The wind farm has Japan's largest wind power generation capacity
of 30 MW with 14 units of 1.65 MW turbines and 5 units of 1.5
MW turbines.
Estimated annual power generation amounts to 58.97 GWh that
can supply about 16,000 households with electricity.

Features of Equipment, Systems and Facilities
Japan's largest wind farm
The worldwide trend of wind power generation system is to
larger capacity. The Wind Villa adopted the world's largest
wind turbines (single unit output 1.65 MW and 1.5 MW) for
commercial use. The total output is 30,000 kW. Installation
of larger scaled system is aimed at more economic efficiency
of wind power generation.
Application of wind characteristics simulation technology
Array of the wind turbines were determined based on various
analysis and evaluations on wind characteristics influenced
by the conditions of complicated landscape.
Specification of the wind farm
Total capacity of the wind farm : 30,600 kW
Capacity of wind turbine (type and control method) :
- 1.65 MW × 14 turbines (induction turbine, pitch
control)
- 1.5 MW × 5 turbines (synchronous turbine, pitch
control + variable speed control)
- Total: 19 turbines
- Tower height : 60 m
- Blade diameter : 66 m
Co-existence with the stock farm
 The
station is located in the town managed stock farm in Tomamae
