New power and another 30 to 40 years of life operation for Hydro Power Plant Zvornik will be provided by revitalization project started in 2015. Numerous national and international companies take part in realization of this project and Elnos Group is leading the national contractors. Elnos Group is the Main Subcontractor of Austrian company Voith, which signed a contract with EPS on revitalization of the hydro power plant, i.e. replacement of 4 turbine generators. Apart from replacing generators, i.e. turbine and generator, project also includes construction of new 110 kV switchyard along with new block transformer, entire replacement of equipment for generator voltage, entire replacement of controlling system, electrical protection systems as well as replacement of accompanying subsystems. Once the project completes, Hydro Power Plant Zvornik, which has been operational for 61 years, shall be entirely new hydro power plant in the reference to electrical-mechanic equipment. Elnos Group with Voith, and all the national partners of the project, takes part in realization of whole revitalization project of the hydro power plant, Namely, we take part in performance of construction, mechanical and electrical assembly works as well as in testing and commissioning complete electrical-mechanical equipment. Works performed by Elnos Group have been intensified in the past month and we have seen actual results. The most demanding works include installation of cabinets for new equipment of generator voltage. As for the Investor, we are also very satisfied with time schedule and professionalism of work performance by Elnos Group. Revitalization works shall last for four years – one year for each individual generator. Specific feature in this project is that we perform works on one generator, whereas other three are operational. It is important to mention that diameter of new turbine runner is bigger than the existing one, which demanded voluminous extension construction works, i.e. installation of new lining for turbine runner. Our further tasks are connected to electrical assembly works of installing high-voltage and medium-voltage equipment as well as production, installation and testing cabinets for electrical protection. Apart from this, we take part in performance of all stages of works within assembly of turbine, controlling system and all the other accompanying systems. There are 10 workers of our profession hired for these works at the moment. We are currently working on the distribution plant, where entire equipment is and where new transformers were installed. After revitalization, Hydro Power Plant Zvornik will be state-of-art hydro power plant in Serbia and region. Total generator power shall be increased, hence production of electrical power as well, , for 15 per cent or 70 million kilowatt hours a year. Practically, revitalization provides one more generator since total power of the hydro power plant was increased from 96 MW to 124 MW.
