If your new car
drove as much
as a wind
turbine,
it would have to
be scrapped
after
6 months*.
‘) The average car is scrapped after 4500
hours of operation. This equals 6 months
Operation of a wind turbine (www.dkwind.dk).
A Challenging Environment
Wind Industry’s
Service and Operational Risks
 Turbine performance during optimum
conditions
 Performance management expertise
 Budgeting for unplanned maintenance
events
 Spare parts access & availability and
supply chain reliability
 Shortages in skilled workforce
 Safe and environmentally friendly

Powerful match
Site optimisation is combining actual production data with historical mesoscale data
• Vestas PowerPlus™ wind power
plant optimisation is climate
dependent
• Actual production data with onsite measurements is used with
mesoscale data for increased
accuracy
• The result is the best possible
understanding of the climatic
reality on site

Data drives decision-making
Vestas is evaluating loads and AEP potential turbine by turbine – down to the component
level
• Upgrade-specific load
models ensure that
optimisation is done in
compliance with the
original design loads
envelope
• Load exceedances are
highlighted and mitigated
• Vestas uses a proprietary,
DNV-certified tool –
Vestas Site Check!

Optimised performance of wind turbines and increased annual energy production
Vestas PowerPlus™ is the newly
launched platform for production
improvement solutions
developed by Vestas and
dedicated to the aftermarket.
Up to
5
% Increased annual
energy production*
It currently consists of the

 Power Uprate
 Extended Cut Out
 Aerodynamic Upgrades
Site-specific optimization of
control parameters and
aerodynamic performance
Beyond that, Vestas
PowerPlus™ is a mindset within
the organization. It embodies our
commitment to constantly
improve our existing turbines.
Building on extensive wind
turbine knowledge and
industry-leading R&D
IWPC 2015-Istanbul- April 2015
*Actual AEP increase depends on turbine type and site conditions
Power Uprate
Increase production by fully utilising available load margins

Increase annual energy
production by up to 4%

Increase nominal power of V821.65MW to 1.8MW and V90/1001.8MW up to 2.0MW

Optimise use of available load
margins within certified design
loads envelope

Use Wind Sector Management for
optimal performance on
climatically challenging sites

Turbine- and site-specific loads
and AEP analysis performed by
Vestas

Optimise energy production on
interconnect grid limited site
using PPC to manage output

Combine Power Uprate with
Aerodynamic Upgrades (V82, V90,
V100) and Extended Cut Out
(V100)
IWPC 2015-Istanbul- April 2015
Model Power Curve of up-rated V90-1.8/2.0MW

*Actual AEP increase depends on turbine type and site
conditions
Extended Cut Out
Capture the full potential of strong winds by optimising cut out and re-cut in settings

Increase annual energy production
by up to 2%*

Extend cut out and re-cut in wind
speeds of V100 up to 25m/s and
V90-3MW up to 30m/s

Optimise use of available load
margins within certified design loads
envelope

Turbine- and site-specific loads and
AEP analysis performed by Vestas

Reduce abrupt stops due to high
wind, minimizing stress on drivetrain
parts

No increase in name-plate rating –
full benefit even on interconnect grid
limited sites

Combine Extended Cut Out with
Power Uprate on V100, and
Aerodynamic Upgrades on V90 and
V100 turbines
