East Anglia ONE offshore wind farm
North Sea, off the Suffolk coast, UK · 2017–2020 (fully operational 2020) · £2.5 billion
The judgement call
Account-gated at launchThe project was a significant step in the UK's offshore wind development, demonstrating the successful deployment of large-scale wind farms. - The use of 7 MW turbines was a key decision to maximize energy output and efficiency.
Key engineering challenges
Installation of 102 large turbines and associated infrastructure in a challenging offshore environment. - Optimizing cable routes and grid connection for efficient power transmission. - Managing the logistics of a large-scale construction project far from shore.
