STACK JHB01 Iskandar Puteri Data Center Campus, also known as STACK Johor Bahru Campus, is a data center project in Iskandar Puteri, Johor, MY developed and operated by STACK Infrastructure. 10.8-hectare flagship Johor Bahru campus with two facilities totaling about one million square feet and 220 MW. TNB 275 kV infrastructure, onsite substation, redundant site entries and a fiber ring to multiple telecommunications networks. The January 2025 project announcement states 220 MW, while STACK’s current APAC index reports 216 MW for Johor Bahru. The cited identity or capacity sources conflict and do not establish a single project-scoped capacity figure.
