The £3bn wind farm is being jointly developed by SSE Renewables and Repsol Nuevas Energias UK.

After the sale, SSE will own a 50% interest in the project and Repsol will hold a 25% stake.

Located in Outer Moray Firth, Scotland, the wind farm is expected to start operations in 2019.

The project’s site is situated in the Outer Moray Firth on the north-western point of the Smith Bank, about 13.5km from the Caithness coastline.

In August 2013, the Moray Council has approved to carry out the onshore transmission works related with linking the Beatrice wind farm to the UK electricity grid.

The onshore transmission works will feature about 20km of underground cable from a landfall point to the west of Portgordon and a new substation which the cable will connect to, located adjacent to the existing substation at Blackhillock near Keith.

Beatrice project director Brian McFarlane said: "The Beatrice project has continued to make significant progress since our review of offshore development projects in March this year, achieving consent and securing an Investment Contract from the UK Government.

"Whilst there is still a significant amount of work to be done, this latest milestone allows the project to continue progressing towards a Final Investment Decision in 2016. We will be working closely with Repsol, CIP and our supply chain partners, to further reduce costs and refine the development and construction programme."
