Microsoft Data Center Expansion on the Grange Castle Park

In 2016 Microsoft received approval to build three additional data centers at the Grange Castle Business Park in Clondalkin to complement their three data centers.

Power is Scarce

Microsoft is building a power station for its data center in the Grange Castle Business Park, Clondalkin, as a surge in demand has made local infrastructure insufficient to sustain the facility.

The company will set up 16 gas-powered generators which will provide 18MW to one of its four data centers on site. The semi-state-owned electricity transmission company, EirGrid, has stated that the power network is struggling to meet requirements at the Grange Castle Business Park. Source (


A key focus of the Dublin facility is the use of outside air to cool the facility and servers, a process known as free cooling or air-side economization. Instead of using chillers or cooling towers, rooftop air handling units drop outside air down into the server rooms and then pull the return air from the racks back through the rooftop.
