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.
