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).
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...
Import, Generation and Demand values at half hourly granularity per transformer for the previous two years from 31st March 2019.
When launched, Electric Nation was one of the world's largest home smart charging trials with nearly 700 EV owners taking part in the 18-month trial. Between them, our trial participants provided data for more than 2 million hours of car charging...
Make and Break fault level data from the 10 Fault Level Monitors installed as part of the FlexDGrid Low Carbon Networks Fund innovation project
Voltages at half-hourly granularity for all transformers at GSP, BSP & Primary level across South West, South Wales, East Midlands & West Midlands, between April 2019 - April 2021.
The connection queue will be provided when the Connection Reform queue has been confirmed to NGED by NESO in December 2025.
The relationship from every node to any branch in the network model is provided within the sensitivity factor tables. These are calculated using PSS/E load flow software and are used to determine the effect of increasing net demand at each node to...
All Standard, Flexible and Curtailable connections are categorised into Wind, Photovoltaic, Battery or Other dependant on their fuel type within the application. An annual half hourly profile is provided for each fuel type. Please see the...
The net power flow through each GSP, BSP and primary substation. For each substation the data is presented against each relevant node in the network model to reflect the intact topology. Statistical data cleansing (identification and replacement...
The derived net power flow through each branch. This is calculated using the substation loading and sensitivity factors for each substation’s node(s) to each branch. The sign associated to this load is based on the From Node and To Node. Please...
