As with all datacentres, provisioning the extra power to the site was a challenge. Originally, Telecity ordered 24MVA of power capacity from utility Scottish and Southern Energy, which has a distribution station around a mile away from the facility's north Acton site. This proved to be difficult, so it changed the order to 60MVA, which was a large enough order for the utility to agree to construct a substation and transformer (pictured) onsite.
Because a National Grid distribution point is around 150 metres away from the substation, less power is lost between the two during transmission. The power supply was one of Telecity's main considerations when choosing the site for Powergate.
Coupland explained that the co-location provider is in talks with energy suppliers to know "where they are in terms of grid capacity", so they can together plan future datacentres.

When completed, the expanded facility will have an additional 21MW of IT power at its disposal and over 100,000 additional square feet of IT space, according to Telecity.
The old data halls and the new ones will be linked by an overhead walkway (pictured). The company hopes to move the PUE down from 1.65 to 1.35 by tweaking the overall design.
