Verdant Power, LLC, is the world-wide expert and leader in developing and commercializing free-flow or kinetic hydropower systems – modular and scalable hydroelectric power without dams – a breakthrough in the renewable energy business having critical global implications. Among its intellectual properties, the Company has a patented axial-flow turbine blade design that operates in the widest range of water velocities and at the highest operational efficiencies. Verdant Power’s leadership position is demonstrated in the status of its New York City’s East River project, a precursor to a commercial project, with built and tested turbines due to be permitted and deployed in 2005. Additionally, its management team has developed a recognized leadership presence within the U.S. hydropower research, development, and public policy community. For the East River project, the precedent-setting Verdant ruling by the Commissioners of the Federal Energy Regulatory Commission (FERC) established the Commission’s support for innovation in kinetic hydropower. Further, due to Verdant Power management’s advocacy, kinetic hydropower is being added to the U.S. Department of Energy’s 25-Year National Energy Forecasting Models.
The Company’s advantages lie in its business approach to the industry. In contrast to a technical engineering approach, Verdant Power is a systems integrator and a developer applying market driven innovations to the sustainable energy marketplace. As a systems integrator, the Company identifies and applies the most appropriate free-flow technology to optimally address customer requirements. As a site developer, Verdant Power develops projects of 1-10 megawatts (MW) using free-flow turbine systems that generate utility and village scale electric power from natural underwater currents. The systems do not require civil works or any water impoundments. Currently, Verdant Power offers a “water to wire” Kinetic Hydro Power System (KHPS) using two standard system models: 5-meter and 2-meter axial-flow turbines with 35 and 10 kilowatt (kW) generators, respectively.
Following commercialization, Verdant Power will generate revenues through development and sale of facilities to third-party owner/operators. The Company will market, design, assemble, and install free-flow turbine systems to site operators and/or power producers targeting costs as low as US $2,000 per kilowatt—installed. Internationally, the Company will leverage its intellectual property and expand projects through regional strategic business partnerships, generating royalty and service revenues. The Company is currently in discussion with major strategic partners in the United Kingdom, Canada, Brazil, Japan, India, and China. Major power industry studies demonstrate Verdant Power’s role as a market leader in small-scale hydro assessment and integration. Unlike its competitors, the Company is uniquely qualified and able to offer complete products, services and solutions – to convert flowing water into useable electricity. Verdant Power’s systems have inherent economic benefits. The absence of civil works and unattended operations mean that the Company’s installation and operation & maintenance costs will be lower than those of many of its competitors. In addition, short construction periods and low up-front capitalization costs mean fewer financial hurdles and higher returns on investments to developers.
Instream Energy Generation Technology (IEGT) - also called free-flow hydropower technology or kinetic hydro energy systems - generate electricity from the kinetic energy present in flowing water. The systems may operate in rivers, manmade channels, tidal waters, or ocean currents. IEGT systems utilize the water stream's natural pathway. They do not rely upon the potential energy of artificial water-head, created, for example, by impoundments such as dams. They do not require the diversion of water through manmade channels, riverbeds, or pipes, although they might have applications in such conduits. IEGT systems do not require large civil works; however they can be placed in existing tailraces and channels.
In general, there are several main differences between design-developer companies' IEGT systems: drive train and generator styles; mounting/anchoring arrangements; and geometries of the turbine or kinetic energy conversion device:
Axial-Flow Rotor Turbine: The design of these turbines consist of a concentric hub with radial blades, similar to that of a windmill. Mechanical power is applied directly through a speed increaser to internal electric generator, or through a hydraulic pump that in turn drives an onshore electric generator.

Open Center Fan Turbine: A flotation chamber and frame holding two donut-shaped turbine blades rotate in opposite directions in the current. Rotation of the blades drives hydraulic pumps along the edge, which in turn, drive a conventional AC generator that produces electricity.
Helical Turbine: This turbine is a low head, reaction cross-flow hydraulic turbine. The blades have hydrofoil sections that provide tangential pulling forces in the cross water flow. These forces rotate the turbine in the direction of the leading edge of the blades. Thus, the direction of turbine rotation depends only on orientation of blades and not on direction of fluid flow.
Cycloidal Turbine: It is a paddle wheel with articulating blades. The turbine works by placing a blade broadside to the flow while the opposing blade is feathered to the local flow. Thus, it allows the blades individual lift and drag to be optimized giving the system the best overall performance.
Lift or Flutter Vanes: Resembling a Venetian blind, the generator is powered by a flutter or lift-vane type of turbine that consists of a parallel linkage holding a number of large hydroplanes. The Generator produces electricity using the linkage oscillatory movement of hydroplanes driven by flowing water.
