CMP470: Introducing an Oversubscribed Technologies Commitment Fee | National Energy System Operator
Summary
CMP470 proposes introducing a commitment fee floor for all technologies that are oversubscribed relative to Clean Power 2030 capacity targets. The modification targets generation developers with high impact and transmission owners with medium impact. It is proceeding through urgent governance route to workgroup stage.
Why it matters
This creates a financial barrier that could reduce queue speculation by forcing developers to pay upfront for oversubscribed technologies, effectively pricing connection rights rather than queueing them. The urgency suggests this addresses immediate problems with queue management ahead of 2030 targets.

Memo
What this is about
NESO has raised CMP470 to introduce commitment fees for all generation technologies that are oversubscribed relative to Clean Power 2030 capacity targets. The modification creates a financial floor through an "Oversubscribed Technologies Commitment Fee" that developers must pay upfront to secure connection rights for technologies where queue applications exceed what the system actually needs.
This addresses the endemic problem of speculative queue applications that clog the connections process. By making developers pay for oversubscribed technology slots rather than simply queuing for free, CMP470 aims to filter out uncommitted projects and accelerate genuine development. The urgent governance route signals NESO views this as critical for hitting 2030 decarbonisation targets – queue reform cannot wait for normal modification timescales.
Options on the table
The source material does not present distinct options for comparison. CMP470 proposes a single approach: introducing commitment fees for all technologies that exceed Clean Power 2030 capacity requirements. The modification will proceed to workgroup stage where detailed design options will likely emerge around fee levels, oversubscription thresholds, and payment mechanisms.
Questions being asked
No specific consultation questions are available in the source material. The modification has only reached proposal stage and will proceed to workgroup consultation where detailed questions will be developed.
How to respond
The modification is currently at proposal stage proceeding through urgent governance to workgroup. Future consultation opportunities will be available once the workgroup develops detailed proposals.

Formal consultation documents and response mechanisms will be published as the modification progresses through workgroup and code administrator consultation stages.
