Humber Gateway, Environmental Statement

The proposed Humber Gateway Offshore Wind Farm is located north of the mouth of the River Humber, within an area of sea approximately 8km off the Holderness Coast of East Yorkshire. Depending on the capacity of the turbines, the wind farm will consist of between 42 and 83 turbines. The proposal also includes an offshore substation, up to three meteorologicals mast, inter-array cables and subsea export cables (that will come ashore near Easington).

An underground cable is proposed from Easington to Salt End (a distance of around 30 km) to enable the electricity to be connected into the National Grid at a proposed new substation at Salt End, on the east side of Hull.

The operational life of the project is expected to be 40 years (in line with the Crown Estate lease). After 20 to 25 years, re-powering (i.e. replacing the wind turbines at the end of their economic life with new turbines) may be necessary, but this will be subject to further environmental studies and further marine consents.

A full description of the offshore elements of the project (up to Mean High Water Springs) is presented in Section 6 of this Environmental Statement. The onshore elements of the project are described in a separate Environmental Statement which covers the underground cable works above Mean High Water Springs.
