Lahendong IV Geothermal Power Plant, Indonesia | 80 MW Facility

Lahendong IV is a geothermal power plant located in Indonesia, with a capacity of 80 megawatts. The facility is jointly owned by PLN and Pertamina Geothermal Energy, reflecting a partnership between the state utility and a national energy company. As a geothermal plant, it harnesses the volcanic heat of the Indonesian archipelago to generate electricity. The plant operates under Indonesia's regulatory framework for geothermal energy, which includes the Geothermal Law No. 21/2014 and supporting regulations. Geothermal power is a key component of Indonesia's strategy to increase renewable energy share, given the country's vast geothermal potential. The 80 MW capacity places Lahendong IV in the medium-scale range for geothermal plants globally. Lahendong IV plays a significant role in the local grid, providing baseload renewable power. Geothermal plants have low emissions compared to fossil fuel plants, contributing to reduced carbon footprint. The facility supports energy security and sustainable development in the region, aligning with Indonesia's goals for clean energy transition.

Geothermal power generation like Lahendong IV has a low environmental footprint compared to fossil fuel plants, with minimal CO2, SOx, and NOx emissions. However, geothermal operations can release trace amounts of hydrogen sulfide and other gases. The plant's location in a volcanic region requires careful management of geothermal fluids to prevent land subsidence and induced seismicity. Proximity to populated areas is a consideration for noise and visual impact, but overall, geothermal is considered a clean energy source.
