Navitus Bay's planning application will include a range of turbine sizes, heights and quantities. This principle is known as the ‘Rochdale Envelope’ and is a well-established approach to planning consent for offshore wind parks in the UK. It is important that flexibility is allowed for the final configuration given that turbine technology is evolving at such a rapid pace.
This approach fixes key parameters, such as the maximum number of turbines, maximum dimensions and the maximum installed capacity of the project. It uses these parameters to assess the realistic worst case scenario. Whilst being robust when assessing potential environmental impacts, it allows us to construct the most efficient scheme available.
The total area of seabed that will be developed is 175 square kilometres (67 square miles).
This ranges from 30 metres to 53 metres.
Number of turbines
Between 136 and 218.
The greatest number of turbines relates to the smallest size of turbine (5MW) whilst the smallest number of turbines relates to the greatest size (8MW).
Size of turbines
A maximum tip height of 200m and maximum rotor diameter of 176m (for an 8MW capacity turbine). Currently a 5MW turbine would be up to 177m to tip with a rotor diameter of 154m.
An approximate installed capacity of 1100MW.
In a typical year it is estimated that the Navitus Bay Wind Park could generate 3.3 terrawatt hours (TWh) of electricity a year. This is the equivalent of generating enough electricity for around 790,000 average UK households.
Based on DECC’s 2005-2011 average annual domestic household electricity consumption of 4,266kWh.
The figure has been calculated with a site-specific capacity factor of 35%.
CO2 emissions avoided
Approximately 1,150,000 tonnes of carbon dioxide per year.
Based on a figure of 339g CO2/kWh, calculated using Renewable UK’s “CO2 Reduction (pa) in Tonnes” methodology. View source
