Data Center Campus
STACK Infrastructure plans a two-building hyperscale campus on a 7.7-hectare lot at 78 Lockwood Road, Erskine Park, in western Sydney, fed by two 330 kV circuits from Transgrid's Sydney West substation. First building planned for 2028, with the second planned for 2029.
STACK SYD01 is a planned hyperscale data centre campus at 78 Lockwood Road, Erskine Park, in the Penrith local government area of western Sydney. It sits about 40 km west of the Sydney CBD and 10 km north-east of Western Sydney International Airport.
Land. The campus occupies Lot 101 in DP 1268632, an irregular 7.7-hectare lot in the former Fitzpatrick Industrial Estate, now Erskine Business Park. Lenore Drive bounds it to the north and the Ropes Creek biodiversity corridor to the east. The lot was subdivided under DA20/0493 and delivered as a levelled development pad. ESR's LOGOS bought the site in 2024 and marketed it as the Erskine Park Logistics Estate. STACK is developing SYD01 through STACK Infrastructure Australia (78 Lockwood Road) Pty Ltd.
Design. Each of the two three-storey buildings has two levels of data halls around a central plant floor, with offices facing Lenore Drive. Cooling uses air-cooled chillers, so no water is used for cooling. The roofs carry solar arrays. The design PUE target is 1.24.
Power infrastructure. Two underground 330 kV circuits run about 2.1 km along Lenore Drive from Transgrid's Sydney West 330 kV substation on Old Wallgrove Road. The cables are bored under Ropes Creek. They feed a Transgrid-owned 330 kV GIS switchroom on the site. A STACK-owned substation steps the supply down through three 330/132 kV transformers and eight 90 MVA 132/11 kV transformers, four per building in N+1. Backup power comes from 188 diesel generators of 3.1 MW each in a four-level gantry, with lithium-ion UPS. The site lies in Endeavour Energy's distribution area.
Planning. The campus is State Significant Development SSD-82211208. The planning requirements (SEARs) were issued in April 2025. The EIS was lodged in November 2025 and exhibited from December 2025 to January 2026. STACK amended the application in April 2026 to add the 330 kV cable route, and the amendment was exhibited in April and May 2026. In October 2026 the NSW planning department was still assessing the application.

STACK Infrastructure is a privately held platform sponsored by IPI Partners that focuses on large scale wholesale capacity and campus development for hyperscale and enterprise customers.
The company was launched in 2019 when IPI combined the remaining Infomart Data Centers assets with selected T5 Data Centers facilities, and industry coverage at launch cited eight data centers across six U.S. markets totaling about 100 MW. In March 2022, IPI unified DigiPlex in the Nordics and SUPERNAP Italia in Milan under the STACK brand to form STACK EMEA, expanding the platform across Europe. STACK has since added international sites, including the first phase of a 56 MW campus in Toronto and its first Australian data center in Melbourne. Core services referenced by the company and trade press include wholesale colocation, build to suit, and powered shell solutions.
