Darajat Power Station

The Darajat Geothermal Power Station is a field complex comprising 3 geothermal power plants situated in District Pasirwangi, Garut, West Java, roughly 150 kilometres (93 mi) south-east of Jakarta. The complex is in the Mt Kendang area, a volcanic region approximately 2 km above sea level. The field supplies dry steam, one of few such fields worldwide.^[1]

In December 1984, the now-defunct Chevron-owned American Overseas Petroleum Ltd. (Amoseas) signed a contract with Pertamina and PLN to build geothermal power plants totaling 330 MW in capacity within a 56,650 hectare region in Darajat, West Java. Amoseas would provide the steam, while PLN would operate the plant; of the three existing plants, Chevron owned the two larger capacity plants, PLN owned only the first. The first such plant, rated at 55 MW, began operations in November 1994.^[1]

Construction of the second plant commenced in 1997, but the government suspended construction shortly afterwards, in 1998, because of a financial crisis. The plant, rated at 94 MW, began operations in April 2000.^[1]

The third plant, rated at 110 MW, began operations in 2007. This capacity was uprated to 121 MW in 2009.^[1]

In April 2017, Chevron's ownership of the plants were bought out by Star Energy Geothermal.^[2]
