Event to report: Non – reimbursable financing over 56 million euros

The National Power Transmission Company Transelectrica SA has got 56.2 million euro through the REPowerEu component of the National Recovery and Resilience Plan (PNRR), which has recently been approved by the European Union Council, with the purpose to finance three essential investment projects, two of them being dedicated to the subsidiaries SMART SA andTeletrans SA.

The objective of the investment financed through REPowerEu is to raise flexibility and to solve the blockages in the electricity grid in order to accelerate the capacity integration of additional renewable energy capacities and to raise the resilience degree of the grid while strengthening the cyber security through a better ability to react to cyber attacks.

The total investment approved has a value of 56,237,200 euro and consists of three sub-investments:

1. "Installing photovoltaic power plants (CEF) and electrical energy storage installations intended to supply the internal services installed in Transelectrica's power stations", with a grant of 29,557,000 euro. This sub-investment consists of installing in 29 transformation power stations of the total of 81 power stations from the power transmission grid, of some electricity production installations through photovoltaic plants. The investment is an off grid one and within this investment the photovoltaic power plants and the storage batteries will be used only to supply with electrical energy a part of the internal services of the stations.

By implementing these systems of collocated off-grid solar panels with electricity storage, the aim is to achieve a reduction of at least 50% of Transelectrica's own electricity consumption in 29 stations, compared to the year 2022. It will also result in a reduction in greenhouse gas emissions of 2,610.93 tons of CO2/year. The deadline for completion is until June 30, 2026.

1. "The refurbishment of SMART SA – subsidiary of CNTEE Transelectrica SA", with a grant of 18,240,000 euro. This sub-investment aims at endowing SMART SA with the latest generation equipment and tools that uses clean technology, in order to ensure some maintenance services at the highest standards, suitable for a transmission and power operator, as well as the digitalization of the maintenance services offered to the national energy infrastructure through the implementation and development of software solutions.

If any questions arise related to the accuracy of the information contained in the English version, please refer to the Romanian version of the document which is the official version.

The sub-investment consists of:

• endowing SMART SA with suitable technological equipments to ensure the maintenance services of the power transmission grid at the highest quality standards;
• the digitalization of the maintenance services provided by SMART SA for the Power Transmission Grid in Romania.

The new equipments will allow SMART SA to use the LST (working under voltage) technology which implies that the interventions to the lines and the stations of the power transmission grid will be made without disconnecting them from voltage and this ensures the continuity in the supply of electricity to consumers. All equipments will be used only to ensure the maintenance of the power transmission grid by SMART SA, as well as within the process of connecting the producers from renewable sources to the National Power System.

This sub-investment will have positive effects on the quality of the maintenance services provided by SMART SA for the national power transmission grid by reducing with 50% the average number of hours of intervention and the number of interventions. Thus the refurbishment of SMART SA will strengthen the safety and stability of the National Power System and the power transmission grid which contributes to the ensuring of the energy security by Transelectrica as the national transmission and system operator.

The implementation of this sub-investment shall be completed by December 31, 2024.

1. "Optimizing the communication network and creating a data centre – Teletrans SA, subsidiary of Transelectrica SA", with a grant of 8,440,000 euro. The sub-investment aims at raising the cyber resilience of the power transmission grid and of the National Power System by modernizing the communications network (equipment and software) and creating a data centre. The equipment to be purchased within the project will have as a result the increase of the level of technical availability of the optical fiber infrastructure up to 99.5%, bringing a direct contribution to the ensurance of safety and stability in operation of NPS.

The implementation of this sub-investment shall be completed by March 31, 2026.

The implementation of these investments will bring a significant contribution to the strengthening of the Power Transmission Grid of Romania, meaning that it will sustain the phased decarbonisation and the progressive integration of renewable sources, while guaranteeing the efficiency and security of the electricity supply in compliance with the regulations in the field of environmental protection and climate change.
