CMP465: Construction Progression Milestones (M5-M8) Neutrality | National Energy System Operator
Summary
CMP465 proposes to allow affected generators to reset their construction progression milestones (M5-M8) back to what they would have been without the G2tWQ (Gate 2 to the West Queue) extension granted until 2026. The modification follows NESO's decision to extend G2tWQ connection offers beyond their original 2025 deadline. It proceeds under urgent modification procedures with Authority decision pending.
Why it matters
This creates a limited remedy for generators disadvantaged by queue management decisions, allowing them to recover lost milestone positions but only for specific construction stages. The modification addresses administrative queue changes rather than fundamental connection reform, as such it maintains the queue-based allocation system while trying to preserve pre-disruption positions.
Key facts
- •G2tWQ connection offers extended from end-2025 to 2026
- •Only affects construction milestones M5-M8, not earlier stages
- •Classified as urgent modification requiring Authority decision
- •Low impact designation for affected parties
