Market is quickly moving away from the older blades associated with 1.5Mw IEC 1 technology

There is an expectation that older 40-49m technology (1.5-2.0Mw) in China and India will transition to 50m technology

Evolution of the 2-3Mw turbines will drive growth of the 50-59m blades

As offshore technology develops (Europe) it will drive growth of 60-69.9m segment

>70m segment will be driven by majors such as Siemens, LM as turbines exceed 6Mw

Producers are finding that delivering the potential of carbon in blades is challenging and recent innovation in high modulus glass offering reduced tooling, less handling issues and significantly lower total material costs

WINDSTRAND® PRODUCTS REDEFINING OUR PLATFORM TO MEET EMERGING INDUSTRY NEEDS

1994 to early 2000s

ON-SHORE Turbine sizes increase to utilize available wind at on-shore locations requiring cost effective material solutions to enable scaling of the industry across regions

LIMTED OFF-SHORE Offshore production started in early 2000s with small number of blades of around 50m+

Present

ON-SHORE (LOW WIND) Expansion of the industry means turbines are now positioned in low wind areas requiring longer, lighter high performance blades to generate economic electricity

OFF-SHORE Drive to production of high performance blades, capable of operating in extreme environments (75m in glass and 80m in carbon) and driving turbines of up to 8Mw to reduce cost of energy.

The huge investment cost demands ultimate reliability of operation to ensure cost effective operation

ON-SHORE (HIGH WIND) Continued pressure to reduce capital/operating cost of turbines to make electricity more competitive requiring optimization to enable reduction in material consumption, manufacturing and operating costs
