AEMO WA Market Data Public Feed

The Western Australian equivalent of NEMWeb, covering the Wholesale Electricity Market that AEMO operates separately from the NEM. Confirmed anonymous and live on 2026-07-27: GET https://data.wa.aemo.com.au/public/ returned HTTP 200 with directory listings for market-data, public-data, outages, advisories, infographic and INF, and GET /public/market-data/ returned HTTP 200 exposing capo, dsp, mt-pasa, outages, st-pasa and wemde subdirectories — the WEM Dispatch Engine outputs, short and medium term PASA, demand side programme and capacity data. Like NEMWeb it is an open HTTP file tree rather than a REST API, and like NEMWeb it needs no key, account or licence.
