Proven Energy turbines are robust, reliable and elegant producing energy under the harshest of conditions.
Our 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 off-shore.
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.
For more information, Take the Tour or Find a Turbine.
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 maximise your investment.
DESIGN
The patented Proven Flexible Blade System enables the turbine to generate power in light or strong winds. The 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 optimising 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. But don’t just take our word for it - Find a Turbine and arrange a visit to an existing turbine near you.
Low Maintenance
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. These can be carried out by a local distributor.
The Proven 2.5 produces 2.5kW of electricity. This can meet the power needs of a standard three-bedroom home, excluding heating. Any excess energy production can be stored or exported to the grid, depending on local regulations. The turbine is approximately the same size as a standard telegraph pole.
The robust Proven 2.5 can be used to power small lighting systems in commercial premises. The Proven 2.5EX is widely used on off-shore oil platforms, as it is the only turbine in the world that is totally explosion-proof.
Grants and funding for installation are widely available for consumers and businesses. Generating electricity from a wind turbine helps to cut down CO2 emissions and reduces climate change levy charges. See our Funding page for further information.

All Proven Energy turbines are available in three standard systems, which manage the use of the electricity generated.
1) Grid Connection
Electricity is fed directly into your fuse box or distribution board, providing power to your premises. Any surplus electricity produced may be exported to the grid and sold to an electricity provider, depending on local regulations. Convenience and the opportunity to sell excess electricity have made this the most popular option. For more information on local regulations, contact us, fill in a few details and a local reseller will be in touch to answer your queries.
2) Battery Charging
Energy produced by the turbine is stored in a large battery to provide a power supply. This is most beneficial in remote locations which are not connected to the grid, or which rely on a diesel / oil generator. Installing a turbine can reduce fuel consumption by up to 95% and payback for such sites can be almost immediate. There is also a positive environmental impact when fossil fuel is not used for power generation.
3) Direct Heating
Energy produced by the turbine is directed to hot water tanks, storage heaters or under-floor heating, rather than providing electricity to feed into your power supply.
Whether you are interested in reducing domestic electricity bills, powering a telecom mast on the top of a hill or generating green electricity to power your business Proven Energy can work with you to find a sustainable energy solution that fits your needs.

Wind Energy is the world's fastest growing renewable energy sector, with more and more people successfully making use of wind power in their homes and businesses.
Wind energy is a form of solar energy - as long as the sun shines, the wind blows! Sunlight falls on oceans and continents, causing air to warm and rise. This in turn generates surface winds which spin the turbine blades to produce electricity.
By choosing wind energy, you:
- Help the environment - wind turbines produce no air pollution
- Reduce energy dependence on the grid
- Reduce costs
- Allow for remote electricity generation.
Proven Energy wind turbines are robust, reliable, elegant and efficient and can help you maximise your investment.
Financial benefits of wind energy
Your green energy choice can make excellent financial sense, depending on your wind resource:
- A small wind energy system can lower your electricity bill by 50%-100%
- Set up costs for off-grid power are minimised
- Expenditure on fossil fuels is reduced
- You can turn an under-utilised location or resource into a source of energy generation and revenue.
Wind energy systems can help customers reduce the amount of electricity purchased from their utility provider. They can also cut down dependence on fossil fuels, and they are non-polluting.
Over its life, a small residential turbine can offset approximately 1.2 tons of air pollutants and 200 tons of greenhouse gases.
