The latest stage in the ScotWind Leasing process has been reached. The 17 initial projects – out of a total of 20 – have submitted updates to their Supply Chain Development Statements (SCDSs).

The SCDSs outline critical early-stage project information that can then be used to coordinate, support, and grow the supply chain in Scotland.

SCDSs are designed to provide a structure for project specific supply chain information to be communicated with government and industry, through the initial stages of project development, to deployment and into operations.

These updates record a slight change to the figure for anticipated average investment in Scotland. The previous figure of £1.4bn per project has been revised to £1.5bn per project.

The next set of SCDS updates are due in 2026.

The remaining three ScotWind projects, which came through the Clearing process, are due to submit their first SCDS updates later this year.

There are currently seven offshore windfarms operating in Scottish waters, with a total generating capacity of 1.9 GW.

Based on the Scottish Government’s Renewable Electricity Output Calculator, 1GW of capacity is enough to power more than 560,000 homes.

The interactive map below shows operating windfarms and those that are currently under construction or in development. Some are part of ScotWind and others were part of earlier leasing processes. Details of windfarms, including supply chain commitments for ScotWind projects, can be accessed by clicking them on the map.

The projects in development aim to start generating electricity by or before 2032.
