Technicians sit in the transition piece (the 'join' between foundation and turbine tower) waiting for the first tower section to be delivered. The Ormonde windfarm has been built in the Irish Sea, 10km off Barrow-in-Furness. It comprises 30 5MW wind turbines with the capacity of 150 megawatts. It is expected to produce around 500 gigawatt hours of electricity every year, enough to supply the equivalent of approximately 100,000 homes per year with clean power
