CAP151 was raised by National Grid in June 2007 and sought to introduce a publicly available register (the “Transmission Works Register”), established and maintained by National Grid. 

The Transmission Works Register contains information about Transmission Reinforcement Works set out in Generators’ or Interconnector Owners’ Construction Agreements, or the relevant Distribution Network Operator’s (DNO) Construction Agreements in respect of transmission works required for distributed generators with a Bilateral Embedded Licence exemptable Large power station Agreement (BELLA), until such works are completed. 

The Transmission Works Register is similar to the current Transmission Entry Capacity (TEC) register and embedded generator MW register and sets out, for each Construction Agreement and BELLA, information on the project, the completion date and the associated Transmission Reinforcement Works.

National Grid considers that the Transmission Works Register provides a more comprehensive and timely picture of the transmission works required to connect a given generation project.  By mapping planned transmission works against signed construction agreements, National Grid considers that the Transmission Works Register enables users to identify potential gaps appearing as a consequence of another user reducing their capacity or terminating their construction agreement.

Below are two downloadable Excel spreadsheets and accompanying Word versions of these files; ‘Transmission Works by Generator’ and ‘Generator by Transmission Works’ a database in Access 2003 format is also available by email. 

If you have any queries regarding the Transmission Works Register please contact Jeremy Tennant -(jeremy.tennant@uk.ngrid.com).
