NTT Ltd., through its Global Data Centers division, has just announced the opening of its new London data center which is sited in Hemel Hempstead, expected to offer 9,600 square meters of IT space.

Codenamed Hemel Hempstead 4, the new 24MW facility is NTT’s 7th data center across London and the fourth in Hemel Hempstead. Other facilities are located in Slough and Dagenham. According to NTT, this opening delivers half of the data center capacity.

As designed, the London data center, as with all NTT data centers in the UK, uses 100% renewable energy and is expected to exhibit low water usage (WUE).

“As the third-largest data center provider in the world, NTT continues to significantly accelerate our investment into the London and UK market as a key global location. This investment provides scalable data center and connectivity infrastructure for our clients’ digital transformation needs,” said Masaaki Moribayashi, President and Board Director at NTT Ltd.

As first announced in September 2020, the opening of NTT’s Hemel Hempstead 4 is part of the company’s £500 million data center expansion plan which also powered the development and delivery of its Dagenham data center (London 1), located about 10 miles east of London’s city center.

To create its fiber-connected London hub, NTT also connects its Dagenham, Hemel Hempstead, and Slough data centers, with an option to connect to the London Stock Exchange. These facilities are further integrated with other NTT global data center facilities.

In the U.S., NTT is also developing its new 102-acre data center campus in Phoenix, Arizona which will house seven data centers. The first of the seven planned data centers on the campus, NTT Phoenix PH1, is already underway, slated to open in early 2022, and will feature 36MW of critical IT load capacity while the entire campus is expected to support up to 240MW of IT load.
