Project Details for Galloper Wind Farm
General Information Name Galloper Wind Farm correct
Other names correct
Country name United Kingdom correct
Region England, East of England correct
Comments Part of the Round 1 and 2 extensions with an extra 1.7 GW supplied. Two 3.6MW turbines are under consideration with 107 and 120m rotor diameter, although a turbine up to 7MW could be used.

Up to 3 met masts.

In November 2013 the capacity was lowered from 504MW to 340MW. The reduction was announced by SSE and the reasoning was that it was to obtain the most efficient and viable scale for the project.

An application has been submitted for an Investment Contract under the EMR framework.

April 2014 - SSE's and RWE's investments in DEVEX to date total £30m
correct
Round (or category) Round 2.5 correct

Comments on the status March 2014 SSE stated it would not continue with the project into the construction stage.

October 2014 RWE stated that it would not continue with the project.

Subject to full planning consents including Environmental Impact Assessments (EIA).

Following an Appropriate Assessment, changes were made to the Order by the Secretary of State to mitigate likely adverse affects on Lesser Black Backed Gulls, a qualifying feature of the Alde-Ore Estuary SPA and Ramsar sites.
