42watts forecasts NEM spot prices 24 hours ahead at five-minute resolution — as a calibrated correction over AEMO's own P5MIN and pre-dispatch forecasts. Quantiles q10 through q90, not a single number.
A five-minute loop that turns AEMO's raw dispatch data into a calibrated view of the next 24 hours — with provenance at every step.
Every P5MIN, PREDISPATCH and DISPATCHIS file AEMO publishes lands immutably in R2, parsed at five-minute cadence with a full audit trail.
Three tiered models — NEAR, MID and FAR — learn the error in AEMO's own forecast and emit calibrated quantiles for every 5-minute interval.
Quantiles and correlation-preserving scenario paths stream from the /v1 API — each row traceable back through its ingestion run to the source artifact.
A separate model per horizon, blended most-recent-issuance-wins at every 5-minute target interval.
The same 24-hour distribution, turned into a plan. Describe what you drive and store, and 42watts schedules every charge and discharge into the cheapest five-minute intervals — then shows what you'd have paid following AEMO instead.
Pick from an Australian catalog of EVs and home batteries — or enter custom specs. We derive the kWh and kW from your weekly distance and capacity, and never charge the car while it's away from home.
Keep separate plans for weekdays, weekends and seasons. Each runs only on the days you choose, at the NEM time you pick — charging into the cheapest intervals and discharging into the priciest across the next 24 hours.
Each morning you get today's charge and discharge windows by email, with yesterday settled against actual prices — per device, and the dollars saved versus following AEMO's forecast.
