COD anchored to NESO Connections Register entry PRO-003461 for Celtic MPI. The register records this project (developer: National Grid Interconnector Holdings Limited; connection site: Alverdiscott 400 kV substation, Devon; 1,500 MW import / 1,500 MW export) with an effective TEC date of 31 October 2037. The effective TEC date is the date from which the project becomes entitled to its grid connection capacity, i.e. when it expects to be operational. Status: Scoping (Gate 1) as of the register entry. Project remains at early scoping stage; the 2037 date is the developer's stated target, not a build-locked commitment. Treat as a published projection.
