 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

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
