The SCHOTTEL INSTREAM TURBINE (SIT) harvests hydrokinetic energy for commercial projects. Using standardized drive trains allows the turbine to be a cost-effective component of customized projects.

Minimum CAPEX

In contrast to other instream energy converters with nacelle weights of 130 t to more than 200 t, a single SIT weighs about 1 t. This results in 1 MW of installed power using about twenty SIT turbines at a weight of only 20 t. The turbine structure is kept simple, avoiding complex subsystems.

Minimum OPEX

The robust turbine layout ensures a long device lifetime, and the SCHOTTEL HYDRO design philosophy guarantees easy access to the turbines for regular maintenance.

Maximum Revenue

Besides low investment and operational costs, high availability of the power plant is required to increase each project’s revenue. The multi-turbine principle of SCHOTTEL HYDRO installations includes redundancy. Together with easy and cost-effective maintenance this ensures high availability. The smart design of platforms additionally increases the energy yield by locating the turbines into an optimum position.


SCHOTTEL HYDRO has summarized the distribution of tidal flow velocities into three flow speed standard classes. These cover a range of reasonable sites, reflected in three turbine ratings sharing the same standard drive train. The customer can choose the best suited device for the proposed project with a reasonable cost. Common parts are an integral part of the SCHOTTEL HYDRO system.
