The Brief To provide a projection of electric vehicle maximum demand impacts by postcodes in Ausgrid’s network (225 postcodes in total) that can be used as an input to Ausgrid’s post model adjustment for the zone substation spatial demand forecast for 2020.
The Approach Evenergi, with the collaboration of Ausgrid, has built a bottom-up modelling tool (GridFleet) for predicting the impact of electric vehicles on distribution Networks. By applying the fundamental principles and algorithms of GridFleet’’s typology-based methodology, the following method was adopted to deliver this project:

  1. Project electric vehicle maximum demand impact based on data obtained for each of the 225 postcodes in the Ausgrid license area based on data obtained from key data sources such as Australian Bureau of Statistics and Ausgrid zone substation interval data.
  2. Produce hourly interval typical load profiles for summer weekday, summer weekend, winter weekday and winter weekend out to 2040
  3. Provide scenario modelling for the five scenarios identified in the Integrated System Plan
The Result The data was used by Ausgrid in its submission to the Australian Energy Market Operator for billions of dollars of annual investment  and will help drive better investment decisions around network planning.
