Need network information?

We can help you get the insight and data intelligence you need about our network.

Powering network data

We understand the importance of network data to our customers.

We're committed to providing accessible network information that enables our customers - and other key stakeholders - to make informed decisions about their electricity supplies now and in the future.

From our Generation and Demand Heat Maps to our Distribution Future Energy Scenarios (DFES) data tool, we're making it easier for our customers to get the insight they need.

Distribution Future Energy Scenarios

A low-carbon economy, new technology, digitisation and changing customer needs are driving unprecedented change in the way energy is created and used bringing with it smarter, more flexible networks. We have a part to play in planning for the future and enabling a low carbon future that supports economic growth. As part of our Distribution Future Energy Scenarios (DFES), we've created, with Leeds Open Date Institute, an interactive online tool that uses geospacial maps to show how different influences can change electrical demand and generation on our network now and in the future.

AutoDesign

Our online AutoDesign tool gives an unprecedented level of insight and helps make it quicker and easier for you to get connected. By showing the best locations to connect to our Low Voltage (LV) network and providing free budget estimates in just minutes, it helps our customers, including local authorities, installers, and businesses planning new charging infrastructure, make informed decisions about the best locations to install Electric Vehicle (EV) chargers. Our tool helps support and accelerate the road to decarbonisation and achieving Net Zero.

Long-Term Development Statement

Our Long-Term Development Statement (LTDS) contains network information which can be used when assessing the feasibility of connections to our network. It helps existing and future customers to assess opportunities available for development projects that need new or additional connections.

Demand Heat Map

Our Demand Heat Map can give you an insight into our network’s capability to connect large-scale developments to major substations. Our Heat Maps are available in webview. We also can provide downloadable network data to support customers and provide enhanced data including Appendix and Statement of Works.

Generation Heat Map

Our Generation Heat Map can give you an insight into our our network’s capability to connect large-scale generation developments to major substations at Extra High Voltage and High Voltage. Our Heat Maps are available in webview. We also can provide downloadable network data to support customers and provide enhanced data including Appendix and Statement of Works.

System Wide Resource Register

Our System Wide Resource Register provides information on connected resources and network requirements. This includes generation and storage resources (≥1MW) that are connected, or accepted to connect, to our network and information on flexibility services that are being provided by connected resources including flexible demand. Updated monthly using nationally agreed formats set by the Open Networks project, it will expand in the future to include network reinforcements information needed to provide connections. In line with the Utility Act and Network Codes, some data is currently protected and not visible. Network Codes modification proposals are being progressed to enable all data fields to be published in the future.

Contracted Capacity Register

Our Contracted Capacity Register, which is updated monthly, provides information such as agreed capacity, installed capacity and generation type relating to generators (sized at 72kVA or above) which are either connected to our network or have accepted a connection offer.
