CP1565 ‘Updates to address Central Management System issues’
Formal title: Updating BSCP520 to address operational issues in the Central Management System
This CP seeks to update BSCP520 to contain clearly outlined processes for approval and fault reporting of Central Management Systems.
The BSC does not currently contain clear guidance on how Central Management System (CMS) and Measurement Central Management System (mCMS) applications are approved. Additionally, when faults are detected, the BSC does not provide guidance on how they are reported. As a result, common operational issues have been identified with CMS that pose a risk to Settlement in terms of Half Hourly (HH) energy calculation accuracy.
Central Management Systems (CMS) are used in dynamic street lighting control to manage the electrical load of Unmetered Supplies (UMS) equipment that can operate at multiple on/off time and/or dimming levels. The electrical loads are recorded as events, which are used by a Meter Administrator (MA) to calculate consumption data for Settlement. BSCP520 ‘Unmetered Supplies Registered in SMRS’ details the requirements for Unmetered Supplies (UMS) in the Supplier Meter Registration Service (SMRS).
