Harnessing southern Sumatra's geothermal fields for clean energy
As a country dominated by volcanic geology and situated on the notorious ‘Pacific Ring of Fire’, Indonesia is one of the most seismically active countries in the world. The movement of tectonic plates and churning of molten rock beneath the archipelago triggers around 1,000 tremors a month. While tremors can sometimes be problematic for Indonesia, heat from this seismic activity can be harnessed to the country's advantage; offering a sustainable way to power the country’s homes and industry.

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.
