Transelectrica to Reconfigure Energy System and Power Transmission Grid

20 Strategic Projects


Transelectrica is preparing itself for a reconfiguration of the energy system and of the power grid in line with the new directions established under the European legislative packages ‘Green Deal’ and ‘Fit for 55’. To ensure the gradual tradition to a carbon-neutral economy, the pace of development of the Power Transmission Grid (PTG) needs acceleration of investment implementation. Therefore, the company aims that the targets of achieving the investment plans exceed those already scheduled.


Over the past month, Transelectrica has analysed the status of projects and prepared an open list of 20 projects of national importance in the field of electricity, for which the simplification of implementation processes is required.

The current development of the Power Transmission Grid (PTG) requires expediting the stages of power infrastructure projects to provide gradual transition to a carbon-neutral economy. Energy transition requires a quick adaptation of the power transmission grid and intensification of its expansion pace provided in the 2020-2029 PTG Development Plan.

In this context, the Romanian Government has recently approved, at the proposal of the Secretariat General of the Government – the public supervisory authority of CNTEE Transelectrica SA, a Memorandum including an Action Plan of the Company providing for the implementation of investment projects essential for strengthening the Power Transmission Grid.

Moreover, several meetings have been organized lately between representatives of the Secretariat General of the Government, of the Ministry of Energy and of CNTEE Transelectrica SA. The discussions have led to the common conclusion on the need to simplify the process of implementation of some projects of national importance in the field of electricity.

Consequently, Transelectrica has prepared an open list of strategic projects, which will allow the flexibility of the Power Transmission Grid. The company’s proposal includes 20 projects, some of which are already in progress, for which it is necessary to accelerate the implementation pace.

  20. New alternating current and direct current lines discharging the onshore and offshore wind power output in Dobrogea region, namely the output generated by Unit 3 and Unit 4 of Cernavoda Nuclear Power Plant, along the Tuzla – Podisor and Podisor – Corbu – Hurezani – Hateg – Recas – Horia – Nadlac routes

For this purpose, both central public authorities and Transelectrica will take steps in the near future to speed up the implementation of the above-mentioned projects, so that Romania reaches its European targets for the time horizon 2030-2050.
