NSW, owned by US company General Cable, will supply 30 kilometres of medium-voltage alternating-current (MVAC) array subsea cables to the development, which lies eight kilometres off Whitstable, south-east England.
The project features 15 Vestas 3.3MW turbines — the first order for the Danish manufacturer's V112-3.3MW model, which was launched in April as a variant of the V112-3MW.
Construction of the extension will begin in mid-2015.
The existing 90MW Kentish Flats wind farm consists of 30 Vestas’ V90-3MW turbines, which it services, and was commissioned in 2005. It is also operated by Danish utility Vattenfall.
