Offshore Wind

East Anglia ONE

16 July 2021

In August 2019, GIG acquired a 40% stake in the 714 MW East Anglia ONE offshore wind farm in our first transaction with Iberdrola, adding to our extensive UK offshore wind portfolio.

Key data

714 MW

EA1 is one of the largest offshore wind farms in the world

102

Siemens Gamesa 7 MW turbines covering an area of c. 300 km2 in the North Sea

630,000 homes

The project will produce enough clean electricity to power the equivalent of almost 630,000 British homes

Opportunity

Located in the North Sea about 43 km off the coast of Suffolk, EA1 had been in development by Iberdrola’s ScottishPower Renewables for over 9 years before GIG began discussions to partner on the delivery of EA1.

EA1 is one of the largest offshore wind farms in the world and is a key project in the UK progressing towards Net Zero by 2050 and reaching the UK’s target of 40 GW of Offshore Wind by 20301.

This project further strengthened GIG’s commitment to the UK offshore wind sector and brings the total capacity of UK offshore wind supported by GIG to over 5.7 GW, across 14 projects2 - equivalent to almost 50% of the total UK offshore wind capacity in operations or construction3.

In 2020, GIG brought an additional investor into its holding company owner of 40% of EA1.

Actions

In partnering with Iberdrola on the delivery of EA1, we brought our extensive experience and substantial knowledge of the UK offshore wind sector to the project.

We structured innovative financial and risk management solutions to support our project investment and mitigate macro risks, and negotiated several key transaction contracts with SPR and the Iberdrola Group prior to joining in August 2019.

The EA1 construction continued throughout a challenging 2020, with all turbines successfully commissioned by July 2020 despite the COVID challenge.

"East Anglia ONE is a world class development delivering a huge range of benefits to communities across the UK, and I’m delighted that GIG is partnering with ScottishPower Renewables and the Iberdrola group on the project.

The UK continues to be a world leader in offshore wind, and I’m incredibly proud of the pioneering role GIG has played in the creation of that market.  We’re committed to driving the UK’s energy transition, establishing offshore wind as the backbone of the UK’s new low-carbon energy system."

Impact

The EA1 project has supported thousands of jobs across the offshore wind supply chain. All 306 glass fibre turbine blades were manufactured by Siemens Gamesa at its state-of-the-art factory in Hull and a number of the 90-meter-high towers were produced by CSWind UK in Machrihanish, Scotland.

714 MW EA1 generates enough green electricity to power over 630,000 UK homes, reducing greenhouse gas emissions by 979 kt CO2e per year. That is the equivalent of removing over 323,763 cars from the road.
