Ossian is a development stage offshore wind project approximately 84km off the east coast of Scotland.
At 858km² of seabed, Ossian is one of the largest lease areas to be offered by Crown Estate Scotland to any bidder in the ScotWind leasing round.
The lease area has average water depths of 72m, making the site suitable for the deployment of floating offshore wind turbines to deliver up to 3.6GW of new installed capacity – enough to be capable of powering up to 6 million homes annually and offsetting up to 7.5 million tonnes of carbon emissions each year.
Ossian will export to the UK grid via connections to Lincolnshire which are being delivered as part of National Grid ESO’s Holistic Network Design. You can learn more in National Grid ESO’s ‘Beyond 2030’ report.
About Ossian
Ossian (pronounced ‘os-si-un’) from The Poems of Ossian is the name for our proposed offshore wind farm located in waters off the east coast of Scotland.
Ossian is fitting, given the combination of scale, power, tradition, and global reach it represents. Ossian will be a critical project and will provide a significant proportion of the renewable energy capacity we need to meet government ambition and help us reach net zero.
As one of the largest wind farm developments in Scottish waters, Ossian represents a new tradition in power generation – and, like the poems, links far-off lands through our partnership of companies from around the world, bringing together local knowledge and global expertise.
