US interested in pumped storage hydropower projects in Romania, Bulgaria
Minister of Energy of Romania Sebastian Burduja and Minister of Energy of Bulgaria Zhecho Stankov both met with United States Secretary of Energy Chris Wright and discussed bilateral cooperation in projects in their countries including for pumped storage hydropower plants and nuclear power plants. Burduja said studies would be conducted with American support for a string of pumped storage hydroelectric facilities throughout the Carpathians.
At the sidelines of the 2025 Three Seas Business Forum in Warsaw, Minister of Energy Sebastian Burduja held a meeting with US Secretary of Energy Chris Wright about ongoing strategic projects in which American companies are involved. He revealed that state-owned power utility Hidroelectrica has signed a memorandum with the National Renewable Energy Laboratory (NREL) of the United States on cooperation in pumped storage hydropower projects.
The initiative will put Romania “at the forefront of Europe” as it will store green energy throughout the Carpathian mountain range, according to Burduja. Prefeasibility and feasibility studies will be developed with American support, he added.
“In this era of energy transition, we need pragmatic and effective solutions that ensure secure, affordable, and clean energy – in that order of priorities. Romania and the United States share a vision for a common energy future, and our collaboration will significantly contribute to achieving this goal,” the minister stated.
Significant involvement of US companies in strategic energy projects in Romania
Burduja highlighted NuScale’s project for small modular reactors (SMRs) in Doicești and the contract signed with Fluor and Sargent and Lundy for units 3 and 4 at the Cernavodă nuclear power plant. Fluor is also participating in a project for a high-voltage direct current interconnector (HVDC), he pointed out.
The lack of interconnections is bolstering energy prices
The minister noted that American partners are involved in a project for mapping and utilizing geothermal sources for district heating in Bucharest, with support from the European Union’s Modernisation Fund. Namely, Electrocentrale Bucharest (ELCEN) has established cooperation with US-based SAGE Geosystems
Burduja recalled that American platform Transocean Barents is drilling for gas in the Neptun Deep project in the Black Sea.
The Romanian ministry said the two officials discussed the rise of energy prices, attributing it to the lack of interconnections and the challenge of closing coal-fired power plants without viable alternatives. They also touched upon the costs of carbon dioxide certificates and how they affect competitiveness, the announcement reads.
Stankov, Wright discuss possibility of building AI ‘gigafactories’
Bulgarian Minister of Energy Zhecho Stankov separately met with US Secretary of Energy Chris Wright. Bulgaria will be the first in Europe to deploy the American AP1000 technology, Stankov claimed.
The country is preparing to build two more units at the Kozloduy nuclear power plant, in a deal with Westinghouse Electric. State-owned Bulgarian Energy Holding is controlling the project.
The two officials discussed the possibility of building “artificial intelligence gigafactories” to complement the nuclear infrastructure and promote innovation and employment, the ministry said. In addition, Stankov and Wright spoke about projects for new pumped storage hydropower and the exploration of oil and natural gas in the Black Sea.
