This is the summary skip rate and skipped volume data for each 30min period for each stage of exclusion described in the LCP methodology. 

19/12/2024: in the data published today, we have corrected the handling of an edge case and updated the previous days’ data to reflect this change.

Skip Rate - Summary

"Post System Action Skip Rate" – A more targeted measure of avoidable skips not in context of all actions taken at the time. The occurrence of these skips is far less the BM Skips.

Skip Rate - In Merit Post System Action

"All Balancing Mechanism Skip Rate" (BM skip) – A measure of avoidable skips, taking into consideration all balancing mechanism actions we could have taken over the relevant period.
