Construction work on the 54 turbine wind farm began last summer and is expected to be complete by Summer 2017. The existing Clyde Wind Farm already has 152 turbines.
The first phase of the turbine erection process has begun, with the pre-assembly crane installing the bottom two tower sections. Each turbine has four tower sections; a nacelle at the top with a hub and the rotor.
The remainder of each turbine will be erected using the main crane which is scheduled to arrive mid-September and following the complete erection, commissioning works will then be undertaken ahead of generation.
Clyde Wind Farm (Scotland) Ltd is owned by SSE, Greencoat UK Wind and GLIL. The Perth-based utility, along with turbine supplier Siemens, commissioned a study to ascertain the impact of Clyde Extension on both the Scottish and UK economies.
An SSE spokeswoman said: “The windfarm represents a £108 million contribution to the UK economy and manufacturing and maintaining the turbines contributes £53 million.”
The report also found that 71% of the contribution to UK employment from the turbines will stay within Scotland, and around 74% of the UK employment from the construction phase will be Scottish.
