Telehouse opened a new primary power substation next to its London Docklands data centers.
The move allows for a direct connection to the National Grid and future-proofs the power needs of the Telehouse London data centers for a 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 substation has been designed and built in conjunction with Mace, the international construction company and Swiss power giant ABB.
The substation was completed within an 18-month period.

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 said: “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.”
