Spiorad na Mara is a Scottish Gaelic expression meaning Spirit of the Sea.

The proposed wind farm is set in an area approximately 5-13 kilometres off the west coast of the Isle of Lewis. With a potential expected capacity of around 900MW, it could meet the average annual electricity needs of around 815,000 Scottish homes and save more than 1.36 million tonnes of harmful CO2 emissions every year.

The project is owned by Northland (75.5%) and ESB (24.5%), with Northland leading on the development, construction, and operation.

About the project

Set in an area approximately 5-13 kilometres off the west coast of the Isle of Lewis, the site of ‘Spiorad na Mara’ (Scottish Gaelic for Spirit of the Sea) neighbours the unique coastline of western Lewis. This area has deep connections with the seafaring industry. The wind farm’s brand identity is a tribute to the lives which were spent at sea in the Outer Hebrides. To this day, working at sea is a popular vocation in these communities. 

The figurehead is a visual reference to some important characters in Hebridean folklore. The Seelie Faeries were said to inhabit the lochs and seas of Lewis, and protect humans. As recently as the nineteenth century, local sea men would offer libations to faeries before a trip to sea, sometimes walking into the water with a cup of brewed ale. Spiorad na Mara’s figurehead encapsulates the deep connection that local people share with the environment. It personifies the past and future relationships between Scotland, its people, its stories, and its seas.
