Colo Equinix has revealed plans to double the size of its latest London data centre, LD6, six months after it opened the site in Slough on April 16.

The second phase of the expansion will add 6MW of power, 1385 cabinets and 43,000 sq ft of floor space to the hub.

The company said the expansion – expected to be completed by Q3 2016 – has come after high demand from customers who are filling up the site’s current 86,000 sq ft.

Once fully built, the data centre will have 129,000 sq ft of space. At the time of the launch, Equinix said that LD6 was the first UK data centre to be built to conserve energy and has a PUE of 1.4.

Ross Henderson, Equinix’s technical facilities director UK told DCD: "Equinix can confirm that plans have been put in place to expand the data centre capacity at LD6 in Slough.

"Currently Equinix’s LD6 data centre is at 50% capacity, which only represents the completion of phase one. Work has now started on phase two, which is expected to be complete by Q3 2016, brings the available space in the Slough campus to over 32,600 sq m."

The provider is also currently awaiting for the European Commission to decide on its $3.7 billion merger with colo TelecityGroup. The decision is due on November 13 and, if approved, would make Equinix the largest data centre player in EMEA with a 14% market share , according to Synergy Research Group.

The company has also posted revenues of $686.6 million for Q3 2015, an increase of 3% over Q2. It has reported net income of $41.1 million and capital expenditures which amounted to $216.0 million, down from $221.3 million in Q2 but up to $156.0 million compared to Q3 2014.
