Sofia Offshore Wind Farm

The 1.4 gigawatt (GW) Sofia Offshore Wind Farm, sited on the shallow central area of the North Sea known as Dogger Bank, is the largest project in innogy SE’s current development portfolio. The consented project is being developed 195 km off the UK’s North East coast on a site of 593 square kilometres. It has an agreed connection point at an existing National Grid substation in Lackenby, Teesside.

Sofia Offshore Wind Farm is one of the four Dogger Bank projects that were awardedconsent in 2015. Formerly known as Dogger Bank Teesside B, the project was taken over 100% by innogy in August 2017 and subsequently renamed Sofia Offshore Wind Farm.  To view the project documents on the Planning Inspectorate website click here.

The project is currentlyprogressing through the latter stages of development and design, working closely with potentialsuppliers, stakeholders, statutory bodies and the authorities. The sheer scale and size of Sofia Offshore Wind Farm will offer significant economic opportunities for the UK with potential supply chain benefits, infrastructure and associated jobs and contracts.

Having won a Contract for Difference (CfD) in the UK Government’s 2019 auction the project will now move towards a final investment decision, expected in 2020. On the current programme, the onshore civil works for Sofia are set to start in 2021 along with fabrication of the wind farm components. Offshore construction is due to start from 2022.

In terms of components, the wind farm could comprise up to 200 turbines, offshore converter stations and hundreds of kilometres of both inter-array and export cables, as well as onshore electrical infrastructure.
