Pacitan Power Station: 630 MW Coal Power Plant in East Java, Indonesia

Pacitan power station is a coal-fired power plant located in Pacitan Regency, East Java, Indonesia. With a capacity of 630 MW, it is a medium-to-large scale facility within the Indonesian power generation sector. The plant is owned and operated by PT PLN Persero, the state-owned electricity company, and plays a key role in supplying power to the Java-Bali interconnection system. The plant uses coal as its primary fuel, a common choice in Indonesia due to abundant domestic coal reserves. The technology employed is typical for coal plants of this era, likely subcritical or supercritical, though specific details are not publicly available. 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 follow national regulations, which are generally aligned with international best practices but may have less stringent enforcement. Located on the southern coast of Java, the plant's operations are subject to local environmental considerations, including air quality impacts on nearby communities and coastal ecosystems. As part of PLN's generation fleet, Pacitan power station contributes to grid stability and supports economic development in the region. Its continued operation underscores Indonesia's reliance on coal for baseload power, though the sector faces increasing pressure to transition towards cleaner energy sources.

The plant's coal combustion releases CO2, SOx, NOx, and particulate matter, contributing to local air pollution and greenhouse gas emissions. Its coastal location may affect marine ecosystems through cooling water discharge. Proximity to populated areas in East Java necessitates adherence to national ambient air quality standards. The facility's age and technology level influence its emission intensity, with older subcritical units typically having higher emissions per MWh than modern supercritical or ultra-supercritical designs.
