PLTU Banten 1 - Suralaya unit 8: 625 MW Coal Power Plant in Banten, Indonesia

PLTU Banten 1 - Suralaya unit 8 is a coal-fired power generation facility located in the Banten province of Indonesia, near the coast of the Sunda Strait. With a capacity of 625 MW, it is a medium-to-large scale plant within Indonesia's coal-dominated power sector. The plant is owned and operated by PLN-PT Indonesia Power, a subsidiary of the state-owned electricity company Perusahaan Listrik Negara (PLN). As a coal-fired unit, PLTU Banten 1 - Suralaya unit 8 operates under Indonesia's national environmental regulations, which include emission standards for SOx, NOx, and particulates. The plant uses subcritical technology typical of older coal units in the region. Indonesia's power generation sector relies heavily on coal, and this plant contributes to the Java-Bali grid, which serves the country's most populous region. The plant's location in a coastal industrial area raises considerations for local air quality and marine ecosystems. Its operation supports the reliability of the Java-Bali power system, which is critical for Indonesia's economic activity. The facility's age and technology profile place it within the context of Indonesia's ongoing efforts to balance energy demand with environmental targets.

The plant's coal combustion produces CO2, SOx, NOx, and particulate emissions, contributing to local and regional air quality concerns. Its coastal location near the Sunda Strait may affect marine ecosystems through thermal discharge and potential ash disposal. The facility operates in a region with high population density, increasing exposure to emissions. Indonesia's regulatory framework includes emission standards, but enforcement and monitoring vary.
