German energy group innogy has officially inaugurated the 353MW Galloper offshore wind farm, located 27km off the Suffolk coast in London.

Built with an investment of £1.5bn, the wind farm is expected to generate enough green power to meet the annual electricity needs of more than 380,000 UK households.

“Galloper will significantly contribute towards the decarbonisation of the UK’s energy supply.”

Galloper wind farm is jointly owned by innogy (25%), Siemens Financial Services (25%), Sumitomo Corporation (12.5%), ESB (12.5%) and a consortium managed by Green Investment Group and Macquarie Infrastructure and Real Assets (25%).

Innogy, which led the development and construction of the Galloper project, will operate the wind farm on behalf of its project partners.

innogy Renewables COO Hans Bünting said: “I am extremely proud to inaugurate Galloper Offshore Wind Farm, the fifth offshore wind farm that innogy has constructed in the UK.

“Offshore wind is now a key industrial sector for the UK and offers particular opportunities to key regional hubs, such as East Anglia – the home of both Galloper’s construction base and its operation and maintenance facility.”

Galloper has an expected operational lifetime of more than two decades and will significantly contribute towards the decarbonisation of the UK’s energy supply.

The wind farm was fully commissioned in spring this year, and is said to have created 700 employment opportunities.

Bünting further added: “With all our projects, we always strive to invest in local businesses and during its operating lifetime, almost 60% of the investment in Galloper is expected to go to UK companies.

“At innogy, we look forward to continuing to play an active role in the impressive UK offshore wind story. We have recently begun construction, together with our partners, on our sixth and largest offshore wind project to date, the 860MW Triton Knoll.”

Last month, Tendring District Council and the Marine Management Organisation approved construction of the operations and maintenance base for the wind farm in Harwich International Port, Essex.
