had a smart meter installed 4 days ago to utilise the solar panels 1.1kwh, selected the time of use option and find here in wa it is net feed and peak is 40c/unit whereas the flat rate is 20c/unit, off peak is about the flat rate and shoulder in between, i cant find the info on the site but have requested a info pack as it changes at the end of sept fot the summer rates and i suspect it will lengthen the peak hours due to aircon use,so far i am way down on usage as during the day i use little,and get 47c/unit to the grid, they own the meters so i think they will change them all here sooner or later
