Telehouse opens primary substation for its London Data Centres

Telehouse the global data centre provider has opened a new primary power substation alongside its existing London Docklands data centres. The move will increase the impact of potential electricity capacity and allows for a direct connection to the National Grid.

Power and electrical shortages in London have been an increasing concern ever since the Olympics took hold of the city last year and securing consistent power availability is a growing headache for many high-power usage companies in the capital.

The move future-proofs the Telehouse business and secures enough power to serve its fast-growing customer base for another decade.  The Docklands site is also supplied by Smartest Energy, the renewable energy provider allowing Telehouse to power its data centres with green electricity. In addition to customer service benefits, the direct connection to the National Grid means a reduction in transmission losses, reducing overall energy costs and carbon tax.  

The new substation has been designed and built in conjunction with Mace, the international construction company and ABB, the major power distribution technologist. The new substation was completed within a swift 18-month period setting a new industry benchmark. 

The £15 million substation has a total capacity of 50MVA and two 132kV power lines directly connected to the National Grid, designed and constructed to a specification exceeding the highest UKPN tier of substations in technical delivery. The Docklands site now reaches 40MW scalable to 50MW and holds two 50kVA transformers offering N+N redundancy, improving the overall uptime of its power provisioning levels for its customers.

Robert Harris, Technical Director at Telehouse comments, “The completion of this substation was achieved within a short timeframe and makes Telehouse the only commercial data centre provider with a privately owned primary substation. This latest development serves to reiterate our close working relationship with the National Grid, enabling us to ensure more reliable and consistent power in an environmentally responsible manner.”
