FCAS enablement volumes by generator unit

Description

Returns the MW enabled for each of the ten Frequency Control Ancillary Services (FCAS) per DUID per 5-minute dispatch interval from DISPATCHLOAD. This is the quantity side of the FCAS market: how much each unit was enabled (dispatched) to provide each service, as distinct from the price returned by aemo_fcas().

Usage

aemo_fcas_enablement(
  duid = NULL,
  start,
  end,
  service = NULL,
  intervention = FALSE
)

Arguments

duid	Optional character vector of DUIDs. NULL returns all units. See aemo_units() for the full DUID registry.
start, end	Window (inclusive), character or POSIXct.
service	Optional character vector of service names, e.g. c("raise6sec", "lowerreg"). Case-insensitive. NULL returns all ten services.
intervention	Logical. Default FALSE.

Details

Ten services are active since 9 October 2023 when Very Fast (RAISE1SEC / LOWER1SEC) commenced. Before that date only eight services are present; the raise1secmw / lower1secmw columns will be NA for intervals before that date.

Value

An aemo_tbl with columns settlementdate, duid, and one column per FCAS service (raise1secmw, lower1secmw, raise6secmw, lower6secmw, raise60secmw, lower60secmw, raise5minmw, lower5minmw, raiseregmw, lowerregmw). Values are MW; zero means the unit was not enabled for that service.
