Adjustments to invoice Clause Samples

Adjustments to invoice. (a) If, after calibration, Measuring Equipment is found to be in error: (i) in excess of the tolerances set out in the Measurement Manual; and (ii) the total measurement error for a Receipt Point or Delivery Point is more than 1% of the total quantity of Natural Gas measured at that point since the last calibration, in the absence of a clearly identifiable event that has caused the calibration error, as determined by the Service Providers acting reasonably and in good faith, the Service Providers must issue a correction to any invoices issued to the Shipper since the last calibration. (b) The correction will be equivalent to half the determined error applied to all quantities measured on the Shipper's account at the Receipt Point or Delivery Point, as the case may be, over the period since the Measuring Equipment was last calibrated.
