Berrington 11Kv Primary Transformer Flows
The Long-Term Development Statement (LTDS) provides essential information to assist current and prospective users of National Grid Electricity Distribution’s (NGED) network in identifying and assessing opportunities for new or additional use of our distribution system. More information can be found at [National Grid – Long Term Development Statement](https://commercial.nationalgrid.co.uk/our-network/long-term-development). The LTDS Capacity Heatmap contains data relating to each of NGED’s four licence areas, covering 132kV at Grid Supply Points down to 11kV or 6.6kV at primary substations. This dataset is the second stage in NGED’s transition to publishing the LTDS in CIM and JSON format, supporting [Ofgem’s LTDS Reform](https://www.ofgem.gov.uk/decision/long-term-development-statement-direction) to improve transparency and interoperability across GB networks. In time, it is expected to supersede the [LTDS Tabular Model](https://connecteddata.nationalgrid.co.uk/dataset/ltds-tabular-model). ## Scope of Current Release The Capacity Heatmap provides a standardised, geographically referenced dataset showing available capacity across NGED's four licenced networks. It includes information on available demand (import) and generation (export) capacity at substations, together with location data and supporting metadata. The dataset may also include information on network constraints, transformers, circuits and connected generation, demand or storage assets, helping users understand network capability at a high level. ## Purpose and Benefits The Capacity Heatmap is designed to help customers, developers, local authorities and other stakeholders quickly identify areas of the network with available capacity for new connections. By providing pre-calculated capacity information in a consistent, machine-readable format, it enables users to undertake initial assessments and location screening without requiring detailed power system modelling expertise. ## Relationship to Other Publications The Capacity Heatmap forms part of the Long Term Development Statement (LTDS) and complements the more detailed network information provided through the wider LTDS. While the LTDS includes network asset data, development plans and detailed grid models suitable for technical analysis, the Capacity Heatmap provides a simplified and accessible view of network capacity that can be readily used for planning and site screening activities. For National Grid Electricity Distribution, the Capacity Heatmap includes the same demand and generation headroom information currently published through our Network Opportunity Map Headroom dataset, providing a standardised view of available network capacity at substations. The LTDS Capacity Heatmap builds on this by adopting a common industry data structure and publication format, helping users access, compare and analyse capacity information consistently across Great Britain's electricity distribution networks.

Enabling a clean, fair and affordable energy future through open data
# Overview This dataset contains information on what we will look to put forward in our upcoming trades, with the aim to provide more visibility ahead of the actual trade opportunities. For general Constraint Management Zone (CMZ) information and overall requirements, please go to the _[Flexibility – Forecasts](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-forecasts)_ page. National Grid facilitates its flexibility procurement activity through its online portal, _[Market Gateway](https://marketgateway.nationalgrid.co.uk/)_. Flexibility Service Providers (FSPs) seeking an award to deliver flexibility services should register on the Market Gateway and complete the pre-qualification requirements to enable their eligibility to enter into flexibility Trades. Pre-qualification is always open and can be completed at any time. Further guidance on this process is available _[here](https://flexiblepower.wpdserv.net/downloads/1121)_. Any questions should be sent to _[nged.flexiblepower@nationalgrid.co.uk](mailto:nged.flexiblepower@nationalgrid.co.uk)_. # Data _[HV – Long Term Trade Parameters.csv](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-trades-data-and-results/resource/a45f323a-c0f6-4a2c-bdc2-bb442ec97c42)_ includes information for Scheduled Availability Operational Utilisation - Day Ahead Notice and Operational Utilisation - 15min Instruction flexibility products within HV Zones, such as peak MW requirements (min, max), ceiling prices, and delivery windows (dates, times, days required). _[LV – Long Term Trade Parameters.csv](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-trades-data-and-results/resource/47f87588-f05d-4a44-83ca-c1f90b101cdc)_ contains information for all zones where Scheduled Utilisation is available.
