Digital Realty signals $365 million boost for Western Melbourne

MELBOURNE – 15 February 2012 – At a ground-breaking ceremony today for the first of two planned data centres at Deer Park in the Western Melbourne Region, Digital Realty Trust, Inc. (NYSE:DLR), a leading global provider of data centre solutions, announced that the entire project is expected to have a positive economic impact on the region estimated at $A365 million.

The event was attended by the Victorian Government Minister for Technology, Mr Gordon Rich-Phillips as well as numerous additional members of the business community.

Mr Kris Kumar, Regional Head, Asia Pacific at Digital Realty said: “In addition to direct economic impact projected to be approximately $365 million, we believe there will be a ripple effect on regional businesses which will also benefit western Melbourne significantly. There is also potential for training and skills development for employees in small to medium enterprises in the data centre industry.”

He said the data centre developments are expected to provide approximately 220 direct jobs in the construction and operations phases, and more than 450 additional indirect jobs in the region.

Mr Kumar said: "We are actively engaged in discussions with a number of serious prospects for our Australian data centres. With our Australian staff in place, we are able to deliver secure, reliable and cost effective data centre solutions to customers that are expanding their IT operations in the region."

Digital Realty completed the acquisition of the 30,250 sq m development site at 72 and 98 Radnor Drive, Deer Park, within the Paramount Industrial Park development, in August 2011 for a purchase price of approximately $A4.1 million. Already Digital Realty has announced that National Australia Bank has signed a long-term Turn-Key Datacentre® lease for the first building, at 98 Radnor Drive. The lease was signed in the fourth quarter of 2011. This new 5,000 square metre data centre facility is scheduled for completion in early 2013. The first building constructed will be capable of supporting the development of two 1440 kW Turn-Key Datacentre® PODs1. The second project, 72 Radnor Drive, will be capable of supporting the development of four 440 kW Turn-Key Datacentre PODs.

Digital Realty has also acquired a 3.48 hectare development site in Sydney, for a purchase price of approximately $A10.7 million. The site, located in Erskine Park, an industrial precinct located in the Western Sydney Employment Hub, is capable of supporting approximately 18,600 square meters of data centre development with over 11.5MW of IT capacity.

1 Digital Realty’s POD Architecture’s® combination of standard components and incremental methodology dramatically reduces the time required for the company to complete the construction of each 900 – 1,100 sqm of space.
