PGE’s Lumut Balai Unit 2: The 55 MW Geothermal Breakthrough Powering Indonesia’s Clean Energy Future
PGE’s Lumut Balai Unit 2: A 55 MW Geothermal Triumph Rewriting Indonesia’s Clean Energy Future By: Robert Buluma Indonesia has once again staked its claim as a global geothermal heavyweight. With the successful operationalization of the Lumut Balai Unit 2 Geothermal Power Plant, PT Pertamina Geothermal Energy Tbk (PGE) has delivered a strategic blow in the global race toward clean baseload energy. More than just a 55 MW addition to the country’s energy mix, this project marks a bold step in Indonesia’s ambition to expand its geothermal capacity to 1 gigawatt within the next few years. In a world grappling with climate volatility, unstable energy prices, and growing demand for reliable renewable power, this achievement resonates far beyond Indonesia’s borders. It signals a shift — a declaration that geothermal energy is rapidly maturing, scaling, and proving itself as the backbone of modern clean-energy systems. A Milestone Project in a Region Rich With Geothermal Potential Lumut ...
