The Turbiwatt Company

Turbiwatt has developed turbines specifically adapted to the exploitation of low heads. Since 2010, with the help of the CEA, Turbiwatt has developed a range of products dedicated to run-of-river applications, profitable and efficient from 1.20 m head. The objective was to favour a simple, robust, economical and standardised design to achieve a competitive cost price for low power but without compromising performance.

Today, Turbiwatt has a complete range, producing from 2 to 130 kW per unit with excellent overall efficiency (+/- 80%). Silent and immersed, Turbiwatt turbines are free of noise and visual nuisance. Ultra-compact, their installation is greatly facilitated (generator integrated into the turbine).

With more than 150 installations in a dozen countries (France, Germany, Austria, Japan etc.), Turbiwatt has built up a solid experience in the entire deployment of hydroelectricity projects.

Our Story

Exploiting the considerable potential of low waterfalls.

Turbiwatt was created in 2010 based on the idea that it was necessary to develop specific turbines to exploit low waterfalls. These turbines had to be simple, robust, economical, and standardized. The objective was to offer a competitive cost price but without compromising performance.

As soon as it was created, Turbiwatt invested in R&D, with the support of a private investment fund. Shortly afterward, the T250 turbine (600W) was developed. It initiates the concept that will prevail on all Turbiwatt ranges; constant speed, industrial simplification, and energy directly produced to network standards.

Subsequently, the industrial range currently marketed is launched with the development of the T800 turbine (6 to 55kW).

In 2013, based on technological achievements and the validation of tests on prototypes, a new investment was made to finance the development and marketing of the range with the T400 (2 to 12kW).

In 2016 Turbiwatt was selected by Gruyère Energie (CH) and Romande Energie (CH) to equip reserved flows of large hydroelectric power plants.

In 2017 the development of the T1300 (24 to 130kW) and the innovative grid coupling cabinet are launched. In the same year, Turbiwatt is the winner of a European call for tender by HSE (Holding Slovenske Electrarne, a Slovenian national company) in charge of hydroelectric production.

The first T1300s were installed in 2019 with notable success.

In 2022, thanks to its expertise in low-head hydroelectricity projects, Turbiwatt is launching its turnkey offer and is planning a new, even more, powerful range (the T2000).

As a designer with real know-how of turbines dedicated to low heads, as a French manufacturer and integrator of hydroelectric solutions with its integrated design office, Turbiwatt has become a major player in the energy transition.

The expertise of our engineers

The realisation of a hydroelectric project aiming at the installation of a Turbiwatt turbine requires the realisation of preliminary studies and in particular a feasibility study and an administrative study relating to the water right.

Turbiwatt supports you from start to finish, from the feasibility study to support and maintenance. We offer you full support, including potential and administrative studies as well as assistance in financing your project.

Turbiwatt’s innovation

Dedicated to low heads, the Turbiwatt had to be a Kaplan turbine. The flow rate absorbed by the Kaplan turbines depends on two constructional parameters; the adjustment of the guides and blades as well as the diameter of the propeller. It also depends on the head of the site which is imposed.

In order to respect our objectives of simplicity, robustness, economy, and standardization, our turbine has been freed from custom design and adjustments in operation.

The Turbiwatt is a constant flow turbine with, for each range, a fixed standard propeller and fixed guide vanes. The guide-blade adjustment torque is determined for each site to absorb the available flow for the given head.

The direct drive and the integrated generator complete the specifications of an optimized bulb design. The development of the high-efficiency generator adapted to the different sites becomes the cornerstone of our know-how.

Finally, we have developed our own electrical cabinets for coupling to the grid, allowing a complete solution for hydroelectric power generation.

Simple, robust, economical, and standardized, the Turbiwatt turbine has become, in a few years, the reference for the turbining of low waterfalls.
