necessitate stringent emission controls. Indonesia's regulatory framework for coal plants includes ambient air quality standards and emission limits, though enforcement varies. The plant's capacity of 70 MW places it in a moderate scale, with corresponding environmental footprint.
