Methodology
| Name | Category | Description |
|---|---|---|
| National Grid | Energy and Infrastructure | This dataset shows the approximate location of the national electricity transmission network, including towers, sub-stations, overhead lines and cables, which are used in high voltage (above 132kV) electricity transmission. For electricity distribution data, please contact the distribution company for your area. |
| Petroleum Exploration and Development Licences | Energy and Infrastructure | Petroleum Exploration and Development Licences give permission to search for and develop onshore oil and gas resources. |
| Power Stations | Energy and Infrastructure | This dataset shows the locations of all power station in England and Wales. |
| Solar Renewable Energy Sites | Energy and Infrastructure | The Renewable Energy Planning Database (REPD) map tracks the progress of renewable electricity over 150kW through the planning system across the UK. It provides as accurate and comprehensive a snapshot as possible of projects. The information in this Renewable Energy Planning Database is gathered from the separate planning authority databases throughout the UK. This is a subset of that data that consideres only projects with a stated technology type of 'Solar Photovoltaics'. |
| Wind Renewable Energy Sites | Energy and Infrastructure | The Renewable Energy Planning Database (REPD) map tracks the progress of renewable electricity over 150kW through the planning system across the UK. It provides as accurate and comprehensive a snapshot as possible of projects. The information in this Renewable Energy Planning Database is gathered from the separate planning authority databases throughout the UK. This is a subset of that data that consideres only projects with a stated technology type of 'Wind Onshore' or 'Wind Offshore'. |
| Other Renewable Energy Sites | Energy and Infrastructure | The Renewable Energy Planning Database (REPD) map tracks the progress of renewable electricity over 150kW through the planning system across the UK. It provides as accurate and comprehensive a snapshot as possible of projects. The information in this Renewable Energy Planning Database is gathered from the separate planning authority databases throughout the UK. This is a subset of that data that consideres only projects with a stated technology type other than 'Solar Photovoltaics', 'Wind Onshore' or 'Wind Offshore'. |
| COMAH Establishments | Energy and Infrastructure | This dataset provides details of establishments that are covered by the Control of Major Accident Hazards (COMAH) Regulations 2015. There are two types (tiers) of establishment which are subject to COMAH, known as 'Upper Tier' and 'Lower Tier' depending on the quantity of dangerous substances they hold. Upper Tier establishments have additional requirements are placed upon them as they hold greater quantities of dangerous substances. The dataset also indicates the reach of the Public Information Zone (PIZ) as a buffer for each site which are used by site operators to manage risks in the unlikely event an accident occurs. |
| Shrink-Swell Clays | Ground Stability | Shrinking and swelling of the ground (often reported as subsidence) is one of the most damaging geohazards in Britain today. This ‘shrink–swell’ behaviour is controlled by the type and amount of clay in the soil and by seasonal changes, related to rainfall and local drainage, in the soil moisture content. |
| Running Sands | Ground Stability | Some rocks can contain loosely packed, sandy layers that can become fluidised by water flowing through them. Such sands can ‘run’, removing support from overlying buildings and causing potential damage. |
| Compressible Ground | Ground Stability | Some types of ground may contain layers of very soft materials like clay or peat. These may compress if loaded by overlying structures or if the groundwater level changes, potentially resulting in depression of the ground and disturbance of foundations. |
