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.

Highlights

August 2021 had the highest daily average number of notified contracts. The 12 month rolling average of daily average notified contracts has been increasing more steeply since January 2021.
