supagridA DUID (Dispatchable Unit Identifier) uniquely identifies a generating or load unit in the NEM. Units are the building blocks of facility-level data in supagrid.
What is a DUID?
Each physical unit (e.g., a wind turbine, gas turbine, or battery inverter) that participates in the market has a DUID. A facility (station) can have multiple units; for example, a wind farm with many turbines might have one DUID per turbine or a grouped DUID for the whole farm.
Unit vs facility
- Facility (station) – A power station or site (e.g., "Smithfield Solar Farm"). Identified by
station_id. - Unit (DUID) – An individual dispatchable unit within a facility. Identified by
code(the DUID string).
Data at unit level
Time-series data (dispatch, SCADA, revenue, etc.) is typically at the unit (DUID) level. supagrid aggregates this where needed for facility or portfolio views. See AEMO variables for the fields available per unit.
