Download AEMO NEM dispatch price, demand, and interconnector flow data from NEMWeb's public file feed

Steps
Recognize NEMWeb is an unauthenticated static file server, not a queryable API — browse nemweb.com.au/Reports/Current/ for live report folders.
Pull 5-minute dispatch data from DispatchIS_Reports (regional reference price, demand, interconnector flows, constraints).
Pull trading interval summaries from TradingIS_Reports and historical demand from HistDemand.
Download and unzip the CSV files, stripping AEMO's embedded header/footer rows before parsing since a single ZIP can bundle multiple datasets.
For data older than the short retention window on Current, switch to the Archive folder or MMS Data Model historical extracts.
Known gotchas
The Current directory retains only recent files (on the order of a couple of days) — build a scheduled poll-and-archive job if you need continuity.
Don't confuse this public static feed with AEMO's separate authenticated REST API portal at dev.aemo.com.au (for accredited participants submitting bids/DER registrations/settlement data) — different system, different auth model.
CSV files are not clean single tables; multiple report types can be concatenated in one file with repeated header rows.
