Primary Substation Electricity Supply Areas

Shapefiles containing the geographical representation of the Primary Substation Boundaries for SEPD & SHEPD. The primary substation areas are formed from Voronoi polygons based off the point locations of all the secondary substations fed by a given primary substation. This means that every point in a polygon is closest geographically to the assigned secondary substation. The secondary substation polygons are then dissolved with respect to the primary they are connected to form the primary supply areas.

Generation Availability and Network Capacity

Our Generation Availability and Contracted demand map for both north and south. Our map provides an indication of the networks capability to connect large-scale developments to major substations. Accompanying the map, the heat map spreadsheets for both of our network regions provides Grid Supply Point (GSP) details, GSP and substation transformer ratings, Fault level information, and contracted and quoted generation projects at each GSP.

SSEN Distribution Data Roadmap

The SSEN Data Roadmap serves as the strategic plan outlining the key milestones related to data provision and management. It provides a structured path for implementing data sets and achieving data strategy goals.

The Data Roadmap promotes open collaboration and transparent data sharing with stakeholders. By outlining clear milestones and objectives, it creates a shared vision with stakeholders which encourages active involvement and feedback, where insights and requirements can be openly addressed. This ensures stakeholders are well informed about the data journey, promoting trust and cooperation in achieving common data-related goals.

GSP Technical Limits

This dataset provides the approved commercial technical import and export limits for each Grid Supply Point (GSP) where formal technical limits have been assessed and accepted. For every listed GSP, the dataset sets out the seasonal limits that apply, showing how much power can be imported to or exported from the distribution network at different times of the year.
Customers can use this dataset to:
- Understand the network capacity constraints at specific GSPs.
- Support connection applications, feasibility studies, and planning activities.
- Identify where seasonal variations may influence project design or operational decisions.
This dataset forms part of our commitment to network transparency, helping users make informed choices based on the technical capabilities of each GSP.

Flexibility Markets – Long Term Bidding

Our long-term bidding rounds typically involve flexibility requirements from our Distribution Network Options Assessment (DNOA) process that determines flexibility needs from our Extra High Voltage (EHV) network in the next three years. In addition, we include High Voltage/Low Voltage requirements at year ahead. This is normally flexibility needs for reinforcement deferral, or where our Control Rooms require flexibility for outage planning.

SHEPD Long Term Development Statement

The Long Term Development statements provide information for anyone connecting to our distribution system at extra high voltage (EHV) level (including HV busbar of primary substations). It is designed to help to identify and evaluate opportunities for entering into arrangements with us relating to use of system or connection.  Our statements include the following:  network data; the likely development of our distribution system; plans for modifying the distribution system; and identification of parts of the distribution system that are likely to reach capacity limit in the next years.  A long term development statement is available for each of our distribution network areas in central southern England and northern Scotland.  Each statement has two sections, a summary (Part 1) and a detailed section (Part 2) both of which are available for download below.

Embedded Capacity Register

The Embedded Capacity Register (ECR) has been developed to provide better information to electricity network stakeholders on connected resources and network requirements. Each Distribution Network Operator (DNO) will host a register which will provide accessible information at a local and national level. The register uses a format agreed through the Energy Networks Association's Open Networks project, an industry initiative aimed at transforming the operation of energy networks and delivering a smart grid. 

Our register provides information on generation and storage resources (>=50kW) that are connected, or accepted to connect, to the electricity distribution networks owned and operated by us and it will be updated on a monthly basis. The register also includes information on the flexibility services that are being provided by connected resources, assisting to control or schedule demand and/or generation to reduce network constraints.

Flexibility Dispatch Report

The Flexibility Dispatch report is a weekly ahead flexible services utilisation report which provides a summary of the dispatch instruction for both SEPD and SHEPD licence areas.  The data identifies the area where the service products will be dispatched and how much capacity will be instructed from different flexibility providers. The Flexibility Dispatch report is intended to give our stakeholders an insight about the future usage of flexibility services and help them to better understand the potential opportunities for flexibility utilisation. The dataset also contains historical dispatch information dating back to 2023.

Smart Meter LV Feeder Usage

Smart meter LV feeder half hourly usage data is collected directly from smart meters in homes and businesses and anonymised through aggregation to no less than 5 properties through SSEN’s smart meter adapter. There is a postcode and LV Feeder Dataset ID lookup to provide the aggregated half hourly consumption data in Wh (combined primary and secondary active import Wh), from the relevant secondary transformer and low voltage feeder IDs with a total count of smart meters.
Please note that the aggregated half-hourly data provided via our Open Data Portal is sourced from smart meters. Smart meters, their performance, and the data stored within them are the responsibility of the energy suppliers who install them at customers’ premises. There are some known and potential unknown issues within the data, and while we make reasonable efforts to ensure the accuracy of the smart meter data retrieved, we do not accept responsibility or liability for its accuracy, completeness, or any loss arising from reliance on this dataset.

Isle of Wight Active Network Management

Isle of Wight ANM Live provides real time information on the status of the ANM systems. It has been designed to help ANM generators understand when the system is operating as expected and when there may be faults.  

Isle of Wight Electricity Demand: The graph shows the live demand for electricity as a proportion of the winter peak demand. The peak winter demand is a static figure that is reviewed annually by Southern Electric Power Distribution (SEPD)  

Isle of Wight Renewable Generation: The graph also shows the total live Isle of Wight renewable generation as a proportion of the total renewable capacity.  The generation can be greater than the live demand, which means the excess will be exported to the English mainland.  The additional renewable generation attributable to the Isle of Wight ANM system is shown as a proportion of the total renewable generation.  The total renewable generation does not include the micro generation (<50kw) installed on the network.

NeRDA Opengrid Dashboard

The Near Real-time Data Access (NeRDA) Portal aims to examine how near real-time energy demand and usage data can be best used by stakeholders. The data identifies areas where flexibility could be used or where network reinforcement will be needed. NeRDA is intended to provide open data and share electricity demand estimates with stakeholders. The Portal currently contains EHV/HV datasets from SCADA, 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 API Access.
