A 2,000 tonne offshore substation has been installed at a wind farm off the Sussex coast.

The structure at the 400MW Rampion wind farm will eventually transform the electricity generated by the planned 116 turbines at the site from 33kV up to 150kV.

This will allow the facility to provide enough electricity to supply almost 347,000 homes a year, equivalent to around half the homes in Sussex.

The site is currently being built by E.ON, the UK Green Investment Bank and Enbridge, a Canadian energy firm.

After taking approximately two years to design and build, the offshore substation was transported 500 miles by sea from where it was made in Scotland to Southampton, before being towed out to its final location.

The turbine installation began last month and to date, eight are fully installed. The project is due to be completed and fully operational in 2018.

Chris Tomlinson, Development and Stakeholder Manager for the Rampion Offshore Wind Farm, said: “The offshore substation is the largest and most complex component of the wind farm to be installed offshore and a great amount of skill was required by the engineers, crane operators and vessel operators to lift and position the 2,000 tonne structure into place.”

Global offshore wind capacity is set to triple in the period between 2015 and 2020.
