CVR Publication and CMVRN Submission Deadline

This page provides full details of the proposed change, relevant dates and decisions.

What is the issue?

Rule 10.5.1 requires the CM Settlement Body (CMSB) to publish the Capacity Volume Register (CVR) at 5pm on the 10th Working Day (WD) after the end of a month where a CM Stress Event occurred. This also needs to be re-published every day from WD11-WD19. The intent of Rule 10.5.1 is to allow CM Volume Registration Notifications (CMVRN) submissions to continue up to 5pm. However, to generate and publish the CVR at 5pm, CMSB require 30 minutes for internal processes before publishing the CVR.

Rule 10.2.4 makes it clear that all submissions up to 5pm are valid for that WD. This could result in the CVR not accounting for CMVRN submissions after 4:30pm on the 10th WD, but as these system trades have been accepted, this results in the CVR being out of date as soon as its published.

What is the proposed solution?

This proposal seeks to amend Rule 10.5.1 to allow an extension of 30 minutes to the CVR publication time, proposing a new time of 5:30pm, to account for the additional time required by CMSB for calculating and processing the CVR prior to publishing.
