Scotland is emerging as one of the most important offshore wind markets in the world. As of 2025, the country operates nearly 3 GW of offshore wind capacity across nine wind farms. This momentum consists of a wider offshore wind pipeline shaped by the ScotWind and INTOG leasing rounds from the Scottish government.

Several upcoming offshore wind projects in Scotland, including Berwick Bank Offshore Wind Farm, Marram Wind Floating Offshore Wind Farm, West of Orkney Offshore Wind Farm, and Stromar Floating Offshore Wind Farm, rank among the largest developments planned in Scottish waters.

This article explores Scotland’s largest upcoming offshore wind farm projects, providing details about their scale, location, development status, and strategic importance. 

Largest Upcoming Offshore Wind Farm Projects in Scotland

Berwick Bank Offshore Wind Farm

Berwick Bank Offshore Wind Farm is the biggest offshore wind project planned in the outer Firth of Forth in the North Sea, with an installed capacity of up to 4.1 GW. If delivered at full scale, it would rank among the largest offshore wind farms globally and generate enough clean electricity to power more than six million homes, roughly twice the number of households in Scotland. 

The project developed by SSE Renewables is now at an advanced stage. In summer 2025, the Scottish Government approved Berwick Bank’s Section 36 consent, clearing a key regulatory milestone. The wind farm has secured two grid connection points, one in East Lothian and another near Blyth in Northumberland, and could begin generating power in the second half of this decade. 

Once operational, Berwick Bank could increase Scotland’s total renewable energy capacity by nearly 30% and play a central role in meeting the country’s offshore wind target of up to 11 GW by 2030. The project could also avoid around eight million tonnes of CO₂ emissions each year, comparable to removing all of Scotland’s annual car emissions.

Marram Wind Floating Offshore Wind Farm

MarramWind is a proposed 3 GW floating offshore wind farm planned around 75 kilometres off the Aberdeenshire coast in northeast Scotland. Developed by ScottishPower Renewables, the project targets deep waters averaging 111 metres, where floating wind technology is essential. 

ScottishPower Renewables took full control of MarramWind in late 2025 after acquiring Shell’s stake, following the ScotWind leasing round awarded in 2022. The project remains in early development, with work focused on seabed surveys, environmental studies, and stakeholder engagement. 

Once built, MarramWind could generate enough clean electricity to power more than 3.5 million homes and will be one of the largest offshore wind farms in the UK.

West of Orkney Offshore Wind Farm

The West of Orkney Windfarm is one of the largest upcoming offshore wind projects in Scotland planned around 30 kilometres west of Orkney and roughly 25 kilometres from the north Sutherland coast. Designed for a capacity of about 2 GW, the project is expected to deliver first power by 2030 and could supply electricity to more than two million homes. 

The project secured an Option Agreement through the ScotWind leasing round in January 2022 and has since achieved a key milestone by receiving both offshore consent from Scottish Ministers and onshore planning permission in principle from The Highland Council. This makes West of Orkney the first ScotWind project to gain approval for both offshore and onshore works. 

The site sits within the Scottish Government’s N1 Plan Option, identified as suitable for large-scale offshore wind development. The development also holds a grid connection agreement for Caithness.

Stromar Floating Offshore Wind Farm

Stromar is a proposed floating offshore wind farm off the coast of Caithness in northern Scotland, around 50 kilometres east of Wick. The project targets a capacity of up to 1.5 GW, enough to supply clean electricity to around 1.5 million homes. Stromar is located in waters 60 to 100 metres deep and covers a seabed area of about 256 square kilometres.

The project is being developed by Stromar Offshore Wind Farm Limited, a joint venture between Ørsted, BlueFloat Energy, and Nadara, under a ScotWind Option Agreement awarded in 2022. Stromar remains in early-stage development, with extensive surveys completed and environmental impact assessments underway. 

Construction is expected to begin around 2028, with commercial operations targeted between 2030 and 2033.

Inch Cape Offshore Wind

Inch Cape is one of Scotland’s new offshore wind farms, with an installed capacity of almost 1.1 GW. Now under construction, the project will install 72 turbines in the North Sea around 15 kilometres off the Angus coast, covering an offshore area of about 150 square kilometres. 

Electricity from the wind farm will be collected at a single offshore substation and transmitted 85 kilometres via subsea export cables to landfall at Cockenzie in East Lothian. From there, power will pass through a new onshore substation built on the former Cockenzie Power Station site before entering the national transmission system. 

The wind farm will be operated and maintained from a purpose-built facility at Montrose Port and is being developed by Inch Cape Offshore Limited, a joint venture between Red Rock Renewables and ESB. In December 2025, China’s CNOOD-Wenchong Heavy Industries (CWHI) shipped off the final eight XXL monopiles, completing the delivery of all 32 monopiles it was contracted for.

Once fully operational in 2027, Inch Cape will deliver large-scale renewable power from turbines standing up to 274 metres tall, installed on a mix of monopile and jacket foundations in water depths of 34 to 64 metres.

Green Volt Floating Offshore Wind Farm

Green Volt Offshore Wind Farm is a 560 MW floating offshore wind project being developed by Flotation Energy and Vårgrønn, around 80 kilometres off the coast of Scotland. The project secured seabed rights through the INTOG leasing round in 2022 and later won a Contract for Difference in the UK’s AR6 auction, with 400 MW awarded at a strike price of GBP 139.93 per MWh.

Development has moved steadily from planning to delivery, with key engineering contracts now being issued. Worley holds the FEED contract for the onshore substation, while OWC is providing cable engineering support. Once operational, Green Volt is expected to save around one million tonnes of CO₂ each year, unlock EUR 2.5 billion in private investment, and create up to 2,800 jobs.

The project will also supply clean power to offshore oil and gas platforms, supporting decarbonisation in the North Sea. The wind farm project is designed to deploy up to 35 floating turbines. Green Volt targets first power by 2029 and is positioned as one of the world’s first commercial-scale floating wind farms.

Nomadic Floating Offshore Wind Farm

Nomadic Offshore Wind is a proposed 500 MW floating offshore wind project planned for the Irish Sea, between Northern Ireland and Islay, Scotland. The project is led by Simply Blue Group, which is partnering with MJM Renewables to advance development. Currently at the announced stage, Nomadic is expected to begin construction in 2026 and reach commercial operation by 2030.

The project will use floating wind technology, allowing turbines to operate in deeper waters away from shore, shipping routes, and fishing grounds. In addition to supplying clean electricity for around 40,000 households, the developers are exploring multiple routes to market, including green hydrogen and e-fuels production, data centres, and energy-intensive manufacturing in Northern Ireland.

Conclusion

Scotland’s upcoming offshore wind projects signal a decisive shift toward utility-scale deployment and floating wind leadership. Developments such as Berwick Bank, MarramWind, West of Orkney, and Stromar highlight the country’s move beyond early offshore success toward projects capable of powering millions of homes.

This growth is supported by strong government policy and a seabed leasing strategy. Through ScotWind, around 29.3 GW of new capacity has already been allocated, including 18.5 GW dedicated to commercial-scale floating wind, the largest such leasing round globally.

The INTOG programme adds a further 5.4 GW to decarbonise offshore oil and gas operations while advancing floating wind technology. Supported by an updated Sectoral Marine Plan targeting more than 45 GW of offshore wind by 2035, Scotland is positioning itself as a global hub for offshore and floating wind development.
