2. Grid Code Standard Modification Key Points
A Grid Code Modification Proposal that does not fall within the scope of a Significant Code Review subject to any direction by the Authority, nor meets the Self-Governance Criteria subject to any direction by the Authority.
The Panel in conjunction with the Code Administrator will determine the timeline, number of Consultations required and agree terms of reference.
At the Workgroup stage parties can raise an alternative modification proposal which has the support of the majority of Workgroup members or the Workgroup Chairperson as better meeting the Grid Code objectives.
The Workgroup vote is an informal recommendation for the Panel and will be an element incorporated within the Report submitted to the Panel.
If an alternative is suggested, it has to be better than the baseline or better than the proposed solution.
