CDC rolls six data centres into one application
CDC Data Centres has consolidated its expanded Kemps Creek proposal into a single planning application – avoiding the optics of repeatedly seeking council approval for additional buildings as the western Sydney campus grows.
The company initially proposed one data centre building on an 88.33 hectare holding.
However, following a request by Penrith City Council, a scheme for a six-building data centre campus has been brought forward for assessment under one application.
The combined peak power requirement would be about 1.4 gigawatts (GW).
Revised scheme
The revised scheme, at 845-901 Mamre Road, includes 1008 megawatts (MW) of information technology capacity across buildings KC1 to KC6.
That is twice the 504MW approved for CDC’s Marsden Park campus last November.
The indicative schedule allocates 168MW of IT capacity to each of KC1, KC2 and KC3, 144MW to KC4, 120MW to KC5 and 240MW to KC6.
The six buildings would contain 29 data halls, an administration building, security infrastructure and on-site electricity substation.
Staged delivery
CDC intends to deliver the campus in stages, beginning with KC1, KC2 and KC3, which would provide 504MW of IT capacity.
The initial works would also include the substation, administration building and a temporary car park. KC4, KC5 and KC6 would follow (continues below).
One substation and a single Transgrid connection would service the entire campus, with the infrastructure designed around the proposed ultimate capacity.
The buildings would be two storeys with a maximum height of 25.5 metres (compared with 35.2m under the original four-level design).
The expanded application also includes a road realignment, with a planned collector street that would have bisected the site relocated to the western perimeter.
The expanded holding spans 117.47ha, incorporating an additional 29.14ha allotment at 845-857 Mamre Rd.
Approval still required
CDC will prepare an Environmental Impact Statement addressing the expanded campus, including cumulative impacts and the proposed electricity connection.
The original application, lodged in July 2026, proposed a $1.8 billion development with 280 ongoing positions.
The revised development cost and employment estimates have not been established.
The application comes a month since realestatesource.com.au reported CDC had applied to develop a data centre campus at Gregadoo, south of Wagga Wagga.
