These maps show the potential area affected by noise from Grid or Primary Substations. Acoustic mitigation strategies that have already been applied to some substations are not reflected in the maps.Please take this into account when looking at individual sites.
\nPlease note this dataset is restricted, and if you would like to be considered for access, please contact: \"opendata @ukpowernetworks.co.uk\"
\nDevelopers and local authority planners should be aware that the responsibility to mitigate noise issues rests with the developer as the \u2018agent of change\u2019.
\nThere are three contours:
Distance (m) | Predicted Noise Level (dBA) | Complaints | Action |
| 40 | 44 | Likely from any new residential development | Please consult environment@ukpowernetworks.co.uk |
| 75 | 39 | Possible from any new residential development | Please consult environment@ukpowernetworks.co.uk |
| 135 | 34 | Not very likely |
\nQuality Control Measures include:\n
