Ulubelu Unit 3 & 4 Geothermal Power Plant (2 × 58.8 MW)

The Project involves the development of well clusters, Steamfield Above Ground System (SAGS) and a power plant. The steam extracted from the geothermal wells will power a geothermal power station with an output capacity of 110 MW, made up of the two 55MW units, referred to as Units 3&4. Ulubelu Unit 3 & 4 are part of the Ulubelu Geothermal Power Plant located in the Lampung province of Sumatra, Indonesia. The Ulubelu geothermal field is one of Indonesia’s significant geothermal energy sources, contributing to the country’s efforts to diversify its energy mix and reduce reliance on fossil fuels.
