National Grid’s Distribution System Operator (DSO) has unveiled its most extensive release of network data to date. This initiative aims to assist customers and developers in evaluating the feasibility and cost-effectiveness of connecting new local energy projects more efficiently. The dataset encompasses all of National Grid Electricity Distribution’s Grid Supply Points (GSPs), offering detailed insights for 2,541 substations and 6,471 branches over the past year. This release makes over 150 million individual data points publicly accessible, marking it as the most comprehensive dataset the DSO has provided so far.
This data aims to empower new customers to independently assess potential curtailment before applying for a flexible connection via the National Grid Electricity Distribution’s Active Network Management (ANM) system. Additionally, it is useful for understanding the commercial and technical implications once a connection offer has been made. Phil Moseley, Head of System Models and Data at National Grid DSO, stated that this release is a significant advancement in providing the necessary information for customers to make informed decisions when connecting to the network, highlighting the importance of transparency in expediting the energy transition and delivering better consumer prices.
According to National Grid DSO, this dataset is intended for a diverse range of stakeholders, from developers of large-scale generation and storage projects to those working on smaller, local energy schemes. By offering insights into historical and modelled network behaviour, the company believes customers can identify viable locations for flexible connections and anticipate potential constraints on export or import.
To facilitate practical use of the data, a newly established curtailment team within the DSO has developed comprehensive guidance on navigating, interpreting, and applying the dataset. This guidance clarifies the assumptions underlying the modelling and ANM systems, ensuring the information is both accessible and reliable.
The dataset is now available via the National Grid website.
