Distribution Loss Factors (DLF) by connection point

Source: R/loss_factors.R
aemo_dlf.Rd

Returns the Distribution Loss Factor for NEM connection points from the MMSDM LOSSFACTORMODEL table. DLFs measure the average energy loss on the distribution network between a connection point and the transmission network boundary; a DLF of 1.02 means the generator must produce 2% more energy than it delivers to the transmission system.

Usage

aemo_dlf(year = NULL, connection_point_id = NULL)

Arguments

year

Financial year(s) as "YYYY-YY". NULL returns all available years.

connection_point_id

Optional character vector of connection point IDs.

Value

An aemo_tbl with at minimum financial_year, connectionpointid, and dlf.

Details

DLFs are published annually by AEMO (NER 3.6.3) and combined with MLFs in settlement to give the total loss factor (TLF = MLF x DLF) used in energy payments.
