Global Switch wants to expand its data center site in Sydney, Australia.

The company recently filed with New South Wales planning authorities for the expansion of its existing data center buildings, including two additional levels, and the conversion of existing floor space into plant and electrical space.

The project will result in an increased building height of 12m, and increase in power consumption by 47.5MW.

Global Switch currently operates two adjacent conjoined data center buildings in the Ultimo area of Sydney on an 11,090 sqm (119,370 sq ft) site. The 392-422 Harris Street property is known as Sydney West, while 273 Pyrmont Street is known as Sydney East.

The seven-story West was constructed in the early 2000s and currently offers 20.5MW. The six-story East was built in the mid to late 2010s and currently offers 22MW.

The expansion will add 24.5MW to West, and 23MW to East, taking the two buildings to a combined 90MW. As most of the expansion will be plant rooms, the project will allow for greater density rather than more white space at the site.

“As a result of escalating demand in the digital economy and the continuous technological advancements in the data center industry, the existing Global Switch data centre needs to be augmented and expanded,” application documents said. “As aforementioned, the proposal is required to meet increased demand for digital services and data services and is viewed as a preferred outcome for Global Switch as compared to finding a new location within the Pyrmont locality.”

Several Australian governmental departments have left Global Switch’s Sydney site after Chinese investors took control of Global Switch, including the Department of Home Affairs, the Australian Securities and Investments Commission, the Australian Digital Health Agency, and the Australian Communications Media Authority.

The current Chinese stakeholders for Global Switch, Jiangsu Shagang Group, are allegedly looking to sell their shares, with interest expressed by numerous operators and investors including EQT and NextDC.
