The acquisition is part of the company's investment program to modernize the equipment and maintain the technical performance of the Iron Gates I Hydroelectric Power Plant, the most important production unit in Hidroelectrica's portfolio.
„The modernization and consolidation of the energy infrastructure is a strategic priority for Hidroelectrica. The acquisition of these high power transformers for Iron Gates I is part of the company's constant effort to ensure the reliability of the facilities, increase operational efficiency and maintain the highest safety standards in the operation of vital energy objectives for the SEN. We continue to invest in modern technologies and in projects that directly contribute to Romania's energy security”, said Bogdan Badea, CEO of Hidroelectrica.
The Porțile de Fier I hydroelectric power plant is among Hidroelectrica's most important production units, contributing significantly to the total volume of electricity generated by the company. Located on the Danube River, the plant has an installed capacity of about 1,166 MW on the Romanian side and is the largest hydropower plant operated by Hidroelectrica. Under normal hydrological conditions, it can produce on average between 4 and 5 TWh of electricity annually, representing an important component of the company's total production. The size and the role of this capacity in Hidroelectrica's production structure make the modernization and maintenance of the technical performance of its equipment a priority in the company's investment programs.
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 more than 6.3 GW of installed capacity in hydropower plants, cumulated with the Crucea wind farm, the company contributes to national energy security and to achieving the decarbonization targets set by EU policies.
