PowerCone retrofit reduces peak loads by up to 10% while improving cut-in and power performance.
PowerCone is a turbine retrofit used to increase clean energy output from existing wind turbines, manufactured by a Canadian firm called Biome Renewables.
Biome Renewables is responsible for implementing and distributing since the product is still a prototype. Networking partner is CanadaCleantech. They help in scaling-up technology and providing exposure.
There is a strong and competitive market for wind turbines with about five listed on the solution library of engineering for change. These include the Breezergy Micro Wind Turbine, the Marlec Rutland 913 Windcharger, Kite Power Solutions (KPS) and other Micro Wind Turbines available on the market.
The product is useful to existing wind turbine installations.
Additive manufacturing was used to manufacture the parts from glass fiber composite material. Inspired by the kingfisher and the maple seed, the manufacturer applied fluid dynamic principles and a re-thinking of Betz’ Law to engineer the PowerCone. The product is at the prototype stage.
The first prototype was installed in summer of 2019 in Canada by the manufacturer and Carlsun.
The prototype will be installed at Capstone’s Skyway8 wind farm northeast of Toronto, in partnership with Carlsun.
Is it a turbine, kite, etc?
How tall is this system and/or how high above ground does it operate?
The radius of the system as it is turned by the wind
What type of controls are used, remote diagnostics, etc.
The following are design specifications the designers expected to achieve with the PowerCone:
- The impact of the PowerCone® when wind speeds are between 5-6 m/s could increase a turbine’s output by as much as 50%,
- Expected to reduce GHG emissions by 197.8 tons of CO2 (tCO2) per turbine. The net reduction would be 1000 tCO2 (5 turbines over a full year).
- Has a 53% peak aerodynamic efficiency
- 13% increase in annual energy production
- Reduced loads
- Generating less noise
Questions, enquiry are addressed by completing the enquiry form available at the product website. A technical brochure is available for download on Biome Renewables website.
It’s designed to be an enhancement device that can be fitted to 98% of installed wind turbine worldwide.
External organizations (Queens University Belfast and Cuan Marine Services) did the testing. 51% Peak aerodynamic efficiency with More than 6% increase to annual energy production and peak loads reduction by up to 10% were reported.
Biome Renewables partnered Queens University Belfast and Cuan Marine Services in testing the PowerCone in Strangford Loch, Northern Ireland. Other technical partners include DNV turbine engineering, Power factors, NREL, and leading research institutes and OEMs did the assessment.
Avoid maintenance or repairing actions when the turbine is rotating.
To prevent injury caused by electric shock, users are advised to handle the system with caution. Only trained personnel are permitted to maintain and operate it.

IEC 61400-1 standard specifications and is manufactured to ISO 9001:2015 standards to be OEM agnostic.
The manufacturer commissioned Glas Ocean Engineering, Alison Mark Consulting, Researchers from Dalhousie University and Queen’s University Belfast (QUB), to analyze the PowerCone as a tidal current turbine and investigated new materials for use in tidal turbines.
The retrofit is adaptable to tidal turbines
