Kentish Flats is the name of an offshore wind farm operated by Vattenfall in the south-west North Sea off the south-east coast of England, which consists of two parts. Area 1 with 30 wind turbines of the 3 MW class was the largest British offshore wind farm when it was commissioned in 2005, but was soon surpassed by other wind farms in terms of electrical output .

In 2015, the wind farm was expanded by another 15 wind turbines, each with 3.3 MW. The expansion facilities were commissioned in December 2015, and the official inauguration took place at the beginning of June 2016.

Original wind farm (phase 1)

location

The OWF Kentish Flats is located off the coast of Kent in about 5 m water depth just outside the main shipping routes of the Thames . The distance to the small town of Herne Bay to the south and the town of Whitstable is between 8.5 and 13 km, London is about 60 km away. The wind park consists of a total of five rows of six wind turbines each in an east-west orientation. The original total area of ​​the wind park is 10 km².

technology

30 Vestas V90-3MW turbines are used here , each set up 700 m apart and which were the largest turbines in Great Britain at the time Kentish Flats was built. The systems have a nominal output of 3  MW , m and a rotor diameter of 90 and a hub height of 70 m, as a foundation came Monopiles used. The switch-on speed of the systems is 4 m / s, the turbines reach their nominal output at 14 m / s, the switch-off speed is 25 m / s. The electricity generated is fed into the UK grid via submarine cables in a transformer station in Herne Bay; a transformer platform is not required due to the proximity to the coast.

Wind speed and electricity production

The average wind speed at the site is 8.7 m / s at the hub height of the systems, which means that 280 GWh of energy can be produced in an average wind year  . The capacity factor is around 35%. In 2007, the gearboxes of all 30 systems had to be changed due to faulty bearings . As a result, the actually generated feed-in fell to 200 GWh this year. The cost of the entire project amounted to 105 million pounds .

Extension: Kentish Flats Extension (Phase 2)

In February 2013, the extension of the OWF Kentish Flats by 17 more wind turbines was approved. Fifteen Vestas V112-3.3MW turbines with a rotor diameter of 112 meters and a nominal output of 3.3 MW, which were built in 2015, are now in operation. The investment volume was 170 million euros. The work should be completed in early 2016. The first system fed electricity into the grid for the first time at the end of August 2015, the last one went into operation in mid-September. The official commissioning took place in June 2016.

The systems used are based on the V112-3MW version, which has been in production for several years and which was originally intended to be used here as well. Instead, the new, more powerful V112-3.3MW model was used for the first time in the Kentish Flats OWP.
