The HPP Zrnovci is a typical hydropower plant built in the era of a fast electrification in former Yugoslavia. Its layout became obsolete during years of operation and was leading to unbearably high operation costs.
The rehabilitation consisted of complete turbine and generator replacement, new substation, automation and transformer as well as major overhaul of plant auxiliary equipment such as gates and valves.
Hydropol was responsible for complex research, study and design, specifications, contracting and legal framework. It also provided full project management, site and quality supervision and commissioning.
