New research on blade tip improvements
2020 - present
In cooperation with
GE Renewable Energy & LM Wind Power
A consortium of TNO, GE Renewable Energy and LM Wind Power are collaborating on the TIADE project to develop technologies and design methods for more efficient operation of next-generation wind turbine rotors, wind farms with large rotor wakes and demonstrate them in the field.
The TIADE project touched a new milestone with the research wind turbine becoming fully operational. The innovations developed in the project will be tested on the full-scale 130 m diameter turbine recently installed in Wieringermeer, Netherlands. The turbine is powered by two-piece blades, which allows the outer 12 m of the blades to be replaced by several innovative tips.
"Innovations in wind turbine blades are essential to make renewable wind energy even more affordable." Peter Eecen, R&D Manager at TNO Wind Energy.
We are proud we will validate blade innovations and aerodynamic simulations tools in the field, together with GE Renewable Energy and LM Wind Power. Thereto advanced measurement techniques are used in a unique set-up that combines detailed wind inflow measurements and unsteady pressure measurements on the blade." Peter Eecen, R&D Manager at TNO Wind Energy.
"Our revolutionary two-piece blade design has helped us drive down the levelized cost of energy. Here, in this project, we are applying new technology to significantly increase speed and reduce cost associated with testing and validation," said Ben Hendriks, Chief Engineer Turbine System Integration at LM Wind Power.
Innovative add-ons on wind turbine blades
Various innovative blade add-ons, such as spoilers, serrations, vortex generators, ‘turbulators’ and blade tip improvements will be validated using advanced measurement techniques. The results will accelerate widescale application of rotors with higher annual energy production and thus a considerably lower cost of offshore wind energy.
These solutions can be applied to newly manufactured wind turbines in the factory, but they can partly also be retrofitted to existing offshore wind farms. With both options available, implementation of the technologies in offshore wind farms can be done from 2023.
The consortium comprising of TNO, GE Renewable Energy and LM Wind Power was established in 2020 to test new research on blade tip improvements under the three-year and ten months TIADE project, with partial funding from the ‘Topsector Energiesubsidie’ of the Dutch Ministry of Economic Affairs.
Peter Eecen is R&D manager at TNO Wind Energy and is responsible for the research strategy on offshore wind energy for a group of about 55 researchers. As R&D manager Peter is to shape the R&D programme such that products are developed and – together with colleagues and collaborators – are brought to the market. As such, Peter is responsible for the commitment of the TNO research funding, the acquisition of projects in national programmes and in European programmes. Peter is coordinator of the EERA Joint Programme on Wind Energy.

Designing sustainable wind turbines for the circular economy
At the end of their life wind turbine blades end up as landfill. TNO is working on the design of turbine blades that can be recycled.
Offshore wind conditions
For the development of wind farms at sea, developers need knowledge of the wind conditions. TNO knows the wind conditions through wind measurements.
Efficient operation and maintenance of offshore wind turbines
Maintenance of offshore wind turbines accounts for a quarter of the total costs. TNO has been researching ways to maximise maintenance efficiency.
Innovations for the large wind turbines of the future
New generations of wind turbines are following one another in rapid succession. Together with partners, we are working on design of new generations of wind turbines.
How large offshore wind farms produce optimal energy
Optimising the performance of wind turbines in offshore wind farms is becoming complex. TNO is working on optimal wind farm design.
