4 What each plan costs
Estimated annual cost by plan
Your usage scaled to a full year. Green is the cheapest.
Daily usage vs cost
Your average day: bars show how much you spend each half-hour on the selected plan (left axis), the line shows how much energy you use (right axis). Tall bars over cheap-energy times are where a plan stings.
What each bill is made of
Annual cost split into general usage, controlled load and supply charge, less any solar credit.
Estimated cost by month
Each plan across the months covered by your file.
Estimates only. Real bills vary with rounding, seasonal usage, GST, connection fees, membership discounts, demand charges and solar export. Always check the plan's full terms.
5 Shifting your usage
Time-of-use plans reward you for using power when it's cheap. This looks at how much of your usage lands in expensive peak/shoulder periods, and estimates what you'd save by moving some of that to off-peak — for example running the dishwasher, washing machine, dryer, pool pump or EV charger overnight.
