Navitus Bay Wind Park was a proposed 970 MW Round 3 offshore wind farm, to be situated off the English coast approximately 10 km south of Dorset and the Isle of Wight. The wind farm was refused planning permission in September 2015.
Eneco Energie was awarded seabed land rights to develop a Round 3 offshore wind farm by The Crown Estate in 2010. Initial estimates were that around 30% of the 723 km2 (279 sq mi) zone could be used for wind farm development, giving a capacity of ~900 MW. An initial "Zone Appraisal and Planning" (ZAP) report was published in December 2010. The report proposed a single 77 square miles (200 km2) wind farm located in the middle northern part of the development zone, over 8 miles from both Durlston Head (Isle of Purbeck), and The Needles (Isle of Wight), with water depths of 28 to 55 metres (92 to 180 ft). In 2011 the name "Navitus Bay" was chosen by a public poll conducted by Eneco. Eneco (Eneco Wind UK Ltd) and EDF Energy formed a 50:50 joint venture in 2012 to develop the project.
By mid-2012 a cable landfall location had been selected at Taddiford Gap between Barton on Sea and Milford on Sea; with an underground onshore cable route of approximately 35 kilometres (22 mi) connecting to a new substation at Mannington, where a connection at 400 kV to the existing National Grid would be made. (agreed with National Grid October 2011.)
In December 2012, after public consulation, the wind farm was reduced in size from 76.4 to 67.5 square miles (198 to 175 km2) to reduce visual impact from coastal areas, with the maximum number of turbines cut from 333 to 218, and the maximum turbine height reduced from 210 to 200 metres (690 to 660 ft). The reduced wind farm had an estimated maximum capacity of around 1100 MW. Design expectations were for turbines of 5 to 8 MW capacity, foundation design was not finalised, but monopile foundations had been excluded from use in the southern half of the site. The offshore development would also include up to three (33 or 66 kV to 132 or 275 kV AC) offshore substations, and a meteorological mast.
