SUNeVision Holdings Ltd. (SEHK: 1686), operating under its iAdvantage brand, is the largest data centre operator in Hong Kong, running a portfolio of eight facilities across the territory as of 2025 with a combined 280+MW of power capacity across roughly three million square feet of gross floor area. As the technology arm of major property developer Sun Hung Kai Properties, it owns and builds most of its own buildings rather than leasing wholesale space, and its flagship MEGA-i facility in Chai Wan hosts over 200 telecom carriers and points of presence for nine submarine cable systems, making it one of the region’s densest interconnection hubs. Its newest and largest project, MEGA IDC in Tseung Kwan O, is explicitly positioned as an AI-ready hyperscale facility built to meet the power and cooling demands of cloud and AI customers, with over HK$15 billion invested across its multi-phase build-out.
