In support of The Crown Estate's Future of Offshore Wind report, this data describes regional areas of potential opportunity for offshore wind development & leasing in England and Wales, as identified in The Crown Estate's Whole of Seabed analysis (Whole of Seabed Methodology Report). Three key indicative regional areas of opportunity have been identified in English and Welsh waters: the North East, the South West (Celtic Sea), and more dispersed areas in Other Regions. Within the North East and Celtic Sea regions, the contiguous areas of opportunity shown have been identified as the optimal areas for potential future development. The resource in Other Regions is more dispersed and distributed across the whole of this area. There is significantly more space within all these areas of opportunity than will be needed to meet all net zero ambitions, meaning significant optionality exists.  As information and data are considered and analysed throughout the spatial design process for future offshore wind leasing, the areas identified may be subject to change. These areas will be reviewed and refined to Areas of Search and ultimately to precise Project Development Areas, through a process that will be fully informed by extensive stakeholder engagement. This data is published in the British National Grid projection.
