“CHA Mălaia, CHE Călimăneşti CHE Ioneşti, CHE Zavideni and CHE Drăgăşani CHE stations are in operation for 35 years and the equipment is physically and morally outdated. By completing modernization work, we will have a new lifecycle of at least 30 years for these installations. We view 110 kW hydro power plants in Râmnicu Vâlcea as an integrated unit energy system. We want the equipments mounted to be identical so that they can be easily operated by specialists with minimal operating costs and easy maintenance. We are very interested in everything that means uniformity and optimization, and we want this policy to be widely applied. In this case, uniformization also allows for interoperability, interchangeability of equipment, as well as unitary integration into the SCADA system”, says Bogdan Badea, President of the Hidroelectrica Directorate.




The winning bidder undertakes to contract to upgrade the stations within no more than 12 months and with a maximum immobilisation rate of eight days / station. The tender procedure led Hidroelectrica to a saving of over 580,000 lei compared to the initially estimated 4,998,020 lei.
