IOZE hydro – turn water ~ into profits

Hydropower – we provide effective advice for those that wish to invest in hydro power plants (HPPs). We are involved in the project from the very moment of appraising the potential construction site for its suitability in terms of the energy generation needs, investment management, delivery of the technology, up to the turnkey delivery of HPP and its further service.


Enerko energy – turn plans ~ into reality

General Contractor – we deliver a turnkey objects, often in a “design-and-build” formula. Our group is responsible for all the processes necessary to complete the investment. We are a contractor in complex investments that require specialised skill and action to complete.

Zabrzeż HPP has a generation capacity of 0.5 MW. Energy is being produced by two Kaplan vertical turbines with rotor diameter of 1670 mm. Thanks to the powerplant being fed through derivational channel that diverts flow of the river, there is no need to build any kind of damming across the river that could restrict the biological flow of the river.


HPP Sulejów is an example of a hydropower plant with a very low head, where thanks to a multistage flow control, the plant has been optimised to operate in variable flow conditions. Energy is generated by four generating sets that include 2 semi-Kaplan and 2 propeller-type turbines. The total generation capacity of this HPP is 0.2 MW


HPP Srock - two dammings, two plants. One object has received a Kaplan turbine, the other has gotten an active fish-pass in form of Archimedean screw with generation capabilities installed.
