Electricity Billing?

Below is a quote from an electricity supplier:

"If you use an one-tarrif-type, you can have prices for kWh from $0.15-$0.19 per kwh.
If you have a two-tarrif-type your prices for high tarrif can be from $0.21 /kWh to $0.16 /kWh with all taxes for low tarrif can be from $0.13 /kWh to $0.11 /kWh with all taxes."

Does anyone here understand this statement? I am a typical domestic user. Which tarrif applies for me? And how am I gonna be charged?

I have no idea. you need to make the supplier explain it to you. call them..wait on the line for the 30 min. plus and make them tell you. if the first one can't answer your questions...ask for a supervisor and go from there. don't settle. good luck to you.
