Estimating electrical expenses for the mining warehouse

Every week I would estimate the electrical usage and forecast my expenses for the month. I would measure each rigs electrical consumption and time in operation. I would then determine how many watts were in use and calculate total kilowatts the machines would use for the month.

Below is a sample of GPU miner calculations

I would estimate total Kilowatt hours for a 30 day period. My calculations would include all electrical components in the warehouse (miners + fans + lights + etc.).

Then I would apply the total Kilowatt hours to the electric companies sliding scale to determine how much my electric bill would be for the month.

Below is a sample of the sliding scale from the electric company

Total KW Per MonthElectrical CostsScale
                                   3,000.0 $                            0.1159981-3000 kw
                                   6,000.0 $                            0.0711133001-9000 kw

Finally based on crypto currency prices, expenses and mining difficulty I would determine if it was profitable to mine. There were many occasions were I would power off all miners for the day, week, etc until profitability increased.
