The Dogger Bank development now consists four offshore wind farms, each with an onshore grid connection and a capacity of up to 1.2GW. These wind farms will individually comprise some hundreds of wind turbines (depending on the size of turbines selected), offshore substations, export cables, onshore converter stations and associated infrastructure.
Each project has received its own development consent order from the National Infrastructure Directorate (NID) of the Planning Inspectorate following a thorough Environment Impact Assessment (EIA) as well as specific stakeholder and community consultation activities.
Key facts per 1.2GW project
Distance from shore: At least 80 miles (131 kilometres)
Turbines: up to 200 (all with fixed foundations)
Converter platforms: One offshore high voltage direct current (HVDC) converter platform
Collector platforms: Up to four offshore collector platforms
Office accommodation: Up to two offshore accommodation or helicopter platforms with fixed foundations
Meteorological monitoring stations: Up to five
Onshore HVDC: Underground high voltage direct current (HVDC) export cables running from shore to a converter station
Onshore HVAC: Underground high voltage alternating current (HVAC) export cables running the converter stations to the existing National Grid substation
Electricity production: 4 terrawatt hours (TWh) of green energy per annum, equal to the amount used annually by approximately one million British homes.*
CO2 reduction: Each 1.2GW Dogger Bank wind farm would reduce CO2 emissions by almost two million tonnes per annum, based on the current UK energy mix and a capacity factor of 40%.
* This is calculated using the most recent statistics from the Department of Energy and Climate Change showing that annual UK average domestic household consumption is 4,115kWh
