The AOC 15/50 wind turbine is the evolution of the rugged and reliable Enertech E44, hundreds of which were installed in the 1980’s and are still running today. Independent analysis and testing at the National Renewable Energy Lab (NREL), the Netherlands Energy Research Foundation (ECN), RISO Laboratory in Denmark, the Atlantic Wind Test Site (AWTS) on Prince Edward Island and other sites around the world verifies our wind turbine generators high availability in even the harshest weather conditions.


SPECIFICATIONS OF THE AOC 15/50

Hub Height - 25m

Rotor Diameter - 15m

Cut In Wind Speed - @hub height 25 m (82 ft) cut - in 4.6 m/s (10.2 mph)

Shut Down (high wind)- 22.4m/s (50 mph)

Peak (survival) - 59.5m/s (133mph)


Absolute simplicity with
minimal maintenance requirements: 

  • PLC based control system

  • Four independent braking systems: 
    - tip brakes
    - dynamic brake
    - parking brake
    - and stall regulated blades

  • Downwind passive yaw configuration

  • Glass-fibre  high efficiency blades 

  • Produces 3phase, 480VAC power

  • Machining and assembly of drivetrain ISO 9001certified.
One of the most important safety criteria in the design of the AOC 15/50 is the ability to safely control the wind turbine in normal and extreme conditions. This has led to the development of redundant failsafe control mechanisms. The ultimate goal above and beyond low cost and high reliability is the protection and safe operation of the wind turbine in all specified conditions.
