General
Depending on several variables regarding the customer’s situation, such as the local energy prices, current energy solution, using expensive diesel and others, Turbulent offers projects with a return on investment between four to eight years.
In many cases, it can be less than six years.When our solution is being used to replace diesel generators in remote areas, the payback period can be as low as two years.
Regarding other renewable energy resources, such as solar energy, our hydropower technology has a competitive price to a solar plant with batteries.
A Turbulent hydropower turbine is an investment. An investment in yourself, your company, in your future, in short, in a better world. Our projects supply enough energy to respectively power between 33 and 440 households*. In a remote community, these numbers can add to 185 to 2000 households**.
In addition, our sustainable and eco-friendly technology will withstand severe weather conditions, such as floodings, which means no extra repair costs due to external factors.
*Based on a 4000 kWh average yearly energy consumption, for an on-grid project.
**Based on a 700 kWh average yearly energy consumption, for an off-grid project.
Due to grid regulations, the generator must disconnect when there is a power outage. This is to protect workers. Although it is not impossible to continue generating energy during a power outage, we do not provide this feature by default yet. We are available to look for the custom solution you need.
For those places where the temperature is freezing, our turbines will keep working as long as the water flows. Our turbines are adapted with thick rubber coating that can shake off the ice (similar to the turbine cones of Boeing but made specially for low rpm). Once the river is frozen, the turbine will stop. No damage will happen to the turbine because of freezing temperatures.
The Turbulent turbine units are scalable in size to 70kW. By increasing our 15kW to a 70kW, the increase in power follows a continuous growth. By installing more Turbulent turbines in parallel and series along the length of the river you can increase the power output and reach MW projects that can power entire cities. The benefit is that you can cascade the turbines and produce the energy close to communities to limit distribution losses. Our decentralized approach also allows you to use standard series-produced turbines that are being manufactured at a lower cost.
The warranty is for 1 year by which time all possible defects will be shown. After this first year, your main cost will be maintenance and planned repairs, as quantified under our operational expenditures. The rotor itself can last 5 years and the generator is rated for 15 years. All in all, the large structure such as the basin can last for up to 50 years.
Our maintenance work is very low. Thanks to a protective trash rack for large debris, small debris can safely pass and therefore minimize the risk of blockage. The low turning velocity also increases the lifespan of all parts. Turbulent, or our local partner, takes care of the maintenance for you, according to the plan you choose.

Between 2 to 5 months after signing the contract and partial payment, we will have the core unit ready to ship. The building of the civil works will take on average 2 to 4 weeks, and the installation of the core unit including commissioning will take up to 2 weeks. This means in the best case, a project can be up and running in as little as 3 months.
This is actually a very smart way to use the excess energy that you are producing. Considering that our turbine is turning at a very low speed but with very high torque this makes it possible to power agricultural equipment as well as small industry machines without any problem. Our turbine is perfectly suited to do this because it is so easy to manufacture.
We develop our turbines specifically for ultra-low head sites with a low installation cost. Using the natural principle of the vortex creates a turbine that is subject to very low forces and that is fish friendly. This way we can use composites in our high unit volume production and can make the turbine light (it can be carried by 4 people when it’s in modular segments) and local entrepreneurs can do the maintenance and repairs.
Although we acknowledge our esteemed competition in their goal of creating sustainable hydropower, all current small hydropower technologies still rely on specialty components and special concrete structures. That way they always need a specialist (read: flying engineers in) to install and repair. A few companies also started using a Rankine vortex for energy production, but they couldn’t achieve a small size and high efficiency.
Most hydro power technology providers are focusing on the highest possible efficiency, but forget to design for robustness and a low maintenance design. All of these technologies require expert knowledge to maintain and repair them.
Turbulent vortex turbines are designed with our end-users in mind. They are simple to maintain, simple to repair and require no expert knowledge whatsoever, to keep them going.
This investment to start your micro power plant project guarantees an evaluation that will allow you to advance in your business and investment model. It gives you an answer to the question whether our technology is suitable for your site. You will receive the following services:
-A high level quote for your project: a range of price per kW of our turbines and services.
-Turbine sizing and energy production: with the head and flow information you provide us, we estimate the power potential and the number of turbines that can be installed on your site as well as energy estimation.
-A satellite inspection of your site and flow data from your stream (if available online).
-30 minutes of consultancy with our engineering team to discuss your project details
* If the project continues to step 4, which is the engineering feasibility study, the 750 euros that you invested will be deducted from your final invoice.
