Our renewables success story

Celebrating our role in the UK's onshore and offshore wind farms

How we met the needs of a changing world

E.ON's history in renewable energy goes back to 1991 when we began developing our first onshore wind farm. Since then we've continued to innovate and develop wind, solar and biomass technologies to help tackle climate change and create a sustainable energy system for the future.

Over the following three decades we continued to play a role in pioneering the UK’s renewable energy future; developing our expertise and experience through a vast portfolio of both onshore and offshore wind farms across the UK, investing more than £3.3bn in UK renewables in the last ten years alone.

We were part of the consortium that built London Array, the world's largest offshore wind farm at the time it opened in 2013. And, more recently, as a partner in Rampion we built the first wind farm off the UK's south coast.

In October 2019, the majority of E.ON's wind generation business was transferred to RWE. Having driven the development of large-scale renewables for almost three decades, the future E.ON will now apply itself to tackling the challenge of helping customers become more sustainable at home and, in business, reduce their carbon footprint so we can all play our part in the smart and sustainable future energy world.

Investing in renewable energy

Providing all our residential customers with renewable electricity – a change at a scale never seen before in Britain – was driven by our £3.3bn+ investment in renewable energy in the UK in the recent years.

Onshore generation - our story

From Rhyd-y-Groes on Anglesey in 1992 to Camster in the Scottish Highlands in 2014, E.ON has built and operated onshore wind farms across Great Britain which continue to play a part in meeting the UK's net-zero carbon emissions targets.

 

The early development of onshore wind in the UK tested the technology and helped prove its viability as a vital addition to meet the UK’s energy needs. These early successes helped to build the supply chain and investment potential for future developments in the UK’s renewable energy fleet.

Offshore generation - our story

We were behind the UK's first ever offshore wind farm – the twin turbines off the coast of Blyth in Northumberland. Blyth provided a valuable testing ground that played a part in making the country's offshore wind sector what it is today. Since then we have driven some of Britain's pioneering, commercial-scale offshore wind projects, with developments off the east of England, the Thames Estuary, the south coast and the Solway Firth.

Combined, these wind farms produce enough electricity to power the equivalent of more than 1.1 million homes but play an equally positive role in proving that renewable energy works and can more than compete on cost grounds with their fossil fuel alternatives.

The future of energy is smart, personalised and sustainable, which is why we're working with our customers at home, in business and across entire communities to develop new solutions and opportunities, working together to create that new energy world.

Blyth offshore wind farm

blyth wind farm turbines

The UK’s first offshore wind farm, built one kilometre off the Northumberland coast in 2000 and decommissioned in 2019. When in operation, the two 2MW turbines generated enough power to supply over 2,000 homes and saved 4,520 tonnes of carbon dioxide from entering the atmosphere each year.

Blyth provided a pioneering contribution to renewable technology and lay the foundation for a further 600 offshore wind turbines installed by E.ON in the seas of northern Europe. Since the sites construction, the area has become a valuable testing ground for offshore construction, operations and maintenance and is today a hub for offshore innovation and development.

Stags Holt wind farm

stags holt wind farm

This 18MW site near March in Cambridgeshire went into operation in 2007 and has the capacity to supply around 10,000 households with electricity, saving over 2,300 tonnes of carbon emissions each year each year.

Ovenden Moor onshore wind farm

A joint venture between E.ON and Energy Power Resources Ltd, located near Halifax in West Yorkshire, Ovenden Moor was repowered in 2017 when the original wind farm which had supplied power for over 22 years was decommissioned.

With the development in technology since the site was first built, the original 23 turbines were replaced with nine new turbines capable of producing twice as much power.

Humber Gateway offshore wind farm

humber gateway wind farm

In spring 2015 this 73 turbine, 219MW project located 8km off the Holderness coast began generating electricity two months ahead of schedule.

Construction of the site helped bring significant investment to the area as E.ON invested £4m in transforming a neglected derelict site at Grimsby Fish Docks into the wind farm’s Operation and Maintenance base and in improving the surrounding quayside for its vessels.

Today the site provides enough power for around 170,000 homes, equivalent to around one and a half times the size of Hull.

Holmside, Harehill and High Volts

Holmside wind farm

Located in County Durham, Holmside, Harehill and High Volts were all commissioned in spring 2004. At the time of their constructions, these wind farms boasted the most powerful wind turbines in the UK, which were transported from Hartlepool docks in sections on vehicles up to 50m long.

A locally based company, AMEC Wind Services, developed the site and also helped manage the project during construction. 

Robin Rigg offshore wind farm

Robin Rigg wind farm

Completed in 2010, Robin Rigg was the first commercial wind farm to be constructed in Scottish waters.

The 174MW £325m project is located in the Solway Firth a sandbank off the south west coast of Scotland between Galloway and Cumbria.

Camster onshore wind farm

Located in Caithness in the Scottish Highlands, Camster became operational in 2014. The 25 turbine, 50MW site has the capacity to supply over 40,000 homes and save around 55,000 tonnes of carbon dioxide over its lifetime. 

Rampion offshore wind farm

rampion wind farm

Opened in 2018, the Rampion wind farm sits 13km off the Sussex coast and generates enough energy to power about 350,000 homes. 

After a three-year construction period, its 116 turbines, cover an area larger than Guernsey. 140km of cables are buried under the seabed to connect the turbines and to carry the power back to shore. 

Scroby Sands offshore wind farm

scroby sands from the beach

Commissioned in 2004, Scroby Sands was the first UK commercial offshore wind farm to be given consent.

Consisting of 30 turbines, the £75m project located 3km off the coast of Great Yarmouth generates enough electricity to power over 40,000 homes. 

Along the esplanade a visitor centre attracts around 30,000 visitors each year who come to enjoy the interactive activities and displays and learn about renewable energy.
