### Lot Information

Lot 1

The Welsh Government have a requirement for a supplier or suppliers to design, construct, finance and operate a new 280MW high voltage power connection at the Bro Tathan site. It is anticipated that the power will be available on a phased basis. Phase 1 - 80MW. Phase 2 - 280MW. Phase 1 power will be provided from the existing 132kV NGET Substation located on the former Aberthaw Power Station site from 2no existing bays. 2no 132kV circuits to provide power to site. There are efficiencies to be realised in carrying out Phase 2 works in Phase 1. Phase 2 power requires the NGET 132kV and 275kV substations to be rebuilt offline and diversions will be required to be carried out to connect the existing assets to the new substations. The Welsh Government Phase 1 cables will need to be diverted into a new NGET substation. From the NGET substation, 3no 132kV circuits will provide power to the Bro Tathan site. These cables will terminate into a Bro Tathan substation located at the site. At this stage, it is anticipated that this substation will consist of: 3no incoming 132kV bays; 2no bus-sec on 132kV bays; 4no 132kV feeder bays to large demand users on the site; One or two 132kV bays for 132/11kV transformers and/or 132/33kV transformers; And the ability for generation to connect in the future (via either a 132kV or 11kV bay). The grid connection will be from National Grid Electricity Transmission Network at Aberthaw. Welsh Ministers accepted a connection in April 2022 and anticipate receiving a revised offer from the ESO as a result of an 'agreement to vary' generated by National Grid as a result of required changes to the Electricity Transmission network. Welsh Government are seeking early market engagement from potential suppliers to provide an update on project timescales and inform the procurement strategies and delivery strategy for this project. Welsh Government are seeking engagement from Independent Connection Providers (ICPs). A subsequent procurement event or procurement events are anticipated to be launched in Q3 2024.
