Housekeeping Modifications
The Grid Code needs to be adaptable and responsive - it is a living document that is constantly evolving, and so requires consistent maintenance in the form of housekeeping modifications.
A Grid Code Housekeeping Modification is a modification that:
- Does not add or remove a requirement from any user of the Grid Code;
- Does not make a material change or impact to the existing compliance of any user under the Grid Code;
- Aims to ensure that the Grid Code is as accessible as possible, and that the form of each clause is well-structured and conveys the correct meaning.
Housekeeping of the Grid Code is an ongoing process, EirGrid, as TSO, is undergoing a streamlined process for housekeeping modifications from October to December 2024.
The documents below track the status of housekeeping modifications.
The following Grid Code modifications include any updates made in version 6 and any updates made after version 6 was issued.
