PLTU Sumbar - Teluk Sirih Unit 1: 112 MW Coal Power Plant in West Sumatra, Indonesia

PLTU Sumbar - Teluk Sirih Unit 1 is a coal-fired power plant located in Teluk Sirih, West Sumatra, Indonesia. With a capacity of 112 MW, it is a medium-scale facility within Indonesia's coal-dominated power generation sector, which relies heavily on domestic coal resources. The plant operates under Indonesia's national regulatory framework, including Ministry of Environment and Forestry decrees on emission standards for thermal power plants. As a coal-fired unit, it uses subcritical technology typical of plants built in the early 2000s. The facility is owned by PLN, the state electricity utility, and was constructed by CNTIC. This plant plays a key role in supplying electricity to the West Sumatra region, supporting industrial and residential demand. Its location near the coast facilitates coal transport. The plant's operations contribute to local energy security but also involve emissions management under Indonesian environmental regulations.

The plant's coal combustion produces CO2, SOx, NOx, and particulate matter, with emissions subject to Indonesian ambient air quality standards. Its coastal location may affect marine ecosystems, and proximity to populated areas requires careful dispersion modeling. The facility's age and subcritical technology result in lower efficiency compared to modern supercritical plants, leading to higher per-MWh emissions.
