The fifth hydraulic unit modernized by equipment manufacturer Power Machines has been successfully placed into operation at the Iron Gate (Djerdap)-1 hydropower plant in Serbia.

The work was completed under a contract signed by Power Machines, Elektroprivreda Srbije, and Iron Gate (Djerdap) Economic Society which covers  the renovation and upgrade of the hydro plant’s six units.

As of today, five of the six hydraulic units have been successfully put into operation, and the manufacturing of equipment for the last unit is in its final stage. The completion of the project is scheduled for 2021.

As a result of the work, the operation lifespan of each updated unit was extended by 30 years, and the capacity was increased from 174 to 201MW.

During modernization, Power Machines manufactured new units for turbines and generators, equipped the units with modern turbine control systems and generator excitation systems. Part of the equipment was modernized at the Power Machines production facilities in St. Petersburg.

The former units were manufactured in the 1970s by the Leningradsky Metallichesky Zavod and Electrosila, which are currently a part of PJSC Power Machines. Following decades of successful operation, Serbia wanted the modernization to be carried out by the original equipment manufacturer.
