List of Change Proposal Circulars
We publish Change Proposal Circulars (CPCs) when communicating BSCCo change information, and in particular when requesting Impact Assessment responses to Change Proposals and Draft Change Proposals from Industry Participants (BCAs and PACAs).
Timetable for circulars
The Change Register includes a tab for the Change Proposal Impact Assessment Timetable which provides the dates that Change Proposal Circulars will be issued. It also contains information on the submission cut-off dates of changes for the relevant Releases.
