PLTU Priok 3 & 4: Coal Power Plant in Jakarta, Indonesia

PLTU Priok 3 & 4 is a coal-fired power plant located in the Priok area of Jakarta, Indonesia. With a capacity of 100 MW, it is a relatively small-scale facility within the Indonesian power generation sector, which relies heavily on coal for baseload electricity. The plant is owned and operated by PT. Indonesia Power, a subsidiary of the state-owned electricity company PLN. The plant operates under Indonesia's national environmental regulations, which include emission standards for SOx, NOx, and particulates. As a coal-fired plant, it uses subcritical technology typical of older Indonesian units. The facility is part of the Java-Bali power grid, the largest interconnected system in the country, serving a densely populated region. PLTU Priok 3 & 4 plays a role in meeting the electricity demand of Jakarta and surrounding areas. Its location in an industrial and urban zone means it operates in close proximity to populated areas, which influences its environmental management practices. The plant contributes to the local energy supply but faces challenges related to emissions and fuel sourcing.

The plant is situated in the coastal industrial area of Priok, Jakarta, a region with high population density and significant air quality concerns. Coal combustion releases CO2, SOx, NOx, and particulate matter, which can affect local air quality and contribute to regional haze. The facility's age and subcritical technology result in lower efficiency and higher emissions per MWh compared to modern supercritical or CCGT plants. Proximity to residential areas necessitates stringent emission controls and monitoring.
