Tools
Run your own numbers.
Five calculators for US facilities, run on numbers you already have: a utility bill, a transformer nameplate, a panel reading. They show what your power factor is, what it costs on your bill, what correction would free up, and which unit it would take. Every result is an estimate from the formulas shown. A survey and six months on your own meter replace it with a measurement.
What these tools don’t do
Estimates, not measurements.
They don’t claim energy savings, they don’t price harmonics, heat or equipment life, and they don’t know your rate schedule. They work the formulas on what you enter. When the numbers look worth a closer look, the next step is a survey and temporary metering, then six months on your own meter.
