Data centre provider Switch is planning to build a huge facility in Reno, Nevada, which it claims will be the largest data centre campus in the world once completed.

The Nevada-based company is already known for its massive SuperNap Las Vegas site – the largest existing data centre campus in the world – which is also undergoing further construction, after which it will measure almost 2.4mn sq. ft. Switch announced the addition of its Reno centre at the beginning of the year, when it said that eBay would be its anchor tenant and the cost of the project would amount to $1bn. Now Switch has said that the SuperNap Reno campus will cost $3bn when fully built.

The SuperNap Tahoe Reno 1 is the first stage of a project that will see Switch build up to seven data centre buildings of the same size, totalling 6.49mn sq. ft. The campus, located just east of Reno-Sparks, will sit alongside a Tesla battery manufacturing factory which is also currently under construction.

The Switch facility plans to offer 82,000 tons of cooling for a 150 megawatt data centre. The site will have a 300MVA substation. It will connect over the company’s high-speed network to the Las Vegas campus, and will link to connectivity hubs in Los Angeles and San Francisco. Switch suggests that this Reno-Vegas link will guarantee latency under seven milliseconds.

Reno is becoming a popular destination for data centre projects, with Apple and Rackspace moving into the area. The location is appealing for businesses due to its low power costs, economic incentives, skilled workforce and strong connectivity to the Bay area and the West Coast.

Rackspace recently announced that it had placed an application with local governors to receive 20 years of tax abatements following the launch of its new site in the Reno Technology Park, expected to open its doors in June 2017.
