How to calculate the electricity fee?
Example: S17 electricity fee 1TH/day=$0.075kWH*46W/TH/1000*24H= $0.0828/TH/day, power consumption is 1.104 kWH/TH/day.
So when you buy, the KWH will automatically round up to 2 KWH, so essentially you are buying 2kWH*$0.075kWH=$0.15. The remaining power of 0.896 kWH will still remain in your account for the next deduction.
Note that everytime you purchase power, you will be required to purchase a minimum value of USD 50 worth of power, with the power amount rounding up to the next whole number.
