Jakarta, INTI - Equinix is preparing to expand capacity at its first data center in Jakarta, known as JK1. Built through a partnership with PT Astra International, the facility has been operational since May 2025, offering a capacity of 550 cabinets, equivalent to around 2.5 megawatts.
“For this second phase (at the same site), we have prepared four data halls. They can accommodate around 1,100 cabinets,” said Haris Izme, Managing Director of Equinix Indonesia, during an exclusive media luncheon in Jakarta on Tuesday, February 3, 2026.
However, Haris declined to provide further details on the scale of the capacity increase, noting that discussions are still ongoing with state-owned electricity company PT Perusahaan Listrik Negara (PLN).
He explained that the expansion of data hall capacity, or the addition of dedicated physical space within the Equinix data center, could also support the development of JK2, although he stopped short of revealing further plans for the project.
“So if JK1 can be expanded further, then it will be ready for the second phase,” he said.
The expansion of space at the JK1 data center is moving ahead even though the facility has not yet reached full occupancy. Currently, the site serves at least 70 customers. “In other countries, such as South Africa, there were only around 10 customers in the first year after launch,” he added.
Despite not yet being fully occupied, Equinix is pushing ahead with the expansion of JK1 to create opportunities to attract more customers in the future.
Equinix’s customer base spans a wide range of industries, including telecommunications providers, internet service companies, large multi-industry conglomerates, healthcare, content delivery networks, cybersecurity firms, pharmaceutical companies, and banking and financial institutions.
The Equinix data center also provides the platform required to support distributed artificial intelligence infrastructure, including within the cabinet capacity planned for the second development phase of JK1.
How Equinix Is Addressing High Electricity and Water Consumption
Equinix has outlined a strategy to achieve net-zero emissions by 2040. Ahead of that milestone, Haris said the company is targeting a transition to become a renewable energy-driven business by 2030.
One of the key challenges in reaching this goal lies in managing electricity and water usage, both of which are essential for operating data centers and cooling their systems.
Haris noted that the current power supply at JK1 is secure and fully provided by state-owned utility PLN. He added that, where possible, Equinix also hopes to tap into renewable energy sources in the future.
“Renewable energy is already on our list. If green energy becomes available in Jakarta, we would certainly like to use it, but at the moment there is no direct green energy source here. Everything is still supplied by PLN,” Haris said.
However, he confirmed that Equinix has already been purchasing Renewable Energy Certificates (RECs). As a result, Equinix’s global operations are now fully supported by renewable energy.
“Of course, if green power becomes available in Jakarta and the pricing makes sense, we are absolutely sure there will be customers who also want to use green energy. So far, our renewable energy certificates are already 100% covered,” he added.
The second development phase of JK1 has also been designed with liquid cooling technology, which enables greater efficiency in handling high-performance computing demands.
“There are pipes that connect directly to the chip. If you imagine something like a gaming machine on a desktop, it has a GPU or CPU, and on top of it there is a fan. That fan has pipes, and inside those pipes there is liquid. The liquid absorbs the heat and carries it away,” Haris explained.
The JK1 data center has also adopted liquid cooling systems to help reduce potential water consumption.
Conclusion
Equinix’s expansion of its JK1 data center in Jakarta reflects the company’s confidence in Indonesia’s growing digital economy and rising demand for high-performance infrastructure. By increasing capacity, supporting distributed AI workloads, and adopting advanced liquid cooling systems, Equinix is positioning JK1 to serve next-generation computing needs. At the same time, its commitment to renewable energy through certificates and long-term sustainability targets highlights a balanced approach between growth and environmental responsibility. Together, these efforts strengthen Jakarta’s role as a key regional hub for data centers and digital transformation.
