This week, STT GDC broke ground on its third data centre in Indonesia and also topped off its second facility.

The company has been expanding rapidly in Jakarta, with four data centres in different stages of construction.

STT GDC in Indonesia

All STT GDC's data centres in Indonesia are currently located in the Greenland International Industrial Centre (GIIC).

  • STT Jakarta 1 (18MW) - Went live in 2023.
  • STT Jakarta 2 (24MW) - Operational by 2026.
  • STT Jakarta 3 (24MW) - Groundbreaking.
  • STT Jakarta 4 (32MW) - Under development.

STT Jakarta 2 and STT Jakarta 3 will be supported by a dedicated 150kV substation and will be AI-ready for high-performance, high-density workloads.

Additional details for STT Jakarta 2 and STT Jakarta 3 are not publicly available at this point.

STT Jakarta 1

A data sheet available for STT Jakarta 1 offers more clarity, notably pegging its capacity at 18MW of IT load - indicating that all figures are for IT loads.

Some details jumped out at me:

  • Mentions of walls units.
  • Use of adiabatic chillers.
  • Buffer tanks for chilled water.
  • Good floor loading of 15 kN/sqm.

My overall impression is that of an advanced data centre but one designed without AI in mind.

Of course, construction for STT Jakarta 1 would already have started when ChatGPT came out in Nov 2022. From the announcement, STT Jakarta 2 onwards will likely be designed very differently.

Power infrastructure at GIIC

Unlike some industrial parks in Indonesia, GIIC doesn't operate its own independent power plant but relies on state-owned PLN for its power supply.

With support from the top to meet the government's vision of becoming a hub for data centres, it does feature premium facilities and electricity infrastructure.

  • Its own wastewater treatment plant.
  • Supported by extra-high voltage substations.
  • Access to green energy options through PLN.

I look forward to learning more about STT Jakarta 2 and STT Jakarta 3 in the year ahead!
