                    MedcoEnergi Adds 39 MW Capacity to the Batam–Bintan Power System

Batam, 12 November 2025 – PT Medco Energi Internasional Tbk (MedcoEnergi), through its subsidiary
PT Medco Power Indonesia (Medco Power), has commenced the commercial operation (COD) of a 39
MW Add-On Combined Cycle Power Plant (CCPP) in Tanjung Uncang, Batam, on 8 November 2025.

The project, developed by Medco Power’s subsidiary PT Energi Listrik Batam (ELB) under a long-term
power purchase agreement with PT PLN Batam, converts the existing 70 MW open-cycle facility into a
109 MW combined-cycle plant. By utilizing exhaust heat from gas turbines to generate additional power
through a steam turbine, the plant increases efficiency and reduces carbon intensity from 0.8 to 0.4 tons
of CO₂ per MWh, strengthening electricity supply for Batam and Bintan’s industrial growth.

Eka Satria, President Director & CEO of Medco Power Indonesia, said, “The Add-On project represents
another step forward in enhancing system efficiency and reliability. By generating more electricity from
the same energy source, it improves overall performance and lowers carbon intensity, reflecting our focus
on optimizing existing assets to meet the power needs.”

Roberto Lorato, CEO of MedcoEnergi, said, “This project demonstrates how MedcoEnergi continues to
build a more efficient and lower-carbon power portfolio, contributing to Indonesia’s energy reliability and
sustainable development.”

The project was completed with more than 2.7 million safe man-hours without a lost-time incident,
reaffirming Medco Power’s strong operational standards and commitment to safety and performance.
