It's in the Water

The movement of the world’s water – whether in open water or inland – provides a vast store of kinetic energy, which can be harnessed to generate electricity. 

An unprecedented opportunity exists to capture untapped in-stream resources that were previously unattainable in canals, rivers and marine environments.

Instream’s technology creates a cost-competitive renewable energy source with minimal environmental impact, resulting in a smarter way to generate clean electricity for renewable power projects.

Instream is developing a complete hydrokinetic power solution consisting of groupings (or “arrays”) of vertical axis hydrokinetic turbines (VAHTs), simple, low-cost devices that convert the kinetic energy in moving water into electricity.

Instream hydrokinetic power generation technology has the ability to produce energy without the need for dams, diversions, or reservoirs. This allows for a water-based renewable energy source with less environmental disruption, a lower cost of engineering, construction and maintenance, less safety risk, and reduced regulatory issues.

Instream’s pilot projects provide valuable insight into the interactions between multiple turbines. The data obtained will allow Instream to optimize multi-turbine installations.

A Better Solution – Hydrokinetic Power Generation
The Engineered Advantage

Instream’s versatile technology is applicable in both inland water and near-shore tidal applications inaccessible to conventional technologies.


The use of smaller turbines and standardized support structures allow for commoditization and cost effective deployment and maintenance. Networking devices together allows projects to scale to any size.


A non-submerged system is more cost effective and simplifies deployment. Instream’s turbines have the drivetrain and electronics above water which reduces risk and improves access for maintenance.

  • Patent-pending

Instream Energy Systems technology provides a breakthrough approach to clean power generation that unlocks vast untapped in-stream and tidal resources that were previously unattainable.

The Instream solution produces power for energy consumers such as commercial, residential, agricultural or public facilities. Utility-scale projects install multiple Turbine Deployment Units which network together to create a Turbine Array at a given location. At the utility scale, hydrokinetic energy facilities generate a large amount of electricity for transmission from a near-shore tidal energy or in-stream river site to power users through the grid.


In-stream Canal - Constructed waterways, such as irrigation canals and aqueducts provide an opportunity to use existing infrastructure for power generation. Canals can be found throughout the world and contain large amounts of untapped renewable power. Instream turbines do not damage canals or affect the water flow speeds. Many canals are concrete lined creating high water velocities. 


In-stream River - Rivers provide an optimal environment for Instream technology without the need for damming or diversion. Instream turbines are safe to deploy in sensitive environments including fisheries and avian habitats; and safe to use in shared waterways because the turbines can be installed in varying array configurations that avoid interference with recreational or navigational users.


Marine Environments – Instream turbines convert the power of ocean currents to produce electricity. Instream turbines are safe for use in sensitive marine environments and can be placed in near shore tidal environments, ocean inlets and estuaries where there is a moderate tidal flow.

Pioneering VAHTs for Under-Utilized Waterways
Turbines in Action

Hydrokinetic conversion systems are like “windmills in the water” producing renewable electricity by harnessing the kinetic energy of moving water without the need for dams, diversions, or reservoirs.


Since water is over 800 times more dense than air, the world’s free-flowing rivers, constructed waterways, tides, waves, and ocean currents represent a powerful, highly-concentrated, untapped clean energy resource.


Hydrokinetics could capture as much as 15 percent of the global electricity market by 2030.
