Submitted Notifications and percentage of Rejections

This graph shows daily average ECVN submissions and rejections for the period of one year. It compares the data to last year’s average. The 2% rejection threshold is an internal performance measure. If the number of rejections goes above the threshold, Elexon will provide additional commentary into the cause.
