Sulzer Serving Energy Transition and Security in Indonesia

The agreement will support energy security and transition for the country’s growing population. As a clean and renewable resource, geothermal energy production reduces reliance on conventional energy sources, lowers greenhouse gas emissions and provides a stable and sustainable source of energy. Sulzer will provide strategic maintenance support to all of PGE’s geothermal power plants to ensure their combined capacity of 330 MW – enough to power approximately 620,000 homes in a sustainable way.

The news comes as the nation continues to intensify its efforts towards achieving its 2060 net-zero emissions target, including the increase of renewable energy production and transitioning away from conventional energy sources. Located on the volcanically active Pacific Ring of Fire, Indonesia has vastly untapped geothermal energy reserves. PGE is playing a pivotal role in realizing this potential with a production capacity reaching 672.5 MW across the country. PGE’s plants are critical base loaders for the Indonesian power grid, providing essential production uptime and equipment reliability for a consistent and sustainable power supply.
Under the agreement, Sulzer’s scope of services will include repair technology, outage optimization, overhauls, rotor life extensions and technical advisory services to help PGE achieve its power capacity and supply targets.

Long-standing partnership
President Director of Sulzer Services (Indonesia) Joko Sutopo said: “This agreement is a testament to our long-standing partnership with PGE, showcasing our proven track record and PGE’s trust in our capabilities and commitment to service excellence. With increasing electricity demand driven by industrial growth and rural electrification programmes in the region, we are proud to support PGE in making energy transition a reality. Our goal is to ensure PGE remains a reliable power source for the communities and businesses they serve.”

PGE’s Chief Executive Officer Julfi Hadi added: “As a pioneer in advancing renewable energy in the region, our collaboration with Sulzer underscores our commitment to expanding geothermal energy to support Indonesia’s decarbonization goals and improve energy security. Through this partnership, we also aim to enhance operational excellence by integrating innovative solutions and best practices that increase efficiency, reliability, and sustainability across our geothermal operations. By continuously optimising our processes and leveraging cutting-edge technology, PGE is well-positioned to lead the way in providing clean energy while maintaining world-class standards in operational performance.”

“Equipment reliability is critical to the success of our plants, and in Sulzer, we have found a partner that champions innovation in services with multiple technological differentiators. Together, we will leverage our solutions and collective expertise to ensure the optimal performance and reliability of our geothermal power plants.”
