Wind turbine manufacturing and service

An innovative system that allows the machines to achieve maximum energy efficiency and high performance.

Our experience in the wind energy sector dates back to the 80's when Riva Calzoni in Bologna, in collaboration with the German company MBB (Messerschmitt-Bolkow-Blohm), developed one of the first wind turbine generators in Italy. M30 was a single-blade turbine with a pitch control system which represented an innovative design at the time.

Since then, we have always maintained the interest and enthusiasm that led us, in 2012, to return into the wind business market with “under 1 MW wind turbines”, acquiring a share in S&G Engineering GmbH, a German company well-known for its wind turbine technology.

Our technical breakthrough is based on a unique hybrid concept which combines the advantages and simplicity of a robust German engineered gearbox with a high-speed synchronous permanent magnet generator, leading to an optimal generation output.

Our turbines have a state-of-the-art pitch control system, an oversized rotor to capture more energy even at low wind levels.

Wind Turbines

An innovative system that allows the machines to achieve maximum energy yield and high efficiency.

All ATB wind turbines have been designed according to IEC 61400. ATB wind turbines are built according to the concept of a variable speed synchronous generator with a full converter system and hydraulic pitch control. That concept is characterized by maximum energy yield and high efficiency. The sophisticated power converter concept permits powerful and rapid active and reactive power control, and thus creates the conditions to maintain network stability.

Bankable and Investment-Ready 

In a continuously changing market, the strength of covenant and the manufacturer's warranties and services have become key to finance wind energy projects.

ATB provides an end-to-end service in the manufacture, construction, operations and maintenance of ATB turbines, providing complete accountability and a high degree of reliability with its ATB Wind Service lifetime plan. Technical excellence and customer-oriented support put our products at the top of the sub-megawatt market.

High Efficiency 

Every ATB wind turbine is built to the highest standards of engineering, performance and quality. ATB has developed highly efficient wind turbine technology reaching the rated output power at lower wind speed than most available models and this resulted in ATB wind turbines be known as "“best-in-class” in the sector.

Advanced Pitch Control 

ATB wind pitch control system automatically and synchronously adjusts the pitch of each blade to optimize efficiency. The blade adjustment is made extremely quickly, reacting to changes in wind conditions within around 0.1 seconds.

Blade and Nacelle

Our advanced blade design contributes to optimize power generation. The technology also has an integrated slow speed shaft that reduces space constraints in the nacelle by avoiding main bearing and lengthier slow speed shaft.

Advanced Pitch Control

ATB Wind Turbines is equipped with a specialized cooling system that guarantees continuous and efficient operations under diverse climatic conditions. This feature is a must for varying temperature conditions across regions.

Reliability

Engineering excellence and exhaustive testing are the cornerstones of our wind turbine design, production and deployment process. Throughout initial design and subsequent revisions, all of our models are manufactured to ensure our customers can count on their turbines over a 20-year lifespan.

Remote Monitoring

The remote control allows users to remotely monitor the turbine’s operational status, live energy production, wind speed and power output.

The operating parameters data stored in the control unit of the wind turbine are constantly monitored and automatically adjusted during operation. The parameters are tuned to each site to ensure the safe and automatic operation of the wind turbine in all situations.

Safety

When the turbine control system detects any fault, such as high wind or a grid power loss, the pitch system activates, rotating the blades and safely stopping the turbine. In addition, a mechanical parking brake supports the aerodynamic brake and brings the rotor to a standstill until the condition is cleared.

Product applications

ATB Wind Turbines are well-suited for both On Grid & Off Grid applications such as:

  • Self-consumption
  • Net-metering
  • Community projects
  • Islands or remote areas
  • Hybrid renewable systems
