2 to 14 days ahead generation availability aggregated by Balancing Mechanism Units (UOU2T14D) stream

This endpoint provides a forward view of availability (also referred to as Output Usable 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.

This endpoint has an optimised JSON payload and is aimed at frequent requests for the data.
