Regional electricity demand

Description

Returns 5-minute regional demand from DISPATCHREGIONSUM. Three demand measures are supported, aligned with AEMO's Demand Terms taxonomy:

Usage

aemo_demand(
  region,
  start,
  end,
  measure = c("operational", "operational_less_snsg", "native"),
  intervention = FALSE
)

Arguments

region	NEM region code. Vector accepted.
start, end	Window (inclusive), character or POSIXct.
measure	One of "operational" (default), "operational_less_snsg", or "native".
intervention	Logical. Default FALSE filters to market pricing runs.

Details

• "operational" (default): TOTALDEMAND, the grid-measured demand met by scheduled and semi-scheduled generation plus net interchange. This is the quantity AEMO dispatches.

• "operational_less_snsg": TOTALDEMAND minus small non-scheduled generation (SS_SOLAR_UIGF + SS_WIND_UIGF where present).

• "native": TOTALDEMAND plus estimated rooftop PV generation. Closest to end-use consumption. If the rooftop PV component is not available in DISPATCHREGIONSUM the function warns and returns TOTALDEMAND; users should join with aemo_rooftop_pv() for a full native-demand estimate.

Timestamps are AEST (UTC+10, no DST).

Value

An aemo_tbl with columns settlementdate, regionid, demand_mw (the requested measure), plus the underlying DISPATCHREGIONSUM columns used in the derivation.
