A development of twin hotels known as The Gantry in Stratford, London required two looped substations from a High Voltage (HV) point of connection on a busy road.

The Gantry includes a 285 bedroom hotel over 18-storeys by the Hilton Curio Collection and a 136 room longstay aparthotel over 17-storeys by Adagio.

As the development also includes new bars and restaurants on the lower floors and a new sky-bar on the 18th floor, the overall load was 2MVA.

The Point of Connection was granted by UKPN and involved a road crossing and considerable run to site along a block-paved walkway. Alongside it being a very busy construction site, the DLR station and Westfield shopping centre are in close proximity.


  • The installation comprised a 1MVA substation and 1.5MVA substation, each providing a LV bulk-metered supply in an adjacent switchroom.

  • Both substations were midel-filled due to their location and internal rooms.

  • Due to the number of contractors onsite, the work was programmed to be flexible to the site requirements.

  • A robust traffic management plan was put in place offsite to ensure minimal disruption to the general public.

Darren Huxley, Project Manager commented: "A neat and quality installation on a very busy site. Great to be involved with such an iconic development."
