Romania is making significant strides in its energy infrastructure with the renewed momentum of the Tarnita-Lapustesti pump-storage hydropower project. This initiative, which has faced numerous delays since its inception, is now set to progress following a partnership between Hidroelectrica and the French energy giant EDF. The collaboration aims to develop a facility with a capacity of 1,000 MW, marking a pivotal development in Romania’s energy landscape.
The joint venture will see both companies holding a 50% stake, governed by a shareholders’ agreement that will outline operational and governance structures. This new entity will be tasked with the development and operation of the pump-storage plant, which is crucial for enhancing Romania’s energy security and operational efficiency.
Government studies have previously indicated that the project offers several advantages, such as improved system stability, enhanced reserve capacity, frequency regulation, and better integration of renewable energy sources. These benefits are expected to bolster Romania’s position within the European single electricity market by increasing network reliability and operational security.
The renewed interest in the Tarnita-Lapustesti project coincides with broader discussions about large-scale energy storage solutions. Previous negotiations have included various stakeholders such as EDF, Japanese firm Itochu, and representatives from the Romanian Government. Additionally, support from the European Bank for Reconstruction and Development (EBRD) has been instrumental in facilitating studies on financing options for large-scale storage initiatives like this pump-storage project.
Strategically located approximately 30 kilometers from Cluj-Napoca, along the Somes River, this facility is poised to become Romania’s largest pumped-storage hydropower plant. Initially proposed in 1979, its realization would significantly enhance the country’s energy flexibility and storage capabilities, addressing both current needs and future demands in an evolving energy market.
