          Medco Power Commences Commercial Operations of Ijen Geothermal Power Plant

Ijen - East Java, [7] February 2025 – PT Medco Power Indonesia (Medco Power), a subsidiary of PT
Medco Energi Internasional Tbk (MedcoEnergi), through its business unit PT Medco Cahaya Geothermal
(MCG), a jointly owned company of Medco Power and Ormat Technologies (NYSE:ORA), has

power facility in East Java (Project). This Project marks a significant step forward in Indonesia’s renewable
energy development. By utilizing advanced technology and robust infrastructure, Medco Power is proud
to support the government’s energy transition agenda and renewable energy targets.

The Ijen Geothermal Power Plant, with a planned total capacity of 110 MW, began operations with its first
phase delivering 35 MW to the Java electricity grid, under a 30-year purchase power agreement (PPA).
Supported by 83 transmission towers and a 150kV transmission line, the project will enhance grid stability
and expects to generate power to approximately 85,000 households in Java-Bali system. In 2024, Ijen
received awards on occupational safety and health from the Directorate General of Renewable Energy
and Energy Conservation, and zero accident award from East Java provincial government.

Ijen will be the second geothermal facility of Medco Power, after Sarulla in North Sumatera. Medco Power
is also evaluating other geothermal prospects in Bonjol, West Sumatera and Samosir, North Sumatra.

Eka Satria, President Director of Medco Power, stated, “The successful development of Ijen Geothermal
Phase-1 demonstrates Medco Power’s capability to harness Indonesia’s geothermal resources using the
latest technologies. This milestone reinforces our commitment to expand our renewable energy portfolio
and underscores our dedication to support Indonesia’s plan to accelerate renewable energy
development.”

Roberto Lorato, CEO of MedcoEnergi, added, “The commencement of operations at Ijen Geothermal
reinforces MedcoEnergi’s dedication to delivering sustainable energy solutions. This project is also an
important part of our roadmap to achieve Net Zero Emissions for Scope 1 and 2 by 2050, and Scope 3 by
2060, while supporting Indonesia’s energy security and climate goals.”

Medco Power extends its appreciation to the Indonesian government, PT PLN (Persero), project partners,
