AQ (Annual Quantity)

Annual Quantity is the estimated yearly gas consumption for a meter point, used for billing, supplier switching, and determining site classification.

What is AQ?

Annual Quantity (AQ) is the estimated annual gas consumption for a supply point, measured in kilowatt-hours (kWh). It's used throughout the gas industry for planning, billing, and regulatory purposes.

How AQ is Calculated

AQ is calculated based on:

  • Historical meter readings
  • Weather correction factors
  • Property characteristics
  • Industry standard algorithms

AQ and Site Classification

AQ determines whether a site is classified as:

ClassificationAQ ThresholdBilling
SSP (Small Supply Point)Under 73,200 kWhEstimated + reconciliation
LSP (Large Supply Point)73,200 kWh and aboveDaily metered

Why AQ Matters

AQ affects:

  • Transportation charges - higher AQ means higher capacity charges
  • Supplier switching - AQ transfers with the supply point
  • Contract pricing - suppliers use AQ for quotes
  • MAM activities - meter sizing and replacement decisions

AQ Updates

AQ can be updated when:

  • Sufficient meter reading history exists
  • Property usage patterns change
  • Customer requests a review
  • Industry reconciliation processes run
