What is being proposed

Following a review of Legal Text, NESO have identified minor errors and improvements to CUSC Section 14. These are either errors which were present in approved legal text, or formatting, numbering or cross-reference errors introduced as a result of multiple implementations over time.

Current status

Proposal raised on 12 November and will be presented to the CUSC Panel on 28 November 2025. The CUSC Panel agreed that further clarifications were needed on the proposed legal text. CMP464 will be discussed at the Panel meeting on 30 January 2026 where Panel will agree the Governance route and next steps. The Proposer of CMP464 will present the modification to Panel in the 27 February 2026 CUSC Panel. [09/03/2026] The Panel Panel unanimously agreed that CMP464 should follow the Fast Track - Self Governance route and proceed to be implemented.

Analysis

NESO proposes to correct minor errors and formatting issues in CUSC Section 14 through modification CMP464. The changes address legal text errors, cross-references, and numbering problems accumulated from multiple code implementations. The Panel approved fast-track self-governance route with implementation following appeal period closing 23 March 2026.

Why it matters

Administrative housekeeping that fixes technical drafting errors without changing substantive rules or market mechanisms. As such, this represents routine code maintenance rather than policy reform.
