- Latest analysis tranche reference: T9A # Overview We are looking to mitigate a range of constraints across multiple voltage levels on the network. As they involve different methods of assessment and operation, our Constraint Management Zones (CMZs) are split into __HV Zones__, covering constraints at 11kV and above, and __LV Zones__, covering constraints on our 230/400V networks. Our HV Zones have __Scheduled Availability, Operational Utilisation - Day Ahead__ product available. In LV Zones we are looking to procure __Scheduled Utilisation - Specific Periods__ services from providers connected at lower voltages. More information on all products can be found in our latest [Procurement Statement](https://www.nationalgrid.co.uk/distribution-flexibility-services-reporting). Information on all the constraints we have assessed can be found in the [Distribution Network Options Assessment (DNOA)](https://connecteddata.nationalgrid.co.uk/dataset/distribution-network-options-assessment-dnoa). We undertake flexibility analysis on a regular basis, and we will keep updating this data in line with the latest tranche of analysis. # Data The data covers overall zonal requirements, including locational data. Full information on HV Zones is available in the _[Flexibility_Database_and_Queries.zip](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-requirements/resource/196bcfb9-0b12-478b-a1c2-173a06655478)_. Some useful information has been extracted into csv data files, and the SQL queries used for this are available within the compressed zip file. However, some reports below have been manually edited to improve readability and reduce the number of files, so running queries may not always produce an exact match. _[OVERVIEW_All_Zones.csv](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-requirements/resource/c70e485e-7715-4e98-87d8-46fdd1684a21)_ provides a list of all Constraint Management Zones (CMZs), both HV and LV, which are or will shortly be open for procurement. This file contains some basic information such as the main product and service type in the zone, and provides an indication of how many zones we have active in each Licence Area. __WHERE__ Information on where we require flexibility services is contained in the following Postcodes and Polygons files, for combined HV and LV zones. These are updated with each tranche of analysis as zones change and as we improve our data accuracy over time. - _[WHERE_All_Postcodes.csv](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-requirements/resource/a9a0ddbf-117c-4b20-82cc-a3689d2422c9)_ - _[WHERE_All_Polygons.gpkg](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-requirements/resource/3ade7e88-44e4-430a-9f43-3eec0e6eab0a)_ As with all geographic data, the Postcodes and Polygons are indicative only and final mapping of assets to zones will be carried out on an asset by asset basis following their registration on [Market Gateway](https://marketgateway.nationalgrid.co.uk/). The list of postcodes is deliberately broad, to avoid excluding assets from participation. Wider work is being carried out to improve the accuracy of this data. __HOW MUCH and WHEN__ We look to procure Scheduled Utilisation - Specific Periods services within our LV Zones, which is a simple and less targeted product compared to Scheduled Availability, Operational Utilisation - Day Ahead. _[HOW_MUCH_and_WHEN_LV_Zones.csv](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-requirements/resource/3e2659ed-9df7-4d5f-9410-34363df3b671)_ provides information on how much (minimum and maximum kW) we look to procure, the maximum price we can pay (ceiling price), and the delivery periods, which are the same across all zones. The minimum kW value relates to a minimum we would look to procure in order to defer reinforcement, and NOT to a minimum capacity of an asset. If this is not met, we may decide to progress reinforcement and not award flexibility services. The forecasts for our HV zones, such as the estimated peak capacity (MW), energy (MWh), and the ceiling prices, are presented in _[HOW_MUCH_HV_Zones.csv](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-requirements/resource/4e0e6ddf-9721-4c19-bc68-274eeb460381)_. Moving to ceiling prices means that the maximum price is now linked with the volume of flexibility required, therefore in most cases ceiling prices will decrease over time as the amount of flexibility required generally tends to grow. As the requirements for our HV Zones are more complex, granular, and targeted, information regarding when we may need flexibility services is presented in two forms: - a simplified, monthly breakdown of potential needs over the years (_[WHEN_HV_Zones.csv](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-requirements/resource/44e2cdbe-0f25-4205-a8ff-5d4bb66f2f57)_), which should provide an overview of needs over time, and - as half-hourly peak MW profile data in _[WHEN_HV_Zones_MW_Profiles.csv](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-requirements/resource/266f996e-c51a-4bfe-98bb-8816fcf9e8ef)_ for a year; full profile data is available in the database. __When procurement opens, each Trade Opportunity will contain details of final volumes and delivery periods. Trade Opportunity information is available on the _[Flexibility – Trades Data and Results](https://connecteddata.nationalgrid.co.uk/dataset/flexibility-trades-data-and-results)_ page.__ ## Disclaimer While every effort has been made to ensure its accuracy, the data may contain inaccuracies, omissions, or may be out of date.

- 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 data. Importantly they also gave us first hand feedback on what it is like living with an Electric Vehicle in the real world and how they found the smart charging experience. The results from Electric Nation have global significance and allow electricity distribution network planners to replace high level axioms with statistically robust facts. The lessons from this project will greatly assist local electricity networks in accommodating home Electric Vehicle charging whilst ensuring that drivers always have the ability to charge when they need to. Electric Nation was a 3 year project, which was funded using the National Innovation Allowance.

