Operating Cost Calculations

Similar to the Capital cost tab, the tab designated as Operating costs will display a spreadsheet showing the pump stations, HP, electric energy cost in cents/KWH, etc for calculating the annual operating costs for the pump stations.

For the current pipeline system, the calculated horsepower for each pump station is shown. For each pump station, the demand charge in $/KW per month, the energy cost in cents/KWh, the number of hours per day and the number of days per year that each pump station operates are also shown.

Based on this information, the energy cost is calculated and displayed.

Make changes as necessary and click the Calculate button to obtain the total annual operating cost.  Please note that the operating costs are strictly based on the HP required at each pump station, for electric motor driven pumps and does not include allowance for electric motor efficiency.  For a motor efficiency of 98% divide the HP required column by 0.98 and recalculate cost.
