Transmission Access – Connect and Manage

Modification status: Concluded

Last updated: 25 September 2018

It is proposed that Generators who wish to connect to the system should have a fixed date for receiving TEC. This date, the ‘TEC effective date’, will be the later of the completion of “local” transmission works or an agreed fixed lead time. The fixed lead time will be discussed and agreed in the amendment assessment stage and codified in the CUSC. Initial options are 3 years (aligns with planning restrictions in Scotland); or 4 years (more consistent with historic performance of providing reinforcements).
