Frequently asked questions

The cost of electric generating systems is always expressed per kW of power. Turbulent prices for a full system including civil works are estimated to be between 2500-4000 Euro/kW.
Note: Price per kW decreases when higher kW Turbine power. Civil works cost variate according to location and local contractors.’

Please have a look at our easy hydropower manual. If you have these values, you can easily compare them with our product range to see if it is possible. https://drive.google.com/open?id=1BgRMseFfqKFMiLEAAMY6tSYutQTpf4il

Sorry but this is not possible. It goes against the laws of physics and is called A perpetuum mobile.

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 remain 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.

We do not yet natively integrate energy storage in our system. If desired, a home backup battery system can be installed.

Yes, you can use a hydro turbine together with solar panels or wind turbines without much trouble. Depending on the installed power, we might have to request your distributor to reinforce your connection to support the additional energy.

Yes, our turbines can be fitted for off-grid usage.

This depends on your country’s standards. Generally, up to5 kW can be installed with a single phase connection. Above this power, it is usually obligatory to use a three phase connection. In most locations, single phase connections can be changed into three phase connections quite easily.

We can fit our turbines to work with any electricity distribution standard in your country. Our operating voltages range from 200V to 480V and both 50Hz and 60Hz systems are supported.

No dam, means no flood risk related to the installation. Your stream will behave in the same way, as if untouched. structure unchanged

No, this is one of the key features of our technology. Water circulates for a few seconds in the plant before moving downstream. Therefore, no impact at all on your flow or the flow of your neighbors.

The efficiency is 60% and the limit of cabling is around 1 km for a 15kW, because of the cost of cabling. For larger projects, we can provide a transformer to go through higher voltages which allow longer distances of up to 30 kilometers.

There’s normally more water during winter, and for those places where the temperature is freezing, our turbines are adapted with special components to shake off the ice. We can’t store water – that’s the goal of the vortex turbine. Water stays in it for a few seconds and thus it does not affect the river.

We designed this turbine to be debris tolerant. It is a slow turning turbine with a huge spacing between the blades. Our rotor is designed with a pressure wave before it that pushes dirt, plastics, and other debris through the turbine.

Yes. Our turbine is fixed pitch, but virtually modifies the pitch with the MPPT algorithm and speed control. This changes the RPM so it looks as if the blade pitch is changed. It has to do with relative velocities.

Sure, here is our brochure.https://drive.google.com/open?id=1VRUtlCzJNGdC7gDl5pmqZiEz9jPY-xox

All the systems to make the turbine operational such as generator, cabling, turbine core unit are included.

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 10 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 self-cleaning rack, big debris is kept out while small debris is simply taken in the vortex and washed away. The low turning velocity also increases the lifespan of all parts.

Between 2 to 4 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 weeks, the installation of the core unit including commissioning will take 1 to 3 days.

We will send to you the core unit which is capable of commissioning itself. You only need to take care of a proper installation for which we will provide you with a manual.

The advantage of hydropower is it runs 24h a day, 7 days a week. If you want to calculate your revenue, take the amount of power you can install, multiply it by 7500 and your electricity price, and you get your revenue.

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 can produce energy constantly, day and night. Therefore, the price per kWh with our technology is way lower than any other source and much more reliable!

We develop our turbines specifically for ultra-low head 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 (can be carried by 4 people when it’s in modular segments) and local entrepreneurs can do the maintenance and repairs.

All other small hydropower technologies still rely on specialty components and special concrete structures. That way they always need a specialist (read German engineer flying over) to install and repair. A few companies also started using a Rankine vortex for energy production (Zotloeterer an Kouris), 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.

Desde sus inicios diseñamos la turbina para ser resistente a los escombros. Tenemos un gran espacio entre los álabes. Además la supericie de éstas que tiene contacto con el agua está diseñada para dejar que los escombros resbalen.

The efficiency is 60% and the limit of cabling is around 1 km, because of the cost of cabling. Most of the time the distance is also limited in Belgium because of regulation. No public roads can be crossed.

Yes, you can use a hydro turbine together with solar panels or wind turbines without much trouble. Depending on the installed power, we might have to request your distributor to reinforce your connection to support the additional energy.

Yes, our turbines can be fitted for off-grid usage. We recommend however to opt for a mains connected system. That way, your excess energy is sold, leading to a faster return on your investment.

We can fit our turbines to work with any electricity distribution standard in your country. Our operating voltages range from 200V to 480V and both 50Hz and 60Hz systems are supported.

Our maintenance work is very low and punctual. Thanks to a self cleaning rack, big debris is kept out while small debris is simply taken in the vortex and washed away. The low turning velocity also increases the lifespan of all parts. And yes, we take care of the maintenance.

No dam, means no flood risk related to the installation. Your stream will behave in the same way, as before the installation.

The cost of electric generating systems is always expressed per kW of power. Turbulent costs EUR4000/kW for the core unit excluding works. When the civilworks are done by a local contractor the price will go up to EUR4300 to EUR4600/kW.

Most renewable energy sources face problems of profitability and rely on government grants. Solar and wind deliver an intermittent power to the grid, causing a plethora of grid instabilities. Hydropower doesn’t have these problems, but large hydropower, with dams, causes other ecological side-effects such as flooding, desertification, people migration, increase of methane emission, etc. A form of decentralized green energy production with standard materials and easy installation can be used to offer a solution for off- and on-grid locations.
