Help us to improve the monitoring of wind farms

Iberdrola group has launched a new Startup Challenge in search of solutions that will help improve monitoring systems on wind farms, especially those solutions that can be implemented quickly, easily and inexpensively on older farms.


Iberdrola is committed to clean and renewable energies in order to move towards a sustainable, safe and competitive energy model, focusing on wind energy as one of the best-positioned technologies to deal with this energy transition. Today, the group is the world leader in renewable energies and the leading wind power producer, with an installed capacity of more than 18 GW in onshore wind and more than 1,200 MW in offshore wind.

Part of the company's commitment to the development of wind energy lies in the constant search for greater efficiency and the reduction of operating and maintenance costs to increase competitiveness. In this sense, monitoring systems for wind turbines and the associated electrical infrastructure are a key element in extending the life of the wind farms. These systems collect data that allow diagnostic and prognostic models to be developed, making it possible for maintenance to be not just corrective or planned, but rather based on the condition and early fault detection.

One fundamental element is the sensors and monitoring solutions that measure different parameters associated with the turbine components, which feed the control and alert system of the wind turbine and the diagnostic systems. Iberdrola's new Startup Challenge, once again part of its PERSEO - International Startup Program, aims to find solutions to improve these sensors and systems.


The challenge is to find innovative and competitive wind turbine monitoring solutions that meet the following requirements:

 They are low cost solutions or sensors.

 They are low-powered or self-powered.

 They can be implemented in wind farms already in operation with turbines from different suppliers. Special consideration will be given to the speed of installation and to making as few modifications as possible to the existing hardware.

 They have few wiring requirements (power/communications). Wireless and autonomous sensors — that do not need external power — will be appreciated.

 They use long-distance wireless data transmission protocols (such as LoraWAN), which enable centralised data collection at the substation or the operations and maintenance base.

 They have On-edge data processing to reduce the bandwidth needed to transmit the data.

 They have open interfaces for the post-processing and sending of the raw data.

 They are multifunctional sensors and combine, for instance, temperature, pressure, humidity and triaxial vibration data.

Proposals are included in one or more of the following categories:

 Innovative sensors and systems for monitoring the components of the drive train (main bearing and gearbox). In this category, vibration sensors, main shaft torque measurement sensors, accelerometers — including those that can go inside planetary gear trains in gearbox — will be considered.

 Low-cost wireless sensors for measuring the temperature of rotor bearings.

 Wireless sensors for measuring gear tooth wear, etc.

 Wireless acoustic sensors and innovative monitoring systems for monitoring the breakage of components inside the rotor.

 Low-cost wireless sensors for monitoring the structural behaviour of foundations, by capturing tilt, tension and low-frequency vibration (<100 Hz).

Deadline for
of the winner


 The prize will consist of us signing a collaboration and testing agreement with PERSEO and/or with any other Iberdrola group company. PERSEO or the signatory company will assume the costs of these activities and will provide the winner with the necessary technical support, as well as a real environment and data to test the solution, giving them access to equipment, infrastructure, high-tech sites and joint work areas.

 If the trial or concept testing is satisfactory, Iberdrola could offer the participant the chance to scale up the solution by adopting it through commercial agreements.

 PERSEO may also consider investing in the participating company and/or in the winning solution.
