Generator bid stack

Returns BIDDAYOFFER_D (daily bid summary: 10 price bands, MaxAvail, fixed load, locked at 12:30 D-1), BIDPEROFFER_D (per-interval availability and rebids), or the two joined on (duid, settlementdate, bidtype).

Usage

aemo_bids(
  duid,
  start,
  end,
  resolution = c("day", "period", "joined"),
  allow_large = FALSE
)

Arguments

duid

Character vector of DUIDs. Required.

start, end

Window.

resolution

One of "day" (default, BIDDAYOFFER_D only), "period" (BIDPEROFFER_D only), or "joined" (BIDDAYOFFER_D inner-joined to BIDPEROFFER_D on (duid, settlementdate, bidtype)).

allow_large

Logical. Default FALSE.

Value

An aemo_tbl.

Details

Parent / child structure. BIDDAYOFFER_D carries the price bands (priceband1..priceband10), which are locked at 12:30 on the day ahead and cannot be rebid. BIDPEROFFER_D carries the per-interval availability bands (bandavail1..bandavail10), which can be rebid intraday. Serious bidding analysis (Goncalves & Menezes 2022 Energy Economics 113 106398; Nelson et al. 2024 AJARE 68(4)) needs both joined.

Size warning. BIDPEROFFER_D monthly archives are multi-gigabyte. By default aemo_bids() refuses spans longer than 30 days; pass allow_large = TRUE to override.

Upstream gap. AEMO has a documented gap in BIDPEROFFER_D between March 2021 and July 2024. Rows in that range may be missing.
