Jakarta, December 1, 2025 – PT Pertamina Geothermal Energy Tbk (PGE) (IDX: PGEO) is strengthening its position as a leading innovator in the Indonesian geothermal industry through the development of Flow2Max®. This technology enables real-time measurement of geothermal fluid flow, developed by PGE as an innovation to increase efficiency, reduce downtime, and strengthen the sustainability of reservoir management. The introduction of Flow2Max® marks a significant milestone in enhancing Indonesia's technical capabilities in the global geothermal industry.
Flow2Max® is a two-phase flow meter technology that enables operators to monitor fluid flow in real time, enabling PGE to more accurately evaluate performance and predict the productivity of production wells. The implementation of Flow2Max® also strengthens reservoir management and optimization in each geothermal field, including helping to detect potential technical issues early in the well.
Ahmad Yani, Director of Operations at PT Pertamina Geothermal Energy Tbk, emphasized that the development of this technology and innovation stems from PGE's belief that geothermal energy has enormous potential to become a reliable, sustainable, and environmentally friendly energy source.
"More than just a technology that supports the productivity of geothermal operations, Flow2Max® also represents PGE's innovative contribution to the nation. Developed by our officers, this sustainable innovation is key to maintaining the sustainability of reserves through tighter and more accurate monitoring of reservoir conditions. We are proud that the benefits of Flow2Max® are not only felt by PGE but also have a positive impact on the national and global geothermal industry. Through ongoing collaboration with officers, private partners, and the government, PGE is optimistic about realizing our vision of becoming a world-class green energy company that promotes clean and sustainable energy development," he said.
This innovation was developed from doctoral research by PT Pertamina Geothermal Energy Tbk's Manager of Production and Operation Excellence, Mohamad Husni Mubarok, Ph.D., while studying at the University of Auckland.
Edwil Suzandi, Director of Exploration and Development at PT Pertamina Geothermal Energy Tbk, emphasized that Flow2Max® is not only a technological innovation but also a means of strengthening the national geothermal industry ecosystem.
“Flow2Max® is proof that Indonesia is capable of developing world-class geothermal technology. Supported by six patents obtained in Indonesia, the United States, New Zealand, Iceland, the Philippines, and Turkey, this Indonesian innovation demonstrates global competitiveness. Furthermore, Flow2Max® has been installed in five production wells in the PGE Lahendong Area after undergoing a prototype stage and a series of performance tests. Furthermore, we aim to implement this technology across all operational areas within the next three years,” explained Edwil Suzandi.
Flow2Max® works by installing a specially designed orifice plate on a two-phase pipe to create measurable disturbances in the fluid flow. The resulting data is then processed by a flow computer using PGE's exclusive algorithm, the Mubarok Correlation. This information is then securely transmitted via fiber optic, wireless networks (LoRa), and Internet of Things (IoT) systems to the control room and web-based dashboard. With features such as real-time measurement, secure and encrypted transmission, the widest measurement range, and easy installation, Flow2Max®? provides easy integration across various operational assets.
Strategic technology aligned with the national energy transition commitment
Flow2Max®? affirms PGE's position as a leader in geothermal innovation in Indonesia and a driving force for increased clean energy production. This technology also strengthens PGE's efforts to create new revenue sources through technology commercialization and the development of a geothermal manufacturing and services ecosystem.
This effort aligns with the national energy mix transformation agenda outlined in the Electricity Supply Business Plan (RUPTL), which targets a 76% share of New and Renewable Energy (NRE) generation by 2025-2034. Of this target, geothermal energy is projected to contribute 5.2 GW.
The development of Flow2Max®? was carried out through synergy with Ecolab International Indonesia (Ecolab) which was marked by the signing of a Memorandum of Understanding (MoU) on August 15, 2024. The results of this collaboration will be officially introduced to the public on Tuesday, December 2, 2025. In the future, Flow2Max®? also has the potential to be adapted to the oil and gas sector, opening up wider commercialization opportunities.
