The Ormonde Wind Farm, west of Barrow-in-Furness in the Irish Sea, covers 8.7 km² with a capacity of 150 MW, producing about 500 GWh annually. Originally planned as a hybrid gas-and-wind project by Eclipse Energy, it was converted to a full wind farm after Vattenfall acquired the company in 2008, with Offshore Design Engineering managing the project.

Construction ran from 2010 to August 2011, featuring 30 REpower 5 MW turbines on OWEC Tower foundations built by Burntisland Fabrications. Prysmian supplied 27 km of inter-array and 42 km of export cables, while A2SEA and Scaldis-Geosea handled installation.

Fully commissioned in February 2012, Ormonde became one of the UK’s early large-scale offshore wind farms, helping lead the shift to renewables, with an estimated levelised cost of £149/MWh.
