The dissemination Platform for Operational Data describes the data from operational assets that can be obtained from ORE Catapult. It includes various filtering options and details of the measures and data points available.

These datasets provide the approximate location of the national electricity transmission network. They are for indicative purposes only. They can only be used for emergency and land use planning and cannot be used for commercial purposes. They are owned by National Grid and you are required to acknowledge us in your product or application using "© National Grid UK".This data is supplied on a best-effort basis only, using available information as documented at the time by the transmission network operators. While every effort is made to make sure the information is accurate and up-to-date, we do not accept any liability for any direct, indirect, or consequential loss or damage of any nature--however caused--which may be sustained as a result of reliance upon such information. The datasets contain electricity transmission data only. For electricity distribution data, please contact the distribution company for your area. You can find your local distribution company by going to the Energy Networks website. If you are planning to undertake any ground works, please visit the Line Search website or contact the National Grid Asset Protection team at least 14 days in advance. All datasets are accompanied with Gemini 2.2 metadata.

This endpoint provides a forward view of availability (also referred to as Output Useable data under the Grid Code) for generation and interconnector capacity, accounting for planned outages covering availability data from 2 days ahead to 14 days ahead; it is aggregated by National Grid Balancing Mechanism Units (NGC BMUs). In the context of this report, BMUs can be considered as generating units. Elexon BMUs differs from NGC BMUs by including a prefix e.g. 'T_'. The mapping between NGC and Elexon BMUs can be retrieved via reference data API endpoints.
