Wind Turbines

Economics

Manufacturing
Structure
Controls
Installation

2 blades vs. 3 blades = lighter, simpler, cheaper mechanism
No need for main shaft or main bearing - fewer pitch bearings
No need for mechanical yaw brake system
Lighter tower, saves on materials and foundation

Single unit (1MW) saves an estimated manufacturing cost over $335,000 USD
50MW wind farm could save an estimated $11,000,000 USD.

Utilizing lighter, smaller crane and single lift, installation cost per wind turbine saves approximately $2,200 USD.

Proprietary technology extends the life of wind turbine and decreases downtime

The uptime availability of GC China’s wind turbine consistently achieves 97%. 2%-3% higher than 3-bladed wind turbines.
Annual revenue increases about $17,000 to $34,000 USD for a single unit.
Annual revenue increases about $774,000 to $1,682,000 USD for 50MW wind farm.

Technology	Features	Extended Life
Soft Design	Teeter-styled hub	Improves the life of transmission chain, tower, etc.
Compact transmission chain technology	Stand	Significantly improves the life of key parts in transmission chain
Compact transmission chain technology	Integrated gearbox	Longer life of the integrated main shaft
Overall damping	Rubber	Reduces fatigue loads on every part and extends their life
Status monitoring	Maintenance scheduling adapts according to actual conditions. Timely substitution is an effective failure prevention program	Extends the life of wind turbine and reduces maintenance cost

By using real-time status monitoring devices on the wind turbine, maintenance can be conducted according to the actual condition of the unit, which will contribute to increased revenue by reduction of maintenance costs:

Extends the operational and earning life of the unit
Reduces maintenance costs
Reduces the number of maintenance personnel
Reduces warehouse inventory for spare parts
Provides on-going reliable diagnostic information throughout the product lifecycle

Annual maintenance cost for 1MW unit saves approximately $10,000 - $20,000 USD compared to traditional systems.

Annual maintenance cost for 50MW saves approximately $500,000 - $800,000 USD compared to traditional systems.

Proprietary Monitoring Technology

Competitive Advantage Low Installation Cost

Two bladed installations are faster, simpler, lower risk and safer
On-ground assembly mitigates risk and overall difficulty
Fewer crane picks (3 vs. 5) simplifies scheduling
Use of cheaper 400 T Hydraulic truck-crane - arrives onsite and sets up faster. Remote rural region non-hydraulic lift system under development.
Lower transportation costs because of fewer trailer loads (4 versus 6)
Installation cost ~ 50% of that for 3-bladed turbines

GC China Turbine Corp. do not require a main bearing, pitch bearing and other key parts that suffer from constant global supply shortages
