REALIZATION PROCESS

Preliminary studies, wind data gathering, site conditions survey, power system connection conditions, and regulations

Preliminary checklist

Wind Resource

Utilizing NEDO's wind resource map, check average wind speeds and wind directions for potential sites.
Conduct wind condition analysis and confirm extreme wind speeds through typhoon simulations.

Site Conditions

• Distance to the nearest residential buildings
• Distance to the transmission and distribution lines (in case of total power is below 2MW, the system is connect to the nearest utility line)
• Regulations such as national or municipal parks, forests, and other restricted areas
• Environmental assessment (noise, ecosystems, landscape, electromagnetic waves, shadow flicker, etc.)

Site Area

(For example, for one unit of KWT300 (300kW), land area should be 30 x 40 (m))

Transportation Conditions

Check and confirm transportation conditions suitable for delivery of components using maps or alternative methods

For self-consumption case, the facility's electricity consumption patterns

Feasibility Study and Cost Estimation

• Siting and wind turbine specification determination utilizing wind resource data
• Calculation of power generation and construction costs, evaluation of business feasibility, and making the decision on the wind turbine installation

Wind monitoring data acquisition (at least 1 year), power system interconnection study

Applying to the power company or authority in charge on the conditions for connection of generated power to the transmission grid

System Implementation Design

Detailed Design of Wind Turbine / Geological Survey and Foundation Design / Development of Construction Plans, etc.
