Overview
Lahendong (Binary Cycle) is a 20 MW geothermal power plant in Indonesia, operated by BPPT and Pertamina. It contributes to the country's renewable energy capacity.
Lahendong (Binary Cycle) is a geothermal power plant located in Indonesia, with a capacity of 20 megawatts. The facility is owned and operated by BPPT and Pertamina, key players in Indonesia's energy sector. As a binary cycle plant, it utilizes lower-temperature geothermal resources, making it suitable for regions with moderate geothermal activity. The plant operates under Indonesia's regulatory framework for geothermal energy, which includes the Geothermal Law No. 21/2014 and supporting regulations that promote renewable energy development. Indonesia has significant geothermal potential, and plants like Lahendong help diversify the country's energy mix away from fossil fuels. The binary cycle technology is efficient for lower enthalpy resources, reducing environmental impact compared to conventional steam turbines. Lahendong (Binary Cycle) plays a role in providing clean electricity to the local grid, supporting Indonesia's goal of increasing renewable energy share. Geothermal power offers baseload reliability, complementing intermittent sources like solar and wind. The plant's operation contributes to reduced greenhouse gas emissions and local air quality benefits, aligning with national climate commitments.
Environmental context
Geothermal power generation has a relatively low environmental footprint compared to fossil fuels, with minimal CO2, SOx, and NOx emissions. However, it can involve land use for drilling and potential induced seismicity. The Lahendong plant is located in a volcanic region, which provides the heat source but also requires careful management of geothermal fluids to prevent contamination of local water resources. The binary cycle technology minimizes water usage and emissions, as the geothermal fluid is reinjected.
Frequently asked questions
Lahendong (Binary Cycle) is located in Indonesia, specifically in the Lahendong geothermal field on Sulawesi Island. The plant's coordinates are approximately 1.3346° N, 124.8392° E.
Lahendong (Binary Cycle) has a capacity of 20 megawatts (MW), making it a small-scale geothermal power plant.
The plant is owned and operated by BPPT (Agency for the Assessment and Application of Technology) and Pertamina, Indonesia's state-owned oil and gas company.
Lahendong uses binary cycle technology, which is suitable for lower-temperature geothermal resources. It transfers heat from geothermal fluid to a secondary working fluid with a lower boiling point, driving a turbine.
Geothermal plants in Indonesia are regulated under the Geothermal Law No. 21/2014, which governs exploration, exploitation, and power generation. The Ministry of Energy and Mineral Resources oversees permits and environmental compliance.
