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.