- The Net Zero South Wales 2050 innovation project was undertaken as a partnership between Regen, National Grid Electricity Distribution (NGED) and Wales and West Utilities (WWU) with funding from the Network Innovation Allowance (NIA) programme. The main objective of the project was to create integrated distribution future energy scenarios (DFES) for the gas and electricity networks in South Wales and, as part of this, to develop a new methodology for conducting cross-vector scenario forecasting at a regional level. The project also looked to provide insights into how South Wales might transition to a net zero future under three net zero scenario pathways; High Electrification, Core Hydrogen and High Hydrogen. The main output of the project is a DFES projection dataset provided to NGED and WWU to inform network planning and investment. The dataset covers key technologies, both demand and supply, that might be expected to connect to the gas and electricity distribution networks under the three scenario pathways and covers each year from 2020 to 2035, and then five yearly intervals between 2035 and 2050. Projections are provided at geographic levels relevant to each respective network, Electricity Supply Areas (ESAs) and Gas Supply Areas (GSAs). ## Disclaimer This dataset is provided solely for reference purposes.

- The data sets below contain information on locations, volumes and value of flexibility we are looking to procure following the latest analysis – Tranche 7A. We are looking to mitigate a range of constraints across multiple voltage levels on the network. As they involve different methods of assessment and operation, our Constraint Management Zones (CMZs) are split into **HV Zones**, covering constraints at 33kV and above, and **LV Zones**, covering constraints on our 6.6kV and 11kV networks. Our HV Zones have Secure and/or Dynamic products available, and, where applicable, Sustain (also referred to as HV Sustain). In LV Zones we are only looking to procure Sustain services (also referred to as LV Sustain) from providers connected at low voltages (LV customers). Sustain is the same product across both LV and HV zone, with the same parameters and customer eligibility; HV or LV is only to differentiate between the constraint levels. Once you register your assets on [Market Gateway](https://marketgateway.nationalgrid.co.uk/), they will be automatically matched with any suitable CMZ. More information on all products can be found in our latest [Procurement Statement (April 2023)](https://www.nationalgrid.co.uk/downloads-view-reciteme/631494). Information on all the constraints we have assessed can be found in the [Distribution Network Options Assessment (DNOA)](https://connecteddata.nationalgrid.co.uk/dataset/distribution-network-options-assessment-dnoa). # LV CMZ Data: Information on **WHERE**, **WHEN** and **HOW MUCH** flexibility we are looking to procure to manage our 6.6kV and 11kV networks can be found in [FSP_Information – CMZ_LV_INFORMATION Table.csv](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-tranche-7a/resource/bac649c6-3629-4657-82c8-eb7b707ec16d). For all our LV zones, we are looking to procure **Sustain**, **demand turn down** services only. The above provides the list of zones, how much flexibility we are targeting (Maximum kW column), the maximum price we can pay (Ceiling Price column), and when we require the service to run (dates, delivery periods, days of the week). # HV CMZ Data – Overall requirements As the requirements for our HV Zones are a lot more targeted and complex, these are covered into a number of separate files, each focusing on certain parameters. Overview information on **WHERE** we are looking to procure flexibility can be found in [FSP_Information – CMZ_INFORMATION Table.csv](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-tranche-7a/resource/6ce15d38-1bf2-4139-a24b-d25afebbbcd3). This provides basic, overview information containing the list of zones, main flexibility product we are after, and the service type: e.g. demand turn down (DTD) / demand turn up (DTU) / generation turn down (GTD) / generation turn up (GTU). The geographical information section provides more details on where we require services in each zone. Each zone is broken down into Primary Substations, listed in [CMZ_Primary_Substation_List.csv](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-tranche-7a/resource/68fcd7f9-22d4-4bb0-bac1-c5794bf6e829). An indication of **WHEN** and **HOW MUCH** flexibility we expect to require is available in two separate files.

These profiles will vary throughout the year, as network loading changes, and the peak MW represents the capacity (peak power) we will likely look to procure to ensure our networks remains compliant. For MWh volumes, the total energy we are looking to procure, [FSP_Information – MWh_VALUES Table.csv](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-tranche-7a/resource/882bbc26-25db-49a3-b0f3-76d3172889b5) provides further details on how much energy in total we expect to procure, broken down into monthly volumes. # HV CMZ Data – Long Term and Sustain requirements In certain HV zones we are looking to secure a certain amount of flexibility service further ahead. We are providing, alongside the overall requirements within each CMZ, further information on how much and when we will look to procure further ahead, in our **Long Term Trades**, across the long term version of the core product and **HV Sustain**. This will only cover the HV zones where this is suitable / required, so some zones might not appear in this data. [FSP_Information – CMZ_LONG_TERM_INFORMATION Table.csv](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-tranche-7a/resource/1bc306e1-75a9-4a62-9cf1-4116c1acc8db) provides details of **WHEN** and **HOW MUCH** we are looking to cover in the Long Term trades with the core products (Secure and/or Dynamic). Each delivery window has a start date, end date, start times, end times, which days of the week we require, and the required capacities (Maximum kW). Where suitable, we are also using the Sustain product within HV zones to cover part of the overall requirement, to provide another market opportunity which is simpler and less targeted. [FSP_Information – CMZ_SUSTAIN_INFORMATION Table.csv](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-tranche-7a/resource/571057c8-ac7d-453e-95d6-a05da3d3f111) contains details on how much and when we would require the Sustain product within HV zones. The data is presented in the same format as the LV Zones, with the same parameters given the product itself is the same but used to support at a different network level. To help visualise the requirements, we have also prepared graphs showing the Long Term and Sustain requirements, which have been packaged into the [T7A_Long_Term_MW_Profile_Graphs.zip](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-tranche-7a/resource/18090108-80ac-403e-bf10-4294c940c599). # Other data sets **Geographical information** is available in the form of Postcodes data ([CMZ_Procurement_Postcodes.csv](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-tranche-7a/resource/642d5423-ce31-4c65-80a5-a6693970fe1a) and [CMZ_LV_Procurement_Postcodes.csv](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-tranche-7a/resource/bfa16d35-453a-4652-8e54-2b0a26ce36a2)) and [Polygons](https://connecteddata.nationalgrid.co.uk/dataset/constraint-management-zone-cmz-polygons) associated with each zone.

