Transelectrica has proposed an investment program of over 130 million euros for 2025 – the most ambitious in recent years, and by 2030, it is planned to build over 740 km of new overhead power lines, with total financing of over 380 million euros, from its own sources and European funds.
In the last three years, Transelectrica has consistently increased the budgets dedicated to the modernization and development of the network. If in 2022 the investments amounted to approximately 90 million euros, in 2023 they increased to 93 million, and in 2024 they reached 106 million euros. In the period 2022-2024, 18 major projects were completed, and this year another 22 investments are in various stages of implementation or preliminary (documentation, procurement).
“We are facing a historic process of transforming Romania’s energy infrastructure. We have the obligation to implement these projects, for national energy security, for the integration of green production and for a competitive and European energy market,” says the president of the Transelectrica directorate, Ștefăniță Munteanu.
Transelectrica marks its 25th anniversary with an unprecedented wave of investments in Romania’s energy infrastructure. The national electricity transmission operator is accelerating the pace of works and preparing strategic construction sites, aimed at strengthening energy security, facilitating the integration of renewable production and increasing interconnectivity with neighboring states.
The electricity transmission network currently consists of 81 electrical transformer stations and approximately 9,100 kilometers of high-voltage lines.
Approximately 75% of the energy installation park has already undergone a complete re-engineering and modernization process, and the rest is in the process of being fully re-engineered. This category includes two stations that will be modernized in a digital concept, Mostiștea and Alba Iulia – two projects financed by the Modernization Fund, but also others that are in preparation for initiating the modernization processes.
In addition, Transelectrica is preparing the construction of the 82nd station – Ostrovu Mare, which will facilitate the evacuation of energy from the Porțile de Fier 2 hydroelectric power plant, with the completion in June of the 220 kV Ostrov-RET Overhead Power Line.
In the last two years, Transelectrica has built 60% of the new lines built in Romania in the last 20 years.
Among the key completed projects are:
• The 400 kV Cernavodă–Stâlpu line (160 km), inaugurated in 2022,
• The 400 kV Porțile de Fier–Reșița line (117 km), completed in 2024,
• Connections to Medgidia Sud Station (28 km), put into operation in 2024.
By 2030, it is planned to build over 740 km of new overhead power lines, with total funding of over 380 million euros, from own sources and European funds.
Transelectrica has attracted 649 million euros in European funding in the last three years, from the Modernization Fund, the Sustainable Development Program and PNRR-REPowerEU. At a strategic level, the company is analyzing HVDC cable projects, including the Georgia-Romania submarine interconnection and an east-west project on national territory.
Romania today has an interconnection capacity of 4,000-4,500 MW, and the objective is to reach the 7,000 MW threshold by 2030. This year, the company initiated major projects to increase interconnection capacity, including the 400 kV Timișoara-Arad OHL, the 400 kV Gădălin-Suceava OHL, and the 400 kV Suceava-Bălți OHL.
The main objective of the transmission and system operator is to develop the electricity grid to allow the connection of new energy production units, especially renewable ones. In this context, new storage capacities also play a major role in ensuring operational safety and network flexibility. Transelectrica estimates a need for 4 GW of storage capacities by 2030, compared to the 249 MW currently in place. By the end of the year, 250 MW of new capacities are to be installed.
The 2024-2033 Development Plan, approved by ANRE, foresees total investments of 9.49 billion lei – over 2 billion lei more than the previous plan. It aims to modernize facilities, accelerate the integration of renewable energy and increase interconnection capacities.
