           MedcoEnergi Reduces Gas Fuel Consumption, Enhances Efficiency and Energy Transition

Jakarta, 13 October 2025 – PT Medco Energi Internasional Tbk (MedcoEnergi) has achieved significant progress
in its Fuel Gas Optimization Program through a series of initiatives across its oil and gas assets. These
achievements strengthen operational efficiency, support Indonesia’s energy transition, and deliver carbon emission
reductions.

A key initiative was the optimization of the Waste Heat Boiler (WHB) operating mode at the Grissik field, Corridor
Block, South Sumatra. By utilizing heat from the combustion of waste gas from production process to produce
steam, operations became more efficient and environmentally friendly, cutting emissions by approximately 19,000
tCO₂e annually.

In Natuna Offshore, the optimization of the Terubuk–Belida facility allowed production to flow without compressors,
lowering emissions by around 24,000 tCO₂e each year. For Onshore assets, efficiency improvements were
achieved through electrification, converting power supply from gas-fueled generators to PLN’s clean electricity grid,
along with optimized turbine and compressor operations.

“Fuel gas efficiency and emission reduction are not only technical targets, they are part of MedcoEnergi’s long-term
sustainability roadmap. Since 2022, our initiatives have cumulatively reduced gas fuel consumption by about 18
MMscfd. These results reflect our commitment to continuous innovation, operational excellence, and responsible
energy development, creating long-term value for stakeholders while reducing our carbon footprint,” said Ronald
Gunawan, Director & Chief Operating Officer of MedcoEnergi.

Looking ahead, MedcoEnergi will continue advancing its sustainability agenda through its medium- and long-term
roadmap, including the adoption of new technologies such as Organic Rankine Cycle, Steam Turbine Generators,
and energy storage systems, reinforcing its role as an adaptive and responsible energy company committed to
Indonesia’s energy security. (***)
