The 30MW addition expands JB4 to being the largest standalone data centre built in Africa, servicing 50MW of critical IT power load, Teraco said in a statement on Monday.
"This new phase at JB4 comprises six data halls, incorporates numerous new design enhancements and - each hall supports 5MW of allocated critical IT power load," the company said.
The new data halls are "liquid-to-liquid cooling" enabled, allowing clients to deploy high-density, air-cooled cloud deployments and direct-to-chip cooling for dense artificial intelligence workloads.
"JB4 has been designed with sustainability at its core, incorporating a state-of-the-art closed-loop chilled water system that provides free air cooling, coupled with AI enabled technology to configure data hall cooling in real time, based on IT load and load dispersion," Teraco said.
Teraco's data centres now have 189MW of critical power load, including the Isando campus JB1/JB3/JB5: 70MW, Bredell campus JB2/JB4: 64MW, Cape Town campus CT1/CT2: 53MW and Durban DB1: 2MW. c 2025 NewsCentral Media
