NEM market participants and their registered DUIDs

Description

Returns a mapping of NEM market participants (companies) to their registered Dispatchable Unit Identifiers (DUIDs), joined from the MMSDM PARTICIPANT and DUDETAILSUMMARY tables. Use this for corporate ownership analysis: rolling up generator output or bids from DUID-level data to the company level.

Usage

aemo_participants()

Value

An aemo_tbl with columns participantid, participantclassid (e.g. GENERATOR, LOAD, TRADER), name (company name), duid, stationid, regionid, dispatchtype, schedule_type. Rows are one per participant-DUID combination. If MMSDM is unreachable, returns an empty table with a warning.
