PLTU Cilacap 1 & 2: 600 MW Coal Power Plant in Cilacap, Indonesia

PLTU Cilacap 1 & 2 is a coal-fired power plant located in Cilacap, Central Java, Indonesia. With a capacity of 600 MW, it is a medium-to-large scale facility within Indonesia's power generation sector, which relies heavily on coal for baseload electricity. The plant is owned and operated by PT. Sumber Segara Primadaya, a subsidiary of PT. Sumber Energi Andalan Tbk. The plant operates under Indonesia's national regulatory framework, which includes emission standards set by the Ministry of Environment and Forestry. As a coal-fired plant, it employs subcritical technology typical of older Indonesian coal plants. The facility's location on the southern coast of Java provides access to coal imports and cooling water from the Indian Ocean. PLTU Cilacap 1 & 2 plays a critical role in supplying electricity to the Java-Bali grid, the largest interconnected power system in Indonesia. Its output supports industrial and residential demand in Central Java and beyond. The plant's coal consumption contributes to Indonesia's significant CO2 emissions from the power sector, but it remains a key asset for energy security in the region.

The plant's coal combustion releases CO2, SOx, NOx, and particulate matter, contributing to local air quality concerns in Cilacap, a densely populated industrial area. Proximity to the coast may affect marine ecosystems through thermal discharge and ash disposal. Indonesia's reliance on coal for over 60% of its electricity generation means plants like this are significant sources of greenhouse gas emissions, though national policies aim to increase renewable energy share.
