The wind is one
of the cleanest sources of power. Wind turbines harness the power of the wind
to generate electricity. Wind tower is the support structure for a wind turbine
and its other components such as blades, turn around a rotor and create
electricity. It helps the wind turbine
blades to safely clear the ground and elevate the turbine to an optimal height
to generate electrical energy from the wind. The global
wind tower market size is expected to reach more than USD 26 Billion by
2023 with a CAGR of 7.45%. As the speed increases with altitude, it is better
to install tall wind towers to produce maximum output. Taller towers are
desirable because winds are stronger at higher altitudes, thereby producing
more power for each turbine installed. The opportunity to achieve 12% more
power output per installed-turbine could not be realized without addressing the
key height issues of installing 80m or higher towers.
MRFR analysts
have predicted that wind energy industry is about to grow at a rapid pace.
Moreover, the economic growth with emissions reduction have given the growth, a
momentum. Wind energy started with 40m to 50m towers that supported 400-kW to
660-kW turbines. These structures were mostly a truss tower type and can still
be seen in certain "wind farm cradles. The towers with capacity range of
1.0-MW and 1.5-MW, became tubular steel structures and foundation design
solutions were needed to solve the ever-growing load demand on the structure.
These tubular steel structures have become the mainstay of the wind tower
market.
Initial research
showed that, while a composite tower would reduce weight, it would not be able
to achieve the required stiffness levels and thus would be subject to
unacceptable resonance oscillation forces. The company applied its learning and
adapted the composite design to a highly innovative steel space frame structure
that achieved all of the design objectives.
Several tower
designs have been proposed for 100m and more. Conventional 80 to 100m towers
could be placed atop the 31m tall concrete foundation for hub heights 111 to
131m. The wider than conventional base also allows using less concrete and
rebar in the foundation.
Global wind tower
market is expected to be very broad in the coming years.
Leading Players
The key players
of global wind tower market are Suzlon Energy Limited (India), Enercon GmbH
(Germany), CS Wind Corporation (South Korea), General Electric (U.S.), Siemens
AG (Germany), Trinity Structural Towers, Inc. (U.S.) , Vestas Wind Systems A/S
(Denmark), Valmont Industries, Inc. (U.S.),
Ambau (Germany), and Broadwind Energy (U.S.)
North-America region is expected to grow
at the highest CAGR.
The wind tower market in the Europe region is currently leading, and is
followed by North America and Asia Pacific market. However, North America is
expected to grow at the highest CAGR, owing to the approval of various wind
tower farm projects in countries such as U.S. and Canada. This is because there
has been substantial investment into non-conventional electricity generation.
These factors will drive the market for wind tower market in North America
during the forecast period.
European governments and the EU, as a whole, have supported wind projects
with favourable incentives, as part of their carbon emission reduction goals.
The United Kingdom heads the field, with 46% of global installed capacity, in
2015, followed by Germany (30%) and Denmark (11.5%). Europe is currently the
leading region in wind tower market, and is followed by North America.
