Our operations

Key facts

• Approximately 27km (16.8 miles) from the North Norfolk coast at Blakeney Point and approximately 28km (17.4 miles) from the Lincolnshire coast at Chapel St Leonards.
• Between 88 and 206 turbines (depending on size and capacity of turbine used) in 4 – 22m of water.
• A maximum potential capacity of 620MW – Turbines have not yet been chosen but would be in the region of 3MW to 6MW.
• Turbines are likely to have a maximum hub height of 110m and a maximum rotor diameter of 140 m.
• Underground cables between the turbines and the shore.
• Up to three offshore substations and connection to the National Grid.
• A designed operational life of 20 / 25 years.
• Zero CO₂ emissions from power generation.
• Based on currently available data and an assumption that the maximum capacity of 620 MW would be installed, it is estimated that the wind farm could supply the equivalent annual demand of around 420,000 households. If, following site investigations and identification of further constraints, the number of turbines that could be feasibly constructed was reduced, the associated benefits would fall, in line with the actual installed capacity. Centrica will keep these figures under review and publish updated estimates on its website and in other publications such as project newsletters, as more information is available.
