Change Proposals

A proposal to amend Rule 3.3.5 for greater clarity, to ensure that those with the ability to bid in the CM auctions are acting independently so that the market remains competitive.

This amendment would allow Capacity Market Unit (CMU) to be merged after Prequalification, facilitating greater commercial flexibility and efficiency and helping to manage Capacity Market costs.

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.
