Issue 112 ‘Clarifying Half Hourly Data Collector (HHDC) obligations within BSCP502 regarding the fault investigation process.’

At the May 2023 Performance Assurance Board (PAB) meeting, Elexon presented the findings report for an Assurance Information Request (AIR) on SVA Risk 005 (Fault Resolution). The PAB responded with questions around some of these findings, specifically around: The reporting of alarm flags through Hand Held Reads (HHR); Differing approaches to dealing with several types of alarm flags and which alarm flags the Half-Hourly Data Collectors (HHDCs) choose to report on; and General concerns around HHDC non-compliance with the BSC.

Elexon reviewed the findings report for an Assurance Information Request on SVA Risk 005. The Performance Assurance Board (PAB) responded with questions around HHDC obligations and general concerns around HHDC non-compliance. Elexon further reviewed party responses and concluded that three of the five concluded findings were compliant with the BSCP502 but are not adequate for purpose and required an additional review. 

Elexon considers that leaving this issue unresolved could lead to impacts on Settlement, this could lead to a further occurrence of this issue happening and a high materiality impact if left unresolved.
