Wind Turbine Construction: Time Lapse Video

The easiest way to understand the onshore wind turbine construction process is to watch how it happens on YouTube.

A great example by MidAmerican Energy Company shows the three-week installation process compressed to less than six minutes.

Onshore Wind Turbine Construction: Video Summary

  • In this installation, 40-100 Geopiers were installed to improve ground stability.
  • Ground excavated 10 ft deep and 100 ft wide.
  • Base layer of concrete poured.
  • Steel rebar installed.
  • Up to 96,000 lbs of reinforcing steel installed -including a cage-like structure.
  • Concrete poured from 53 trucks – cured in 2 days.
  • 1500 tons of soil backfilled and leveled.
  • Turbine blades and tower sections delivered to site (8 truckloads).
  • Base tower lifted by crane and installed by bolting to foundations (160 bolts). Usually done using foundation bolt tensioners.
  • Mid tower lifted by crane and bolted to base tower. (Typically, this is done using pneumatic or hydraulic torque wrenches).
  • On the ground, the three blades are bolted to the hub (three hours)
  • Top tower raised and bolted to middle tower section.
  • Nacelle prepared and raised to top tower (4 hours).
  • Rotor (hub and 3 blades) raised and attached to the nacelle.