- This is the final of three National Grid Electricity Distribution (NGED) short data challenges! The aims of these challenges include: 1. Demonstrating the value in making data openly available 2. Increasing the visibility of some of the challenges network operators face 3. Increase the understanding of the different ways to tackle some of these problems 4. Providing high quality and accurate benchmarks with which to enable innovation and research This final challenge is a unique spin on the traditional missing data problem which considers different scenarios for missing data across the hierarchy of a distribution network (Primary up to grid supply point). Traditional missing data problems typically focus on an isolated time series and often require imputation approaches based on local measurements. In this challenge, we are asking participants to utilise monitoring data across the network (as well as weather and other publicly available data) to solve various missing data scenarios which extend the problem to situations where multiple connected substations may lose data. All the slides from the kick-off and other information can be found on the [LinkedIn group](https://www.linkedin.com/groups/9025332/) and the recording from the kick-off event will be uploaded shortly after the event.1Licence not specifiedabout 3 years ago
- This is the second of three National Grid Electricity Distribution (NGED) short data challenges! The aims of these challenges include: 1. Demonstrating the value in making data openly available 2. Increasing the visibility of some of the challenges network operators face 3. Increase the understanding of the different ways to tackle some of these problems 4. Providing high quality and accurate benchmarks with which to enable innovation and research This challenge aims to estimate the increased demand created on primary substations by the installation of electric vehicle (EV) chargers. High uptakes of EVs will cause more strain on the distribution networks, especially at the low voltage level where there is limited headroom for high demand technologies such as EVs. Unfortunately, the amount of EV chargers installed, and hence the potential extra demand on a network, may be unknown, even to a distribution network operator (DNOs). However, DNOs do monitor the demand at the substation level and this shows the aggregated demand from all connected appliances and, in addition, many DNOs do have example data for EV demand. The ask for this challenge is whether this information can be combined with other data to help predict the increased demand generated from EV chargers on a network.

- This is the data for the first of three National Grid Electricity Distribution (NGED) short data challenges! The aims of these challenges include: - Demonstrating the value in making data openly available - Increasing the visibility of some of the challenges network operators face - Increase the understanding of the different ways to tackle some of these problems - Providing high quality and accurate benchmarks with which to enable innovation and research Note all the slides from the kick-off and other information can be found on our LinkedIn group: https://www.linkedin.com/groups/9025332/ This initial challenge aims to understand how accurately high resolution features can be estimated given only information from lower resolution data. Specifically we are asking participants to estimate the highest peak value and lowest trough at a one minute resolution within each half hourly period given only half hourly measurements. This is an interesting problem to a distribution network operator as the spikes in demand can mean strain on their network. Such issues may become increasingly common, especially on the lower voltages of the network, due to the expanding use of lower carbon technologies such as electric vehicles, and heat pumps. However, monitoring can be expensive (especially in the long term) as it requires investment in additional storage, communications equipment and processing units.1Licence not specifiedabout 3 years ago
- The data sets contain geographic areas where we have identified (using the criteria described in the Call for Evidence) a potential need for strategic investment in our electricity network to enable ‘green recovery’ projects to proceed over the next 2 -3 years. The data contains areas that could benefit from these investments and are based on the distribution areas of the substations named on the map. The type of network reinforcement proposed in these areas varies but includes new or upgraded substations (ranging from smaller 11kV to larger 33kV and 132kV substations), as well as investment to upgrade the existing circuits (cables and overhead lines) connecting these substations to the wider electricity distribution network. Some of the projects will also create new high voltage assets and effectively bring the NGED network physically closer to areas where we know there is significant interest in green investment, but where the capacity of our network is more limited at present.1Licence not specifiedabout 3 years ago

- One element of our plan to accommodate electric vehicles on our network is to make use of existing capacity. We have reviewed this capacity at a street by street level using our local distribution substations. We assessed the available capacity at each site and have represented this as a generic level of EV charging capacity.1Licence not specifiedover 4 years ago
