1. Overall investment cost is still too high- Custom engineering adding on to the total cost- Complex BOP components further increase cost- Foundations in uncooperative soils can drive the cost up- Transport & installation often overlooked and exorbitant
2. Reliability still an issue - Wind turbines do need maintenance- Lack of ownership, especially in less developed regions
3. Yield at low-windspeed sites could be better- Turbines are installed close to load centres- We need low-windspeed rotors that can cope with extreme conditions

CONCLUSIONS
International Wind-Diesel Conference |
20
Bring the project cost down by reducing the cost of engineering: “a few sizes fits all” by reducing the cost of transport & installation by reducing the cost of BOP components
Expand the market beyond these niche markets of industrialised regions with high COE to the developing world
We need very reliable turbines that require minimal maintenance
We need turbines optimised for low wind-speed sites that can cope with extreme conditions
