Within the next years more than 80% of the wind turbines in North America will be operating past the expiration of the manufacturer’s warranty. This means these turbines be maintained under a series of mainentence contracts. The companies responsible for the now aging fleet of wind turbines are wholly responsible for their performance and profitability. A physically small but critically important component on a wind turbine is its wind sensor. The wind sensor, or anemometer is installed atop the turbine’s nacelle and directs the controls to yaw the turbine into the wind for optimal performance.

Wind Turbine Fleet in the US Today
• In
2011,
nearly
$40
billion
worth
of
wind
installa5ons
in
the
U.S.
came
out
of
warranty,
thrus5ng
the
financial
risk
on
the
owner
to
provide
cost-­‐effec5ve
opera5on
and
maintenance.
• In
the
next
20
years,
the
U.S.
will
require
more
than
100,000
addi5onal
wind
turbines
to
supply
20%
of
the
na5on’s
electricity.
• For
exis5ng
turbines
cost
effec5ve
replacement
of
turbine
parts
is
a
necessity.
More
energy
demand
required
from
an
aging
turbine
fleet.
Qualified
maintenance
services
can
cost
$100’s
an
hour!
• Project
owners
need
to
find
ways
to
reduce
costs
and
increase
reliability
of

The

help
with
this!

• Every
large
turbine
requires
a
wind
sensor
on

of
the
Nacelle
in
order
to
operate
• Tradi5onal
wind
sensors
require
regular

which
is
a

cost.
• Tradi5onal
wind
sensors
fail
due
to

or
physical

to

• Sensor
replacement
is
dangerous
