Improving the reliability of renewable energy

Wind turbine icing results in significant power and revenue loss for wind farms. Our patent pending device is an internal blade heating retrofit which is installed inside the rotor blades. It is easy to install: no cranes or rope access required. The device is able to de-ice the rotor blades in under 90 minutes at -5°C (1).
Our system can be installed in two days with only three technicians(2) and operates once the wind turbine has shut down due to rotor blade icing. The de-icing system then circulates warm air within the blade to target the critical area, the tip of the blade.  It has been designed as a retrofit for rotor blades. The de-icing system is customizable to various wind turbine models.
We have done extensive simulations and are in process of field verification. Using the simulations, we confirmed the functionality of the design, and determined that the de-icing process will only take 90 minutes at -5°C and reduce down time by at least 80%(1). We are currently conducting physical tests. We will collect in-turbine data this winter.


Return on Investment

Our return on investment calculation is based on reclaimed power. Our system will reclaim at least 80% of the revenue lost to icing(1). Even if a 2 MW wind turbine were to have only 1 week of icing each winter, that means a payback period of 3 years(3). We are currently offering our system at a reduced cost for our early adopters.

Our device will pay off in only 3 weeks of icing downtime(3)

Risk & Warranty

We are working with wind turbine manufacturers to ensure that the installation procedure and systems are safe for the technicians and then wind turbine. All components that will be installed in the blade are CSA approved and rated for operating in an environment such as the interior of a wind turbine blade. We are conducting extensive physical tests and we will be installing sensors on all critical points inside the blade to ensure the safety of the wind turbine.


We have a unique opportunity for wind farms with the GE 1.5/1.6 MW wind turbines.
