Abstract: |
A built heritage assessment and photographic survey was carried out of the overhead power transmission lines and their associated structures in the Lower Lea Valley, prior to the removal of the transmission towers, or pylons, and the underground diversion of the power lines. Overhead transmission lines were first erected in the Lower Lea Valley in 1953, as part of a 132kV line transmitting electricity from Brimsdown power station in Enfield, to Brunswick Wharf power station, which was adjacent to East India Dock Basin. Parts of this transmission network were reused when two new overhead transmission lines were installed in 1971; a 275kV line and a 132kV diversion for local electricity supply, which both ran from West Ham power station to Hackney substation; the earlier transmission towers have since been renewed. The placement of the transmission towers in the landscape broadly followed the 'Holford Rules', a set of guidelines drawn up by the National Grid in the 1950s which dictated the placement of pylons, and ensured they would be situated in visually unobtrusive places, such as valleys and industrial corridors in towns and cities. Subsequent National Grid planning guidelines restricted the nature of development around electricity transmission networks. A series of site visits resulted in the comprehensive photography of the transmission towers, substations, associated landscape and their setting in the landscape, an appropriate level of recording for structures of a well-known type for which existing documentation is in other respects adequate. |
