When a read is rejected by CMOS due to validation reasons, but the data submitted is accurate then the retailer/wholesaler can submit a re-read.
Re-reads are important for calculating accurate bills based on volumetric consumption.
Obligations under the codes
The relevant wholesaler or retailer who submitted the original read must investigate the read and if found to be correct, they may re-submit and indicate it is a re-read. More details on re-reads can be found in CSD 0202 (Meter read submission: process).
