Vince from Hartford. Found the demand meter on a plastics manufacturer recording in kW but the tariff bills demand in kVA. The conversion factor based on actual power factor meant the client was being billed more than they should have been. Took me a while to unravel. Anyone else found this unit error?
Demand meter recording kW instead of kVA — four-year error
Walt from Pittsburgh. Yes and it is a real trap. Some older meter installations have the recording unit hardwired in a way that does not automatically match what the tariff specifies.
Derek from Charlotte. Always verify what unit the meter physically records and trace how it flows through the billing calculation. Do not assume the meter unit matches the tariff unit.
My client had been overbilled for four years. The utility acknowledged the unit mismatch immediately when I showed them the meter configuration documentation.
Terry. What was the total recovery?
Just over $29,000 after the utility processed the correction. Took 90 days but once they confirmed the unit error there was no dispute about the amount.
