Power utilities generally bill commercial customers based on their peak usage levels, called peak demand (in kW) and energy consumption (in kWh). Peak (or maximum) demand is the highest demand level recorded over the billing period. You can view peak demand values on your meter’s display.
Your meter calculates the average current demand and kW, kVAR and kVA demand using sliding window demand methods. It supports coincident demand values when a peak demand is detected.
Your meter’s default configuration is suitable for most applications, or you can customize it for your specific application. You can configure the minimum time between consecutive demand resets.
Peak demand reset lockout
The demand reset lockout time sets the minimum time allowed between consecutive demand resets; the meter ignores any attempts to reset demand that occur within the lockout period.
The peak demand reset lockout period is user-configurable (typical default value is 25 days).

See the ION Setup online help for instructions on how to configure demand peak and the demand reset lockout period on your meter.
