Hornsea One offshore wind

North Sea off the Yorkshire coast

The government’s 2016 announcement described the planned Hornsea One project and its electrical capacity. Offshore siting links wind resources with marine space, cable connections and maintenance access.

A historical “largest” label belongs to its date. Capacity is a maximum output rating, not the energy generated every hour.
