VEKTA GROUP ENERGY DIVISION produced the technical note "Onshore Substation Layout Philosophy" (document ref LLYR-FLOV-VGED-TEC-002, revision 0) for the Llŷr projects’ new purpose-built onshore substation in Pembrokeshire. The note set out the high-level principles and preliminary planning-envelope layout for the Llyr Wind Farm Onshore Substation that would connect the two floating wind farm circuits to National Grid’s Pembroke 400/132kV Substation via a proposed 400kV circuit, including allowances for AIS/GIS options, transformers and associated compounds.
