</a>NEXTDC S4 is a planned hyperscale-oriented data centre at Horsley Park in western Sydney, listed by the operator as in development on its S4 page and as in planning in its location menu. NEXTDC states 124,000 m² of technical space and 365 MW of IT capacity, with a Tier IV Uptime Institute certification as a target rather than an achieved status. The operator says S4 will be purpose-built for ecosystem partners, hyperscale cloud providers, enterprises and government customers and is positioned on several network interconnects. This makes it NEXTDC's largest listed Sydney project by capacity, ahead of S3 Artarmon (80 MW) and S5 Macquarie Park (80+ MW), and S7 Eastern Creek is separately listed at 550+ MW. The street address, delivery date and cooling design are not published on the page.
