BSC Changes impacting Unmetered Supplies Operators
This page shows which Modifications and Change Proposals have been identified as impacting Unmetered Supplies Operators. Please note that the assessment of where impacts may affect certain roles within the electricity market may be amended during the course of the Change process.
P456 ‘Enable Elexon to procure ancillary Technology Services for use by BSC Agents’

P463 ‘Introduce a Standard Change’
To introduce a new change process – a ‘Standard Change’ process – into the BSC arrangements that would allow for certain, low risk, predictable and repeatable pre-authorised changes to be implemented without following the existing Change Proposal or Modification procedures.
