Data Center Campus
Stack: Iskandar Puteri JHB01 Campus
STACK's JHB01 campus occupies a 10.8-hectare former steel-fabrication site in the SILC industrial park in Iskandar Puteri, Johor, with two data center buildings fed by an on-site TNB 275 kV substation. Construction began in 2025, with the second building planned for 2028.
Campus at a Glance
STACK Infrastructure's JHB01 campus sits in the SILC (Southern Industrial and Logistics Clusters) industrial park in Iskandar Puteri, Johor, about 10 minutes from the Malaysia-Singapore Second Link crossing. It is STACK's first campus in Malaysia. STACK announced it in January 2025.
Land. The campus occupies a 10.8-hectare freehold lot at 27 Jalan SiLC 1/5, on the corner of Persiaran SiLC. The lot was Axis Steel Centre @ SiLC, a steel fabrication plant. Axis REIT sold it to a data center operator for RM162 million, and the sale closed on 12 December 2024. The old factory buildings were cleared in early 2025.
Power and infrastructure. Tenaga Nasional Berhad (TNB) supplies the campus at 275 kV through a 300 MW on-site substation, with dual utility feeds. Generators and UPS run in N+1 blocks, with at least 24 hours of fuel stored on site. Cooling uses closed-loop water with air-cooled chillers, and the design supports liquid-to-chip cooling. Diverse fibre entrances, dual main distribution frames and a fibre ring to carrier manholes serve the site.
Ownership and investment. STACK Infrastructure develops and owns the campus. Funds managed by Blue Owl Digital Infrastructure own STACK's Asia-Pacific business. In August 2025, Malaysia's trade minister put STACK's planned investment at RM7 billion (US$1.66 billion). The buildings take shell, build-to-suit and turnkey deployments.

Developer
STACK Infrastructure is a privately held platform sponsored by IPI Partners that focuses on large scale wholesale capacity and campus development for hyperscale and enterprise customers.
The company was launched in 2019 when IPI combined the remaining Infomart Data Centers assets with selected T5 Data Centers facilities, and industry coverage at launch cited eight data centers across six U.S. markets totaling about 100 MW. In March 2022, IPI unified DigiPlex in the Nordics and SUPERNAP Italia in Milan under the STACK brand to form STACK EMEA, expanding the platform across Europe. STACK has since added international sites, including the first phase of a 56 MW campus in Toronto and its first Australian data center in Melbourne. Core services referenced by the company and trade press include wholesale colocation, build to suit, and powered shell solutions.
