Finally I saw tiny tiny written: "E", which means the bill is estimated.
How they managed to work out that figure? Guessing! When you have a net-metering system and produce your electricity from PV modules on your roof or garden, it depends very much on the time of the year, temperature, sunshine hours, dust levels, humidity.... how much you produce and the time you have heavy loads (cooking, washing, air-con, pool pump etc) which deduct the kWh you deliver to the grid.
So, if you can detect 2 tiny "E" on your EAC bill you will have another surprise when you receive your next bill, and there is no estimation....
