Liberty London is incorporated into two buildings, Lasenby House and Tudor Building. Due to the lease agreement, Liberty London (Tudor Building) had to migrate from the existing electricity supply situated in Lasenby House. This in turn would allow Lasenby House to use the full capacity of their existing service and enable Tudor Building to be self sufficient.

The installation of an 11kV Sub-station, 1000kVA Cast Resin Transformer, 1600amp Main LV switch panel, all the earthing arrangements and de-commissioning of existing panels were to be undertaken by Powercor whilst the department store was closed for trading.

Powercor worked in conjunction with haydengreen, SSE Contracting, UK Power Networks, the consultants and the management at Liberty London to ensure that a feasibility study was carried out to understand what Liberty’s actual power consumption was and that the proposed installation would meet their future development plans.

When the specification was agreed, Powercor’s team of engineers prepared several previously unused rooms to maximise space for the installation of the sub-station as well as the transformer and main LV panel.

A ladder rack and cable tray were installed for containment and when all of the preparation work was completed and the Transformer and panels delivered, a shutdown over four nights was arranged so that we could migrate the existing and new supplies into the relevant distribution panels.

The whole installation was tested and inspected to all of the current IET Wiring Regulations and the rooms and installation was handed back to Liberty London with minimal disruption and to the highest standard of workmanship.
