Marginal loss factors (MLFs) are now a hot topic in the NEM after being a relatively unexciting feature of the market. Previously, in the period 2000-2015, MLFs were reasonably predictable and variations year-on-year were minor. This reflected the stability of the generation sector.
In contrast with today, new generators are connecting to very different parts of the network at an unprecedented rate. This week’s Chart of the week uses data from our Marginal Loss Factors interactive map. We analyse changes in MLFs over the past decade.
