This data reflects outputs from a suite of electricity system models which represent different parts of the electricity supply and end-use value chain. The models were run to deliver least cost projections of electricity sector outcomes for the roadmap and counterfactual scenarios of the Electricity Network Transformation Roadmap, developed through a collaboration between CSIRO and Energy Networks Australia (ENA). For further details of the Roadmap process, see the Related Resources listing on this page.

The data is predominantly annual projections at the national level to the year 2050. However, there are two figures which present half hourly data for South Australia in 2036. Also there are seven figures which provide five yearly projections at the state level.

The data includes projections of:

• the electricity generation mix, including renewable energy share;
• greenhouse gas abatement;
• household retail electricity bill differences;
• cumulative electricity system expenditure;
• share of electric vehicles and the associated impact on energy consumption and peak demand;
• electricity and gas substitution;
• battery storage profiles and capacity requirements;
• wind capacity factors during peak times; and
• rooftop solar capacity.

Note that the projections were made over the period 2015 to 2016 and therefore will not include any unexpected changes in the electricity sector since that time.
