NEXTDC Limited announced a major milestone in its long-term data centre development strategy with the Company securing a new data centre site in Western Sydney ("S4"). S4 is a significant long-term expansion opportunity that will provide data centre services to Hyperscale Cloud Providers in a new Availability Zone within the Sydney market not currently serviced by NEXTDC's existing data centres (S1, S2 and S3, which is currently under development). S4 will also allow Enterprise and Government customers to scale their critical infrastructure platforms in this important digital gateway region. The S4 site is in Horsley Park, approximately 42 kilometres west of Sydney's central business district and close to a major electricity substation as well as telecommunications, utilities, and public infrastructure. The site covers approximately 124,000sqm. Subject to Development Approval, it is expected to accommodate a data centre facility capable of approximately 300MW of capacity, in addition to housing our customers' mission critical operation centres, administrative offices and collaboration spaces. S4 is expected to generate more than 500 new jobs during the development phase over several years. The purchase price of the S4 site is approximately $124 million.
