Formal title: Updates to BSCP520 to align with working practices and UMSUG recommendations

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


CP1522 seeks to address the following issues with BSC Procedure (BSCP) 520 ‘Unmetered Supplies Registered in SMRS’:

  • The requirement for Meter Administrators to calculate reactive power is redundant;
  • The split of responsibilities for Unmetered Supplies between the LDSO and the Unmetered Supplies Operator (UMSO) is not clear; and
  • BSCP520 does not reflect the June 2019 updates to the Master Registration Agreement (MRA) Related Meters Meter Asset Provision (MAP).
