In support of its Development Consent Order application in February 2024, Mona Offshore Wind Limited set out a fixed transmission design for the Mona grid connection, confirming an offshore cable corridor of approximately 90 km from the Mona Array Area to landfall at Llanddulas in North Wales and an onshore export cable corridor of about 15 km running inland to a new Mona onshore HVAC substation south of National Grid’s Bodelwyddan substation. The design specifies up to four offshore export cable circuits at up to 275 kV, each including fibre-optic communications, buried where possible, with transition joint bays at landfall and buried onshore export cables linking the transition bays to the new onshore substation and then by 400 kV cables into the existing Bodelwyddan National Grid substation.
