Overview
Infrastructure
Tier guide →- Connectivity
- Cassava Technologies pan-African fibre-optic network (high-speed, ultra-low-latency)
Pan-African fibre network owned by Cassava Technologies, described as high-speed ultra-low-latency.
Cooling adequacy for AI workloads has not been independently assessed for this facility.
AI data centres require ~100 kW/rack (10× conventional). Liquid cooling at rack level is the key differentiator. Learn more →
Power
PPAs & wheeling →- Grid utility
- Eskom
- Grid carbon intensity
- 900 g CO₂/kWh
- PPA partners
- Distributed Power Africa
Eskom grid average ~900 gCO₂/kWh per Eskom Integrated Reports (2022-23). Grid-level figure, not facility-specific.
12MW solar farm near Bloemfontein with Distributed Power Africa, powering ADC SA portfolio under wheeling.
Grid carbon context
900 g CO₂/kWh — Very high — coal-heavy grid
2.1× the global average (436 g CO₂/kWh, IEA 2022). Compare: France ~60, UK ~175, US ~400 g CO₂/kWh.
Grid-level estimate. PPAs and on-site renewables may reduce the effective carbon footprint.
