PLTGU Tambak Lorok – 1,034 MW Gas Power Plant in Semarang, Indonesia

PLTGU Tambak Lorok is a gas-fired power plant located in Semarang, Central Java, Indonesia, with a capacity of 1,034 MW. It is owned and operated by PLN - Indonesia Power, the state-owned electricity utility. The plant is a significant asset in the Java-Bali power grid, supplying electricity to a densely populated region. The plant uses natural gas as its primary fuel, which generally results in lower emissions compared to coal-fired plants. It operates under Indonesia's national electricity regulations, which are aligned with the country's commitment to reduce greenhouse gas emissions. The technology employed is likely combined-cycle gas turbine (CCGT), which offers higher efficiency than simple-cycle plants. As a major gas-fired facility, PLTGU Tambak Lorok contributes to Indonesia's energy mix, supporting industrial and residential demand. Its location near the coast facilitates fuel supply via LNG terminals. The plant's operation is crucial for grid stability in Central Java and beyond.

The plant's gas-fired technology produces lower CO2, SOx, and NOx emissions compared to coal plants, but still contributes to local air quality concerns in the Semarang area. Proximity to populated zones requires adherence to Indonesian emission standards. The facility's efficiency and fuel choice reduce its environmental footprint relative to older subcritical plants.
