About wind power Completing a Wind Power Plant

Wind power, changing the present of energy to support the future. Wind is an inexhaustible resource that is active both day and night, and wind power is attracting more and more attention as a form of reusable energy that can support the future.

Example launch: Rokkasho Village Wind Power Plant

Rokkasho Village Wind Power Plant

Wind power development with consideration for wind conditions, the power transmission environment, and the ecosystem At Japan Wind Development, we gather our group’s technology and expertise to develop environmentally friendly wind power facilities that enable stable operation in the long term. One such facility is Rokkasho Village Wind Power Plant.

Installation location selection conditions

Year-round wind activity that is suitable for power generation
Wind energy is proportional to the cube of the wind speed, therefore the stronger the wind, the more power the wind turbines can generate. When selecting a site for wind turbines, it is preferable that it has even slightly favorable wind conditions.
Allows transporting/unloading of wind power equipment
It is necessary to secure a conveyance route with roads and bridges that allow the transport of huge, heavy towers and blades that may reach 35 meters in length.
Connectability with power-transmission lines
The electric power generated by the wind is transmitted via power-transmission lines. Because wind power is a form of clean energy driven by natural wind resources, the power output fluctuates depending on wind conditions. Interconnection with the existing electric power system is necessary to provide a stable supply of electricity.
No impact on the surrounding environment
It is essential that the wind power facilities do not impact the ecosystem of endangered species.

From construction to completion

  • 1
    Draining (unloading)
    Draining (unloading) Blades, nacelle, rotors, and towers that were carried by ship are carefully unloaded in the port.
  • 2
    Foundation works
    Foundation works Deep underneath the ground, reinforced steel rods are laid out and concrete is used to create a sturdy and strong foundation.
  • 3
    Transporting wind turbines
    Transporting wind turbines The long blades and other equipment cannot be disassembled. They are slowly and carefully transported from the port to the construction site at night so as not to inconvenience general vehicles or local roads.
  • 4
    Mounting the tower
    Mounting the tower After fixing the tower securely to the foundation with bolts, a giant crane is used to lift the three sections of the tower to a height of about 83 meters, and connect each of the parts.
  • 5
    Lifting the nacelle
    Lifting the nacelle The nacelle is attached on top of the tower.
  • 6
    Lifting the rotor
    Lifting the rotor The blades are carefully attached to the rotor on the ground, and then the rotor is carefully lifted.
  • 7
    Attaching the rotor
    Attaching the rotor Once the rotor is lifted into position, it is carefully attached to the nacelle and fixed firmly in place with bolts.
