Triton Knoll is a proposed offshore wind farm located off the east coast of England, approximately 20 miles off the coast of Lincolnshire and 28 miles from the coast of North Norfolk.
The exact size of the project is not determined, but if granted consent to go ahead, Triton Knoll could generate up to 900MW of renewable energy. This could provide enough renewable electricity to meet the average needs of up to 800,000 average UK households each year.1
Triton Knoll represents a multi-billion pound investment in clean green UK energy infrastructure. Although Triton Knoll is still in the development phase, over £18 million has already been invested in the UK as a result of this project with £1.75 million invested in the East Coast of England. It is anticipated that a substantial proportion of contracts associated with the construction of Triton Knoll would be awarded to UK companies.
Triton Knoll Offshore Wind Farm is being developed as two separate packages:
The Offshore Array– the wind turbines, meteorological masts, offshore substations and the cables that link the wind turbines to the offshore substations.
The Electrical System - the substation, underground cables, the offshore export cables an electrical compound along the onshore cable route.
Following a recent project review and offshore site investigations we have revised plans for the proposed Triton Knoll Offshore Wind Farm project.
RWE Innogy UK (formerly RWE npower renewables) will progress Triton Knoll with a reduced capacity of up to 900 megawatts, rather than the maximum of 1200 megawatts. The new capacity would ensure enough energy to power the equivalent domestic needs of up to 800,000 average UK households.1
This revised site design would ensure the efficiency of the site is maximised whilst the cost of the energy is minimised.
This revised capacity also means significant reductions to the required onshore footprint. A maximum of 8.6 hectares would now be needed for the onshore substation rather than 20 hectares and up to 1.8 hectares would be needed for the intermediate electrical compound rather than 3 hectares.
Work is still progressing on developing the proposed electrical infrastructure. Local communities will have further opportunity to have their say on this during consultation which will take place before any planning application is submitted.

1. Energy predicted to be generated by the proposal is derived using long term wind speeds calculated by meteorological models seeded with historical weather data obtained from satellite, surface-based and airborne measurement systems. This enables a calculation to be made to estimate the average annual energy production for the site based on 150 turbines each of rated capacity 6 MW. The energy capture predicted and hence derived homes equivalent or emissions savings figures may change as further data are gathered. Equivalent homes supplied is based on an annual electricity consumption per home of 4500 kWh. This figure is supported by recent domestic electricity consumption data available from The Digest of UK Energy Statistics and household estimates and projections from the UK Statistics Authority.
