Wind Turbines
Economics
- 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 |
| 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:
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.
- 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 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
- 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
