Energy and utility operations calculators
Allocate generation expense per delivered kWh and treatment expense per delivered water volume. These are operating-cost worksheets, not plant sizing or water-treatment instructions.
Generator plant operating cost per kWh
Calculate generation operating cost from metered output and recorded fuel and maintenance expenses.
Open calculator →Water treatment operating cost
Allocate measured treatment expense over delivered water volume.
Open calculator →Electricity bill blended and variable rate
Separate an effective all-in electricity bill rate from the entered energy-charge component.
Open calculator →Fuel reserve operating runtime
Estimate constant-consumption runtime from usable fuel and a measured or supplied matching burn rate.
Open calculator →Equipment ownership cost per hour
Recover economic ownership and running cost at realistic utilization.
Open calculator →Refrigeration operating energy cost
Calculate measured refrigeration electricity cost across operating schedules.
Open calculator →Air compressor unloaded energy cost
Separate measured loaded and unloaded compressor energy and operating cost.
Open calculator →Pump electricity cost
Price measured pump electrical demand and running hours.
Open calculator →Electrical load factor
Compare average electrical demand with measured peak demand over the same billing period.
Open calculator →Generator fuel operating cost
Budget measured generator fuel burn and running hours.
Open calculator →Water saving fixture payback
Price supplied flow reduction and observed usage without selecting fixtures.
Open calculator →Power factor bill penalty payback
Evaluate correction solely from entered utility billing penalty scenarios.
Open calculator →General total cost of ownership
Add acquisition, recurring, one-off and end-of-life costs over a supplied ownership period for an asset or service.
Open calculator →Battery backup energy runtime
Estimate constant-load backup duration from supplied battery energy and real-watt loads.
Open calculator →Solar quote cost per watt and specific yield
Compare supplied solar quote cost and annual AC energy against declared DC nameplate capacity.
