Australian National Electricity Market Model
The Australian National Electricity Market (ANEM) model is the inhouse and main modelling platform of the EEMG. ANEM is currently up to version 1.10 developed specifically for the research project titled: An investigation of the impacts of increased power supply to the national grid by wind generators on the Australian electricity industry.
The ANEM model has undergone a number of enhancements in five successive research projects. Table 1 relates the ANEM model version to specific research projects, their associated publications and to the institutes and companies that have supported these research projects. Institutions include the Australian Research Council (ARC), Australian Renewable Energy Agency (ARENA), Clean Energy Council, Commonwealth Scientific and Industrial Research Organisation (CSIRO), National Climate Change Adaptation Research Facility (NCCARF) and The University of Newcastle. Companies include Australian Gas Limited (AGL), Energy Australia Hydro Tasmania, Infigen Energy, RATCH Australia Corporation (RAC) and Vestas. These companies and institutions have all contributed to the development of the ANEM model.

The strength of the in-house development of the ANEM model over other proprietary models of the National Electricity Market is the flexibility to address non-routine research questions. An additional strength over other models is ANEM's fine resolution of analysis, for instance, version 1.10 provides half-hourly resolution for dispatch and energy generated for 315 generators, congestion on 68 transmission lines and wholesale spot prices and phase angles for 50 nodes plus daily CO2 emissions by generator.
PLEXOS
The PLEXOS® Integrated Energy Model is commercial linear optimisation software developed by Energy Exemplar. Their software has datasets for several electrcity markets, including the Australian National Electrcity Market. This commerical package provides a quick, easy and low resolution way to address standard research questions. In contrast, the Australian National Electrcity Market (ANEM) Model is EEMG's inhouse model designed to address nonstandard research questions with high resolution.
The EEMG has used PLEXOS in two projects:
