Renewables First – Assembling the Baulker Farm wind turbine blades.

Whilst the turbine tower, nacelle and generator were being installed, a simultaneous job at ground level involved assembling the hub and wind turbine blades.

The picture (below left) shows the rotor hub, with the wind turbine blades being positioned for final fixing to the hub. This procedure is undertaken at ground level. In the main picture above, it is possible to see the pitch mechanisms within the hub which pivot the blades around – essentially enabling them to feather the blade either into or out of the wind in order to maximise the efficiency of the turbine.

Although normally a straightforward procedure, the challenge at Baulker Farm was one of space limitations due to the proximity of farm buildings and the large chicken sheds.  The rotor blade diameter of the EWT 500 kW turbine is 54 metres, so a large surface area was required.

In order to assemble the turbine blades the entrance to the farm was temporarily sealed off in order that the blades could extend along the entrance roads!

Once assembled, the hub and rotor blades will be lifted and attached in one manouevre.

Due to several hours delay in the arrival of the upper section of the turbine tower, lifting and fixing the turbine blades had to wait til the following morning.

The picture (below left) shows the turbine blades fixed into position by 10:00 am the next morning.

Want to install a wind turbine?

If you are in the UK then take our Wind Site Self-Assessment - Step 1 of our modular Windpower Feasibility Study. It takes about 20 minutes to work through the basic checks to see if your site might be suitable, including:

  • Estimating wind speed
  • Checking proximity of nearby properties
  • Checking site access and approach roads
  • Investigating connection with the grid

If you are in the Republic of Ireland, or overseas, the first step is to consider our modular Windpower Feasibility Study, so please Contact us to discuss your site further.
