CMP427: update to the transmission connection application process for onshore applicants
Summary
Ofgem has approved CMP427, introducing a landowner Letter of Authority requirement for new onshore transmission connection applications under the Connection and Use of System Code (CUSC). The change takes effect from 28 March 2024. This adds a documentation requirement to the application process rather than changing substantive connection terms or costs.
Why it matters
This creates an additional hurdle for developers without landowner agreements, potentially filtering out speculative applications. As such, it may reduce queue volumes but shifts costs to developers who must secure landowner consent earlier in the process, before knowing if grid connection is viable.
Key facts
- •Effective date: 28 March 2024
- •Applies to new onshore transmission connection applications only
- •Modifies CUSC application requirements
