From 1st June 2024, you will need to authenticate API calls to the Connected Data Portal by supplying an API Token. Information on creating and using API Tokens can be found on the API Guidance page.
Data Groups
This group includes data relating to connections to the distribution network, such as the Embedded Capacity Register, low carbon technology, new connections and smart metering data.
This data group includes historic data and real time electricity demand
Data sets related to network flexibility requirements and zones, trades, procurement and dispatch information.
Innovation is core to our business strategy. We always seek to find better ways of working. We have adopted many innovative ideas into day to day operations that improve the efficiency and effectiveness of the way we deliver our services to customers.
Information and data related to network assets and system operation; for example the various Long Term Development Statement tables.
Looking and planning further ahead, and doing so in a strategic and cost-effective manner, is key to achieving National Grid’s vision of being at the heart of a clean, fair and affordable energy future. The data in this section provides insights into assumptions for future demand growth under various scenarios (DFES), network constraints and solutions identified over a 10-year period (NDP), and network investment decisions following cost benefit analysis and flexibility procurement, where applicable (DNOA).
In areas where there are multiple complex constraints affecting a number of customers over a long time period, an Active Network Management (ANM) system will be implemented. Distributed control systems continually monitor limits on the network and...
Busbar Node Codes used in the presentation of system data including locational Area and voltage connected.
The Common Information Models (CIM) provide a complete and consolidated view of our network assets and their connectivity. The models bring together a huge range of datasets from different types of energy network infrastructure equipment, sensors...
This data set contains the electrical parameters for circuits operating between 132kV and 6.6kV.
Location of NGED Distribution Substations (Easting / Northings)
Primacy - Data exchange between NGED DSO and NG ESO. Highlights potential risk of conflict within Flexibility market.
All DNOs are required by licence condition to comply with Ofgem’s Data Best Practice (DBP) Guidance. The DBP Guidance was updated by Ofgem on 7th August 2023, and the DBP Guidance now requires DNOs to openly publish Aggregated Smart Meter...

The Network Development Plan (NDP) represents the second step in the network investment planning process, which uses forecasts to analyse and identify future network constraints. The purpose of the NDP is to outline how National Grid Electricity...
The GSP Technical Limits dataset provides a view of the current technical power limits for the National Grid Electricity Distribution GSPs. This is aligned with Appendix G, so when these datasets are combined, it should provide a comprehensive...
