The Benefits of Owning a Proven Wind Power System
Proven Energy turbines are robust, reliable and elegant producing energy under the harshest of conditions. The patented Proven Flexible Blade System enables the wind turbine to generate power in light or strong winds. We produce a number of wind turbines, each designed to offer sustainable energy solutions across a wide range of industry sectors, from domestic to offshore.
Proven Energy has many years’ experience and can help you choose the right system for your needs. We offer a complete service, from site assessment and system design to supply, installation and maintenance.
Robust
Proven Energy provides the world’s only robust, low maintenance turbine. We work closely with clients in a number of key market sectors to make sure their specific electricity generation needs are met.
Proven Energy’s internationally patented turbine has undergone extensive testing under the most rigorous of climate conditions. Our market-leading installations operate successfully throughout the world, from Antarctica to Saudi Arabia.
Unlike upwind turbines, the system works with nature and not against it. It lets you get the most out of any wind speed, helping to maximize your investment.

Design
The patented Proven Flexible Blade System enables the turbine to generate power in light or strong winds. This unique system, a combination of innovative design and the latest techniques in advanced composite technology, allows the blades to bend and flex.
As the wind gets stronger, the blades twist to reduce their aerodynamic efficiency. This lets the Proven Energy turbine maintain a high output even in the fiercest storms, unlike many turbines which need to stop generating power to protect themselves at high wind speeds. The blades also regulate their speed, preventing damage if the load from the turbine is disconnected through a power cut or electrical fault.
Low Noise
A Proven Energy turbine is designed to minimise noise and maintenance. It has a direct drive generator, which operates without a gearbox. The generator load is continuously monitored to keep the blades rotating at a low speed, whilst optimizing power output.
Compared with other modern small turbines, the blade tip speed of a Proven Energy turbine is low. This means that noise is reduced substantially. All that can be heard is the swish of blades turning in the wind, which is virtually unnoticeable.
Proven Energy controllers are designed to run the system automatically and display power output from the turbine. The power connectors and turbine brake are easily accessible at the base of the mast.
There is no need for specialist skills. On installation you will receive an easy-to-follow user guide, which gives you all the information you need. We recommend regular maintenance checks for optimum performance.
