TEC Register

The data file contains the latest version of the TEC Register including all changes up to publication. This file will be updated twice weekly on Tuesdays and Fridays.

Please note:

Project Nos: We plan to phase out the use of Project IDs in favour of Project Nos which are now found included in the Dataset - we will continue to include Project IDs until the end of this year. If there is more than one Stage the Project No will be followed by a dash and the relevant stage number.

Project IDs: are Case Sensitive i.e. a0l4L0000005iPb; a0l4L0000005ipb and a0l4L0000005ipB relate to different projects.

Staging: If a project includes staged TEC there will be an associated number in the Stage column. Some projects have two separate lines without numbers - this usually indicates that the project is already built and the Customer is perhaps adding a different type of generation or building new generation to be connected at a future date. Once built the second line will fall away and the TEC incorporated into the overall project.

Stage

Title Stage
Type number
Description Stage refers to Staged TEC – how much TEC the Customer will connect and when.
Comment The customer may choose to bring on capacity in chunks to align with their build /commissioning program. Staged contracts are also used when a customer may only be able to bring on a proportion of their total capacity at a particular point in time ahead of further reinforcement works being carried out, completion of which would allow the remaining TEC onto the system. Field is only completed if the project is staged otherwise it will be empty

Project Status

Title Project Status
Type string
Description Indicates what stage the Project is at in it's build cycle
Comment The Status classifications are very much based on information we have either ascertained from the customer or from another source, i.e. government website. It’s important to note that we hold no authority on the Status classifications on Registers and are produced on an “as far as we are aware” basis. To this end we deem the classifications to mean: Scoping – we are not aware that a planning application has been made Awaiting Consents – we are aware (or the customer has told us) a planning application has been made Consents Approved – we are aware (or the customer has told us) the planning application has been approved
Example Scoping
