Predictive Technologies of AQTech Generate Savings of R$ 35 Million in Energy Operations
AQTech, a leader in monitoring and diagnostic solutions for the electric power generation sector, achieved significant savings of R$ 35 million through the use of predictive technologies in wind turbines in Brazil. The recent report highlights the impact of such technologies on approximately 200 wind turbines, monitored in real-time by the Condition Analysis Center (CAC), which identified more than 270 incidents in 2023 alone.
Advancements in Monitoring and Diagnosis of Wind Turbines
Located in Florianópolis, one of Brazil’s main technological hubs, AQTech’s CAC specializes in the treatment and analysis of remotely collected data. Operating since December 2021, this center is entirely dedicated to monitoring the operational condition and maintenance of energy assets, such as wind and hydroelectric turbines. Currently, AQTech manages over 16GW of installed power in real-time.
In 2023, the CAC produced approximately 300 monthly reports and recorded 271 incident diagnoses, revealing issues mainly in critical components such as the gearboxes of wind turbines. These diagnoses are crucial to prevent risks of unavailability and prolonged energy generation losses.

Cost Reduction and Increased Operational Efficiency
Emerson Ancini, AQTech’s sales director, attributes the R$ 35 million savings to the ability of the company’s predictive technologies to identify adverse conditions in turbine components, signaling the need for preventive maintenance and component replacement at the most opportune time. “These monitoring and diagnostic systems are essential to reduce failures and unplanned shutdowns, which, in a competitive market like energy, can make the difference between significant profit and loss,” highlights Ancini.
Monitoring through cameras and sensors allows not only the detection of early-stage failures but also optimizes maintenance logistics, reducing the need for labor in hard-to-reach locations and extending the useful life of equipment. This process not only saves resources but also ensures safer and more reliable operations.
Certification and Innovation in the CAC
The team at the Condition Analysis Center consists of engineers, data scientists, and vibration analysts, all certified by ISO 18436-2, a standard that recognizes professionals of excellence in machine analysis and evaluation. In addition to monitoring operational conditions, the CAC issues continuous reports on necessary repairs and emergency actions.
“Daily monitoring of the systems allows us to identify small deviations in the condition of the assets and associate these deviations with specific defects. This gives us enough time to plan interventions that maximize the lifespan of the components,” explains Emerson Lima, manager of the CAC.
Forecasting for the Future and International Expansion
With plans for expansion and internationalization from 2024 to 2027, AQTech aims to increase the number of monitored turbines and structure the support and training of international partners. The company is also in the process of becoming a certifying institution for the training of professionals in the sector, further expanding its impact and presence in the global energy market.
The application of artificial intelligence in monitoring and diagnostic systems is proving to be not only a valuable tool for preventing failures but also an effective strategy for generating significant savings, highlighting AQTech as a pioneer in innovative solutions for the energy sector.
