SUNeVision MEGA IDC in Tseung Kwan O has a conservative 180 MW full-build IT design, not operating capacity. Phase One launched in 2024 with 50 MW. The 2025/26 report forecasts occupancy rising from about 30% toward or above 70% as customer implementation proceeds, not achieved occupancy. Combined remaining phases target 2028 readiness, superseding the earlier 2026/27 schedule. MEGA Plus and TKO Connect are network links, not additional campus buildings. Current energized load and project-specific debt allocation remain unverified; SUNeVision’s group-wide expansion must not be assigned to this site.

Reviewed sun phase1 area context

Source report

SUNeVision’s 2025/26 annual report describes MEGA IDC Phase One as approximately 500,000 square feet of gross floor area and 50 MW of power capacity. This is a dated operator specification, not measured occupied load; the report’s group wide 150-to-280 MW expansion must not be assigned to this campus.

Source

Reviewed sun phase2 area context

Source report

In the 2025/26 report, SUNeVision plans to combine the formerly staged Phase 2a and Phase 2b into one development, targeting readiness in 2028 and approximately 700,000 square feet of data centre space. This is a development forecast, not completed delivery.

Additional project facts

Reviewed sun occupancy forecast context

Source report

The 2025/26 report expects a major customer commitment to raise MEGA IDC Phase One occupancy from approximately 30% to around 70% upon full implementation. Its Chairman describes move in as in progress and expects occupancy above 70%. These are prospective implementation statements, not achieved 70% occupancy or occupied electrical load.
