Green Investment Group to partner with Iberdrola’s ScottishPower Renewables on East Anglia ONE Offshore Wind Farm


  • Macquarie’s Green Investment Group (GIG) has entered an agreement to acquire a 40% stake in Iberdrola’s ScottishPower Renewables’ 714MW East Anglia ONE offshore wind farm
  • The partnership will be the first between GIG and Iberdrola’s ScottishPower Renewables in the UK
  • Macquarie and GIG have now supported almost 50% of the UK’s offshore wind capacity

Macquarie’s Green Investment Group (GIG) has entered into an agreement, subject to the satisfaction of customary completion conditions, to acquire a 40% stake in the East Anglia ONE (EA1) offshore wind farm from ScottishPower Renewables (UK) Limited, a subsidiary company of the Iberdrola group. GIG has secured debt financing from the market to assist in funding its investment.

The acquisition reinforces GIG’s commitment to accelerating the UK’s energy transition and brings the total capacity of UK offshore wind supported by GIG to over 5.7 GW, across 14 projects[1] – equivalent to almost 50% of the total UK offshore wind capacity in operations or construction[2].

EA1 is a 714MW development located 43KM off the UK’s Suffolk coast. The project will comprise 102 Siemens Gamesa 7MW wind turbines, which when fully operational, will produce enough green electricity to power the equivalent of over 600,000 homes annually.

While this is the first time these highly experienced partners have worked together in the UK, Iberdrola’s ScottishPower Renewables has been developing EA1 for over 10 years. In 2015, the project was awarded a Contract for Difference by the UK Government, construction started in 2017 and the project’s first turbine was successfully installed in June 2019. Full commercial operations are expected to commence in summer 2020.

The development is supporting thousands of jobs throughout the supply chain and over 50% of all project investment will be spent in the UK. All 306 glass fibre turbine blades – which are comparable in length to the wingspan of an Airbus A380 – are being manufactured by Siemens Gamesa at its state-of-the-art factory in Hull, while a number of the 90-meter-high towers are being produced by CSWind UK in Machrihanish, Scotland.
