London Array Wind Farm (visible from The Bay Tree) Facts

London Array is the largest operational offshore wind farm in the world.It occupies an area of 100km2 in the outer Thames Estuary between the Kent and Essex coasts, in waters up to 25m deep.

It has 175 3.6MW turbines, which are placed 650m to 1,200m apart and have a combined capacity of 630MW. From the nearest turbine to shore is 20km

Using undersea cables, the power generated by the turbines (at 33kV) goes first to two offshore substations (where the transformers boost the voltage to 150kV) and then to a specially constructed onshore substation at Cleve Hill, near Graveney on the north Kent coast. Here the power is boosted further and fed into the 400 kilovolt (kV) electricity network.

Inside each turbine is a 70m high ladder, luckily for the technicians there is also a lift.

London Array can be seen from space and featured as the NASA image of the day on 21 January 2014: http://earthobservatory.nasa.gov/IOTD/view.php?id=82844

To the tip of the blade at its highest point, each turbine is around 147m tall.

To the tip of the blade at its highest point, each turbine is around 147m tall

Each turbine is taller than the London Eye and has a swept area of 11,300m2 – equivalent to one and a half times the size of Wembley Stadium’s football pitch.

The wind farm generates enough power for around 500,000 homes whilst displacing some 925,000 tonnes of CO2 a year.

177 monopiles were installed – one for each of the 175 wind turbines and two more for the offshore substations.

Each monopole is up to 68m tall and up to 650 tonnes in weight.

Each turbine (the bit above the transition piece) weighs around 480 tonnes.London Array has 187 array cables (connecting the turbines to each other and to the offshore substations. These are up to 3,200m in length and each metre of cable weighs 50kg.

Each of the two offshore substations weighs around 1,250 tonnes – about the same as 200 African elephants.London Array has been generating energy since October 2012 when the first turbine began produce power. It was fully operation in April 2013.
It was formally opened by David Cameron in July 2014
You could fit 7,245 Wembley football pitches inside the wind farm’s boundaries.twm4

London Array was the first Offshore windfarm in the world to achieve an annual output of more than 2TWh in a single year.

The turbines start generating electricity when wind speeds reach 3 metres per second (m/s) or around 7mph. They achieve full power from 13m/s (around 29mph).
London Array has set a new record for the amount of clean electricity produced by an offshore wind farm in a single calendar month.December 2015 saw its 175 turbines generate 369,000 MWh of electricity –the previous best of 317,000 MWh set last November.
