WEM — Wholesale Electricity Market
Western Australia's South West Interconnected System — a separate market operator and rules, redesigned in October 2023.
Reformed market (Oct 2023)
The new WEM moved WA to modern security-constrained economic dispatch with a real-time market and reserve capacity mechanism.
~1-day-latency SCADA
Facility SCADA publishes as a monthly batch file regenerated daily — no live 5-minute feed like the NEM, so 'recent' means yesterday.
No site-level official forecast
WA AEMO publishes no per-facility UIGF equivalent, so there is no official forecast overlay to compare against — honest by design.
Onboarding in progress
The facility registry is connected; sites go live for browsing and favorites as the ingest pipeline onboards them.
Registered fleet
Every registered utility wind & solar site in the market registry — wind in blue, solar in amber.
Fleet aggregate — forecast vs measured
Per-instant sum of the latest day-ahead forecast across onboarded sites, against the summed measured output. Coverage counts sites contributing at each point.
