Grid Connection



In comparison to other UK coastal sites, existing land based grid connections are excellent in Pembrokeshire with a 400 kV National Grid connection being available at the Pembroke Power Station site. The region is also close to large population centres along the M4 corridor with high electricity demand. As part of an evidence based approach by the Welsh Government, Halcrow Consultants completed a feasibility study on the infrastructure required for Marine Renewables off the Welsh Coast.


North Wales already has an established energy generating network through the Wylfa Nuclear Power Station, Dinorwig and Maentwrog hydroelectric power stations and several offshore wind farms. A 400 kV double circuit overhead line runs between Wylfa and Pentir and this could be utilised by the emerging marine energy companies. The current national grid connections offer a suitable gateway to connect the energy production to the rest of Wales and the national grid. However the establishment of a new nuclear power station at Wylfa of 2.8 gigawatts (GW), could produce more energy than the existing power station, which could exceed the amount of electricity that the existing network could handle. The North Wales Connection is a proposed second connection for the Wylfa Newydd nuclear power station on Anglesey.
