This data has been prepared for both of Scottish and Southern Electricity Networks regions and will give you information about the local network to allow the analysis required to ensure a safe and secure supply when self identifying POCs.

This data and the user guidance for each of our network regions are accessed below. 

We strive to make this data accurate to assist you in designing your own connections. However, there may be changes in the network since the last update or there may be a query about certain data.

SEPD & SHEPD – NeRDA Opengrid Dashboard

The Near Real-time Data Access (NeRDA) Portal contains EHV/HV datasets from the Supervisory Control and Data Acquisition (SCADA) system, LV datasets from LV Monitoring devices, and Load modelling data. There are two ways to access the data using the NeRDA Portal: navigating to and around substations within the Portal itself or via Application Programming Interface (API) Access.

A “NeRDA Data Extraction Tool” is available from the NeRDA Opengrid Dashboard (available from the SSEN Distribution Data Portal), and it includes a user guide. This “NeRDA Data Extraction Tool” is to be used in conjunction with the above Transformer Rating and Loading Tools for both SEPD and SHEPD distribution areas.
