A canonical market profile joining Western Australia's grid operation, distributed-energy adoption, population, production climate, tariffs, transition outlook and evidence condition.
The same endpoint can return the current operating series, a fixed edition, only material changes, the projective outlook or the source registry.

A frozen May 2026 baseline and transparent 2030 planning envelope for small-scale solar and distributed batteries in the public SWIS extent, with source lags, evidence limits and review triggers carried beside the range.
A reference edition for 246 local Western Australian energy markets: rooftop solar and battery adoption, household addressability, published network opportunities, and the operating record of an isolated grid. It makes one point plainly: SWIS is not one market.
Energy Policy WA has seven proposals out for consultation on how distributed energy data is collected, verified and shared across the SWIS, with submissions closing 18 August 2026. On a grid where rooftop solar has met up to 80.8 per cent of daytime demand, data quality is the operating margin.
AEMO's ten-year SWIS planning case, kept explicitly separate from observed operations: a 347 MW forecast surplus in 2028-29, a shortfall from 2029-30, and coordinated household batteries entering the capacity model.
A fixed reference edition connecting Australian product eligibility, distributed adoption, grid operation, realised storage-market capture, regulated tariffs and forecast accountability, with quality declarations and verification boundaries published beside the evidence.
