Innogy has selected the giant Siemens Gamesa SG 14-222 DD offshore wind turbines for the Sofia OWF - the companies largest offshore wind project, located at Dogger Bank in the North Sea.

The selection is subject to a final investment decision which is expected in Q1 2021.

The SG 14-222 DD is a 262 metre tall turbine with 108 metre carbon and fibreglass blades cast in a single mould, with a 222 metre diameter rotor sweeping an area of 39,000 m2. 

100 turbines are expected to be ordered, each with a capacity to generate 14 megawatts of power. Siemens Gamesa will be contracted to manufacture and install each of the turbines. This takes the total conditional order backlog for Siemen’s flagship turbines to 4.3GW - including conditional orders for Taiwan and the USA. 

Sofia will be the first European project to use these turbines, which are expected to be market-ready by 2024. This falls in lines with Dogger Bank’s development plans which will see offshore construction of the foundations of the 593km2 offshore wind park to begin in 2023.

At roughly the same size as the Isle of Man, and with a generation capacity of 1.4 gigawatts, Dogger Bank is set to be a giant project that will deliver enough clean energy for almost 1.2 million UK homes.  

UK Minister for Energy and Clean Growth Kwasi Kwarteng said: “The UK has invested more in offshore wind than any other country and is already home to the world’s largest offshore wind farms. Now the UK will be the first European nation to boast this cutting-edge turbine technology at Sofia Offshore Wind Farm.

“Offshore wind will play a vital role in a future net-zero UK economy, and already supplies 10% of UK electricity demand - a figure we expect to double by the middle of the decade.”


Sven Utermöhlen, Senior Vice President Renewables Operations Offshore at Innogy SE said: 

“The selection of these state-of-the-art offshore wind turbines for Sofia, our largest offshore wind development project, reflects our ambition to strive for continuous innovation. Siemens Gamesa’s towering 14 MW machine is a perfect match for our flagship Sofia project, together cementing offshore wind‘s central role in the world’s clean energy future. This turbine embodies the impressive technology we need to build our ground-breaking project, that is further from shore and more technically challenging than any of its predecessors.”

Richard Sandford, Innogy's Director of Offshore Investment & Asset Management said: “The selection of Siemens Gamesa’s turbines was a long and rigorous process, and we are pleased to now be the first in Europe to commit to using this superb engineering and technology. It is also to be noted that the company is a staunch supporter of the UK’s offshore wind sector, having shown impressive commitment to the development of its own facilities and to the local supply chain. This is of utmost importance to us as we work to support the Sector Deal commitments, particularly in relation to UK content.”

Small Modular Reactors (SMRs) from 3 different suppliers will be operational this decade. NuScale 2026; GE Hitachi 2027; Rolls-Royce 2029. With 2 to 4 years build programmes, the playing field with intermittents is virtually levelled and the burden of cost-of-capital that has crucified investment in 'big nuclear' is utterly negated. Such is the investor-attractiveness of SMRs, in terms of earnings per £1.00 of capital invested, these low-carbon technologies have every chance of draining away investment in intermittents. This is particularly true of offshore wind as the overt, most technically challenging electricity generating technology of all. Considering income less all significant costs, every £1.00 invested in offshore wind will earn £0.41. Taking the GE Hitachi SMR as an example, every £1.00 invested in this SMR will earn £5.02 - 12X more. Search for: "pension pots that have gone into the £9.0 billion offshore wind farm" It is difficult to imagine how fund managers will be able to ignore the magnitude of this difference and exactly what it might mean for the future of wind and solar companies.
