AI-DC KOREA ANALYSIS
Interpretation and Verification Points
The 400 MW figure on the official page refers to the design capacity for power supply expansion, not the current IT load. It must be displayed separately from the currently disclosed total UPS capacity of 40.8 MW, and the available rental capacity requires confirmation from the operator.
Principles for Interpreting Numbers
Power supply capacity refers to the range of power designed and contracted to be received from KEPCO; UPS capacity refers to the size of the uninterruptible power supply system; and IT load refers to the power actually allocated to IT equipment. Do not make estimates unless these are distinguished in the published data.
