aemo (version 0.4.3)

aemo_settlement: Settlement cash-flow and residue tables

Description

Returns settlement reconciliation tables from MMSDM. Three views are exposed, corresponding to the three tables gentailer hedging workflows most commonly need:

Usage

aemo_settlement(table = c("cashflow", "fcas_recovery", "residues"), start, end)

Value

An aemo_tbl with the raw MMSDM columns for the requested table.

Arguments

table

One of "cashflow", "fcas_recovery", or "residues".

start, end

Window (inclusive) applied to SETTLEMENTDATE / PAYMENTDATE.

Details

• "cashflow" (default): SETCFM (NEMDE-derived energy settlement amounts per participant per trading interval).

• "fcas_recovery": SETFCASREGIONRECOVERY (the recovery allocation of FCAS costs to customer load per region per trading interval).

• "residues": SETRESIDUECONTRACTPAYMENT (settlement residue auction (SRA) contract payments against interconnector settlement residues).

Access. These tables are in the MMSDM monthly archive (not the NEMweb Current retention). Expect two-month latency between trading date and availability.

See Also

aemo_mlf() for the transmission loss factors that scale settlement amounts; aemo_interconnector() for the flow side of the residue calculation.
