What's your take on these notions?

IT'S TRUE!

Turbine reliability is a key factor that contributes to LCoE

A highly reliable pitch system design reduces maintenance requirements, improves turbine availability and maximizes power generating capabilities — all of which are critical to decreasing wind turbine’s LCoE.

TRUE OR FALSE?

"Pitch systems are costly and can't impact turbine failure rate"

TRUE OR FALSE?

"Changing pitch design can reduce unscheduled service by 50%"

TRUE OR FALSE?

"Turbine Reliability is a key factor that contributes to LCoE"

Click to find out

IT'S FALSE!

FACT: Pitch systems represent <3% of wind turbine CapEx, but their failures account for >20% of all wind turbine downtime

Pitch System is a major failure component. But by reducing part count, complexity and optimizing design architecture, reliability can be increased and OPEX associated with turbines can be reduced.

IT'S TRUE!

Unscheduled service requirements can reduce by up to 50%, by just changing pitch design

With increased reliability, advanced pitch system design drastically reduces maintenance requirements. Its compact, lightweight and modular design also allows for easier handling of components, which improves the safety and efficiency of O&M activities.
