NTT has opened a new data center in London and plans to expand one of its existing sites in the city.

NTT Global Data Centers this week said it opened its 7th London data center site in Hemel Hempstead – known as Hemel Hempstead 4 – in December 2021, delivering half its full capacity in phase 1, and will add another 9,600 sqm of space and 24MW of capacity when fully built out. Work began on the data center in September 2020.

The company also said it was also planning investments to expand its capacity at its London 1 facility in Dagenham, East London that was opened in 2020.

The company’s London data centers currently deliver more 53MW of capacity, and could see the company more than 120MW at full build-out. NTT said Hemel Hempstead 4, like all its UK facilities, would be powered by 100 percent renewable energy.

Masaaki Moribayashi, president and board director at NTT Ltd. said: “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.”
