26. Scottish Renewables, An industry view of the Draft Sectoral Marine Plan for Offshore Wind (December 2018), recommended a 30% MW attrition rate - a higher figure for Scotland given the more challenging conditions here relative to the rest of the UK, particularly regarding water depth, ground conditions and grid charges. This attrition rate reflects reduction in eventual capacity both at a project level (where an entire project ceases to be progressed), and within project (as MW tend to be lost from initial design to construction).

27. To result in a final area of seabed under lease capable of enabling up to 10 GW of generating capacity, the initial area covered by Option Agreement arising from ScotWind Leasing needs to allow for the attrition of capacity (as per 26 above). The initial area needs to offer the flexibility designed into ScotWind Leasing, which allows for Option Agreements areas to be three times the area of the eventual project, to reduce the risk to developers that a viable project may not be identified within an Option Agreement area. Applying these factors alongside the assessment density (5 MW/km2), indicates that an initial area of seabed under option agreement of 8,571.4 km2 would be necessary to best enable operational development of up to 10 GW of generating capacity.
