This combination creates the foundation for what is increasingly referred to as “green data centers.”
The Kamojang Blueprint
At the center of PGEO’s strategy is a pilot project in Kamojang, West Java—one of Indonesia’s most established geothermal fields.
The plan is to develop a 5 MW data center facility, powered directly by a dedicated geothermal plant of the same capacity.
This integrated approach is critical.
Instead of relying on grid electricity, the data center will be powered by on-site geothermal generation, ensuring both efficiency and sustainability. The project is expected to:
- Serve as a proof of concept
- Demonstrate the viability of geothermal-powered digital infrastructure
- Attract future investors and partners
- Establish PGEO as a pioneer in green data centers
In many ways, Kamojang is more than a project—it is a prototype for the future.
Beyond Power: Building a Digital Ecosystem
PGEO’s ambitions extend beyond simply supplying electricity to data centers. The company aims to participate directly in the digital value chain.
This includes:
- Data processing services
- Cloud infrastructure hosting
- Server and network management
- Digital storage solutions
By doing so, PGEO is effectively transforming itself from an energy producer into a hybrid energy-tech company.
This evolution reflects a broader global trend, where energy companies are seeking to capture more value by moving closer to end-users. In PGEO’s case, the end-users are not households or factories—but servers, algorithms, and digital platforms.
