Fujitsu will invest $12.2 million to upgrade its Western Sydney data centre and provide more power to the site as part of a wider plan to modernise its Oceania facilities.
In May Fujitsu announced the first investment into the project, a $10 million funding pot to upgrade its Malaga, Perth facility to achieve Tier IV certification.
Today it said it would spend a further $12.2 million to modernise power infrastructure and internal capacity at its Greystanes, Western Sydney facility.
Around $7 million will be allocated to the power infrastructure upgrade and the remaining $5.2 million will go towards improving internal infrastructure capacity.
Fujitsu will install two 33kV high-voltage feeders into the facility, which will run to the Endeavour Energy transmission station in nearby Blacktown via two separate underground channels.
The company will need to tunnel underneath both the M4 motorway and the Great Western Highway to reach the Endeavour Energy station, providing some "interesting geographical challenges", Fujitsu Australia chief Mike Foster said.
The feeders will provider an extra 30MVA of power to the site, Fujitsu said.
The project - which is being run in partnership with Connect Infrastructure - will span six months with construction due to start in August.
The Western Sydney and Perth facilities are the first of Fujitsu's seven national data centres - which collectively span 25,000 square metres - to receive upgrades as part of the company's roadmap to 2025. The company has 150 data centres globally.
The roadmap aims to provide reliable, secure and sustainable data centre infrastructure that will allow Fujitsu to take advantage of emerging trends like the internet of things.
"We are seeing an ever increasing demand from our customers for enterprise-grade data centre facilities as they prepare for digital transformation and the evolving data needs of a hyper connected world," Foster said.
