STT GDC Secures US$1.37B Green Financing for AI-Ready Johor Data Centre Campus

Singapore's data centre giants have been racing to build capacity wherever land and power allow — and increasingly, that means just across the Causeway. ST Telemedia Global Data Centres (STT GDC), the Temasek-linked operator behind some of Singapore's biggest server campuses, has now secured a green financing facility of up to US$1.37 billion (S$1.75 billion) to fund its STT Johor campus in Malaysia, a project explicitly designed for the AI workloads Singapore can no longer host at home.

The facility, announced on Aug 13, covers the first phase of the campus at Nusa Cemerlang Industrial Park in Iskandar Puteri, which is planned for up to 166 megawatts of IT load capacity supporting cloud, AI, high-performance computing and other digital workloads. The financing is led by a Singapore-heavy banking line-up: United Overseas Bank (Malaysia) is sole coordinator, with OCBC Bank (Malaysia), Standard Chartered Bank Malaysia and CIMB Bank acting as mandated lead arrangers. STT GDC group CFO Nelson Lim called the deal "an important milestone" reflecting bank confidence in Johor's long-term digital infrastructure fundamentals.

The green-loan structure is part of a broader push to make AI-era data centres sustainable. STT GDC's latest ESG report shows renewable energy covered 83.2% of its electricity consumption in 2025, carbon intensity down 70.5% from its 2021 baseline, and average power usage effectiveness improved 13% to 1.44 — meaningful numbers as hyperscalers come under pressure to account for the environmental cost of model training and inference.

The Johor campus is also designed to plug directly into the Johor-Singapore Special Economic Zone, which aims to deepen economic integration between the two sides of the Causeway. STT GDC launched a talent development programme there in April with the Johor Talent Development Council, Universiti Teknologi Malaysia and EPI Group, signalling that the project is as much about workforce as wattage. For Singapore, the deal is a reminder that its data centre strategy is increasingly regional — compute may sit in Johor, but the capital, customers and coordination remain Singaporean.

Why it matters for Singapore: With Singapore's own data centre moratorium-era constraints still shaping where capacity can be built, Johor has become the overflow valve for AI infrastructure demand. A US$1.37 billion green financing arranged largely by Singapore banks shows how the city-state's financial muscle is underwriting the region's AI build-out — and how the JS-SEZ is turning into a real two-way digital corridor rather than a slogan.
