Green Mountain Romford Data Centre

Colo-X analysis

The Green Mountain Romford data centre was first launched by Infinity Data Centres in 2010 who followed a wholesale model, selling the initial capacity to a mixture of carrier and banking sector customers.  Computacenter also have a Tier4 certified suite here of about 1MW.

As Infinity began the wind down of their business in 2015, selling sites in west London to Zenium and Virtus, this was one of the last to be sold, finally being acquired by Norwegian based Green Mountain in summer of 2022, including the vacant lot to the south.  Combined, both sites have the potential for some 40MW, though the existing Romford North site is about 22MW or 100,000 sq ft of net technical space.

Some pockets of good quality, Tier3 standard colocation space are available to smaller users, ranging in size from 50kW to 250kW – contact Colo-X for more details.  50kW minimum.

Green Mountain Romford facility description

Green Mountain’s Romford North data centre is a massive warehouse building able to offer around 350,000 sq ft of gross space and 130,000 sq ft of net technical capacity. 28MVA is available via dual 33kV power feeds. The Infinity model was to build out halls to each client’s specification, so standards vary, from Tier4 (Uptime Certified) to more usual Tier3.

The largest tenants on site are believed to be Verizon and RBS. Other tenants include Computacenter, who have taken 7,500 sq ft and who have built-out to an officially certified Tier 4 design standard.

As a further expansion option, Romford South is available on the opposite side of the road from the existing data centre and has a design to offer 18MW, or a slightly smaller capacity than the existing Romford North building.

Green Mountain are a Norwegian based data centre provider, wholly owned by a listed Israeli real estate fund, Azrieli Group. They operate 3 sites in southern Norway, one of which is an enormous former NATO ammunition bunker, but all 3 are closely tied to local hydro-electric power schemes and can offer capacity ranging from 25 to 75MW.  Again, the focus remains large scale, wholesale customers.

Green Mountain Romford is one of only three sites available on Colo-X located to the east of London Docklands, the other two being the huge 64MW NTT Dagenham LON1 data centre and the more retail focussed Custodian Dartord, a 5MW site.
