The Porțile de Fier I Hydroelectric Power Plant is one of Hidroelectrica’s most important production units, contributing significantly to the company’s total electricity generation. Located on the Danube River, the plant has an installed capacity of approximately 1,166 MW on the Romanian side, making it the largest hydroelectric power plant operated by Hidroelectrica. Under normal hydrological conditions, it can produce an average of 4 to 5 TWh of electricity annually, representing an important component of the company’s total production. The size and role of this capacity in Hidroelectrica’s production structure mean that the modernization and maintenance of the technical performance of its equipment remains a priority in the company’s investment programs.
We recall that Hidroelectrica is the largest producer of electricity from renewable sources in Romania and one of the most important players in the energy sector in South-Eastern Europe. With a portfolio of over 6.3 GW of installed capacity in hydropower plants, combined with the Crucea wind farm, the company contributes to national energy security and to achieving the decarbonization objectives established by EU policies.
