Framework
BREE modelled the Australian electricity sector to 2050 using the E4cast model, which is a dynamic partial equilibrium model of the Australian energy sector. The E4cast framework provides a detailed treatment of the sector, focusing on domestic energy use and supply.
Demand
BREE used internal demand forecasts for Western Australia and the Northern Territory, as well as the demand forecasts published by the Australian Energy Market Operator in the 2012 National electricity forecasting report, for each of the regions in the National Electricity Market electricity demand forecasts. The scenarios included:
- high demand or 'fast world recovery', equivalent to a high economic growth scenario
- medium demand or 'planning', equivalent to medium economic growth
- low demand or 'slow growth', equivalent to low economic growth.
Further information on Australian Energy Market Operator's demand forecasts is available in the 2012 National electricity forecasting report.
Technology costs
The BREE modelling used the Australian energy technology assessment 2012 for electricity technology costs.
Fuel costs
The BREE modelling used the 2012 ACIL Tasman fuel price projections, which are also summarised in the 2012 Australian Energy Technology Assessment.
