Provision of indicative marginal loss factors

Interested parties may on occasion require marginal loss factors (MLFs) under conditions that differ from the Forward Looking Loss Factor (FLLF) methodology. Examples include:

• A proponent may wish to assess the potential impact on published MLFs if a generating unit is installed or upgraded at a particular connection point.
• A market customer may wish to assess the impact on the published MLF at a connection point without the contribution of a nearby generating unit.
• A market participant may wish to assess the MLF of an embedded generator for which AEMO does not normally calculate and publish an MLF.

To assist interested parties with such requests, AEMO currently provides a service to calculate indicative MLFs under non-standard assumptions for a nominal fee.The following document provides details of the indicative MLF calculation process, including fees and data requirements.
