Data storage firm Iron Mountain has opened another data center in Arizona, with its power usage offset entirely by renewable energy market trading.

The firm will now have two at its site in Phoenix, Arizona, and 14 in total. It said yesterday it had completed phase one of the latest building, having equipped it with a 4MW power capacity. Upon completion, it will be three stories high, and will have a capacity to deliver 48MW of power to servers across 530,000 square feet (49,200 sq m) of floor space.

The 40-acre campus has spare land and will be capable of supporting 100MW of IT equipment when it is fully developed, the firm said. The site is powered from the electric grid, but the firm offsets its use with renewable energy, by making power purchase agreements for equally as much renewable energy.

The new building, called AZP-2, will be on the same campus as the company's existing data center, AZP-1 - a 588,000 sq ft (55,000 sq m) building it acquired when it bought IO Data Centers last year.

"AZP-2 strengthens our global data center platform, and increases our ability to meet the demand from customers in the Western US," said Mark Kidd, EVP and GM of data centers at Iron Mountain, in a press release. Of possible sites in the US, Arizona was among the least at risk of being struck by natural disasters. Phoenix had the second-most data center leases among US locations in 2018, behind Northern Virginia, according to property investor CBRE.
