Analysis
GC0169 makes technical corrections to the Grid Code following implementation of EU Connection Codes under modification GC0136. The modification was split into two parts (GC0169 and GC0173) and processed through standard governance with a joint Grid Code/Distribution Code workgroup. Final modification report was sent to Ofgem on 7 October 2024.
Why it matters
Administrative housekeeping that tidies up drafting inconsistencies without changing substantive obligations or costs. As such, this reflects the complexity tax of maintaining dual regulatory frameworks rather than any meaningful reform.
