Location 13-23km off the Sussex coast Site area 167km2 to 139km2 Water depth 19-50m Installed electrical capacity Up to 700 megawatts (MW) Turbine size Turbines will have a generating capacity of between 3MW and 7MW, with respective maximum height to tip of 180m and 210m. Turbine numbers 100 to 175 turbines, depending on the turbine size selected. For larger turbines, the number of turbines needed to generate the maximum output of 700MW would vary, e.g. 140 x5MW or 116 x 6MW turbines. Onshore Works A 26.4km underground cable route from landfall (where the electricity comes ashore) to the 400 kilovolts (KV) substation (owned by National Grid), around 2km south-west of Bolney village. Power Output Based on our current expectations of the area’s wind resource over the long-term, we estimate the site could generate more than 2,100 gigawatt hours (GWh) of electricity each year.* This is enough to power the equivalent of around 450,000 homes^, more than two-thirds of the homes in Sussex,# including the city of Brighton and Hove. Ownership Development in partnership with The Crown Estate to the point of consent. Construction and operation will be 100% owned by E.ON Climate & Renewables.
Please see our Rampion Project Update (April 2013) for a presentation of our proposals including:

* Based on wind speed data from our existing offshore wind farms in UK waters. This will be updated as Rampion site specific data is gathered from the met mast.
^ Based on an average annual domestic household electricity consumption of 4,700kWh (DECC).
# Office of National Statistics census data.We're developing initial proposals for an offshore wind farm located around 13km off the Sussex coast at its nearest point.
