Pump Efficiency Calculation Tool (MS Excel Spreadsheet)

Introduction to spreadsheet

This tool calculates the energy efficiency and energy performance of water (and waste-water) pumping facilities. The following Help section explains some of the Inputs, Calculations and Outputs in this tool.

This tool is based on a tool originally developed by Tipperary Energy Agency, Midlands Energy Agency & Kerry County Council.

Main Inputs

  • Electrical energy consumption (measured or nameplate)
  • Run hours
  • Static head (from drawings)
  • Discharges pressure (from pressure gauge)
  • Flow rate (from flow meter or estimate)
  • Average unit price (electricity)

Main Outputs

  • Motor, Pumping (Hydraulic) and System energy efficiencies
  • Motor, Pumping & Piping Losses
  • Total Energy Consumption & Energy Cost
  • CO2 Emissions
  • Energy Performance Indicators
  • Comparison of Actual Performance v/s Best Practice Performance Certificate
