Affordable & Clean Energy Solutions

The clean energy industry generates hundreds of billions in economic activity and is expected to continue to grow rapidly in the coming years. There is tremendous economic opportunity for countries that invent, manufacture and export clean energy technologies.

In the journey towards sustainability, clean energy is also part of the key solutions provided by Renexus Group. Our solutions help nations harness the power of renewable energy resources in the form of hydropower, biomass and solar. Renexus plays an instrumental role in conserving nature by reducing the use of natural gas & coal in electricity generation and utilize the resources to produce renewable energy to the country.


Due to the intermittency of wind and solar production, hydropower is one of the most attractive and intriguing solutions to harness energy, yet there are not many types of viable technologies for low-head hydropower.

Introducing the most profitable low-head hydropower plant – Turbulent low-head vortex turbines. A reliable and continuous on- and off-grid alternative to diesel, solar, wind and other intermittent generators.

Renexus through its collaboration with Turbulent is bringing a new way to approach hydropower by harnessing energy from the natural flow of the stream, a design that separates itself from other low-head hydropower ideas in simplicity, reliability, and cost-efficiency.

Turbulent water turbines can help to save the planet by providing clean, reliable energy in a cost-effective way.

The simplicity and cost-efficiency of Turbulent micro-hydro water turbines open up a new world of opportunities to isolated rural communities, especially on the development.

Hydroelectric turbines for green, decentralized, off-grid living.

We develop cost-effective hydropower plants that can be installed in any river, canal, or waterway that has a drop between 1.5 - 5 m. You can generate electricity using an individual turbine or a network of multiple turbines for higher energy demands, all designed for durability and low maintenance.

Fish-friendly hydrodynamic rotor with flow-optimized blades and low turning speeds.

  • Compact low-noise submerged design.
  • Core unit designed to operate for over 25 years
  • Submersible gearbox and generator outfitted with Double Eagle Burgmann* mechanical face seals that can withstand any type of flood
  • Secondary sealing system with multiple layers of protection against fresh and brackish water debris and sand designed by SKF for continuous heavy-duty use in harsh environments.
  • All rotor and casing parts made from stainless steel used in the food industry
  • Carbon steel parts have an impact- and abrasion-resistant coating
  • Equipped with maintenance-free induction generator from European manufacturers.


Why is Turbulent Better?

Generate 8 times more energy than solar

Hydropower is always there: 24 hours a day, 7 days a week, 365 days a year. Every hour is a peak hour for hydro energy, while solar power is not available at night.

Comparing a Turbulent hydroelectric plant with a solar panel array of equivalent capacity, you will generate 8 times more energy using only 6% of the space

Turbine Models 

The model you can install will depend on the head and flow combination of your stream. Each model has a unique basin diameter to optimally fit diverse stream characteristics.

Delivery of the Turbine Core Unit is consisting of the following components as shown in the diagram.

Underwater Turbine from 5 to 70 kW

In order to check the suitability of your project, we will need a few details of your site:

  • General contact information
  • Enough flow (minimum 1000 L/s)
  • Height difference (minimum 1.5 meter)
  • GPS location (Google Earth)
  • Energy Need (kWh/year)
  • Grid connection (If applicable)
  • Photos and videos

Harness clean energy from rivers or canals that were never viable before and power remote communities and villages with 1 to 200 households, schools, hospitals, small businesses, public infrastructure, and more. 

  • Easy transport on a small truck
  • Generate 40.000 to 240.000 kWh per year per turbine
  • Fast delivery

Unique GIS Software

Turbulent has developed a unique GIS software that can help you to find thousands of potential sites in your region! This innovative tool makes hydropower simpler than ever.

Once the site information is confirmed by a local engineer, different sizes of turbines can be installed to meet the energy need of each location.
Furthermore and as a scalable solution, an interconnected network of turbines along the stream can provide up to multiple megawatts of power to supply higher energy demands.

Turbulent will become a partner in your projects, helping you along the way and providing assistance for site feasibility, installation, commissioning and maintenance training




Minimum site requirements

  • Drop of 1.5 to 5 meter (5 to 16 feet) (2 sequenced turbines are possible if 5 m drop and larger flow)
  • Minimum flow of 1 cubic meter (35 cubic feet)/second constantly available throughout at least 9 months of the year.
  • Road nearby (to avoid unnecessary roadworks and environmental damage)
  • For On-Grid, Feed-in options nearby (ideally under 200m, to avoid lengthy line connections)
  • Ideally: 3G (or better) reception to enable remote monitoring

Single Turbine

The Turbulent vortex turbine makes hundreds of sites possible that were never viable with other technologies. Because of the Smart Concrete foundation design, new sites can be developed without many extra concrete structures.

For a single turbine system, you only need a height difference between the upstream and downstream water level of 1.5 - 5 meters and a flow that is larger than 1 cubic meter per second. 

Multiple Turbine

Our easily scalable manufacturing and highly flexible, low-head design, allows us to harness the max energy potential of your streams. If you have a canal or river with at least 5 meters over 100m distance (and flow larger than 1 cubic meter), we can install multiple, interconnected turbines which—depending on your drops and flow—can generate up to 2 megawatts or more.
