PLTU Tarahan #1 & 2: Coal Power Plant in Lampung, Indonesia

PLTU Tarahan #1 & 2 is a coal-fired power generation facility located in Tarahan, Lampung, Indonesia. With a total capacity of 200 megawatts, it is a medium-scale plant within the Indonesian power sector. The plant is owned and operated by Indonesia Power, a subsidiary of PLN, and plays a key role in supplying electricity to the Sumatra interconnection system. The plant utilizes coal as its primary fuel, a common choice in Indonesia due to abundant domestic coal reserves. The technology employed is typical for plants of this era, likely using subcritical boiler technology. Indonesia's power generation sector is regulated by the Ministry of Energy and Mineral Resources, with environmental oversight from the Ministry of Environment and Forestry. Emission standards for coal plants are governed by national regulations, including limits on SOx, NOx, and particulates. Located near the coast of southern Sumatra, the plant's operations are subject to local environmental considerations, including air quality management in the surrounding region. As part of the national grid, PLTU Tarahan contributes to the reliability of electricity supply for industrial and residential consumers in Lampung and beyond. The plant's continued operation supports Indonesia's economic development while balancing environmental compliance with national energy needs.

The plant's coal combustion produces CO2, SOx, NOx, and particulate emissions, contributing to local and regional air quality impacts. Its location near populated areas in Lampung necessitates adherence to Indonesian emission standards. The use of subcritical technology may result in lower efficiency and higher emissions per MWh compared to modern supercritical plants. Proximity to coastal ecosystems also requires careful management of water discharge and ash disposal.
