Located in Southern Sumatra, east of Bandar Lampung, the Ulubelu power plant taps into the nearby Ulubelu geothermal field to generate clean electricity for the Sumatra Interconnected Grid. Heat from the underground geothermal reservoir produces steam which spins a turbine and drives a generator to produce clean and renewable electricity. 

As well as producing clean electricity and reducing greenhouse gas emissions, the Ulubelu geothermal power plant contributes to Indonesia's sustainable development. By investing in the region, the project is creating employment opportunities, which boosts the local economy. As an inexhaustible source of energy, the geothermal power plant also diversifies Indonesia's sources of electricity generation, improving energy security and driving the country towards a low-carbon energy future.
