>**Please note:**<br/>  
**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.<br/>  
**Project IDs:** are Case Sensitive i.e. a0l4L0000005iPb; a0l4L0000005ipb and a0l4L0000005ipB relate to different projects.<br/>  
**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.
