Domnești Station, the most important electrical transformation station in the capital area, to complete the refurbishment process

The refurbishment project of the 400/110 / 20kV Domnești substation, a total investment of about 25 million euros from the own funds of Transelectrica SA, is currently being carried out in 95%, the completion of the works being expected by the end of June.

The investment involves upgrading the station at all voltage levels, in order to bring it to a degree of safety and reliability appropriate to the importance of the area served. The members of the Company’s Management Board and members of the Supervisory Board visited the 400/110/20 kV Transformation Power Station site, where the last works from a refurbishment process that lasted approximately 3 years are being performed.

Cătălin Nițu, President of the Transelectrica Directorate: “The refurbishment works of the Royal Station were of a high degree of complexity, especially because at the same time it was necessary to ensure the continuity and supply of consumers and the safety of the National Electric Power System. It is very important to mention that the technological level to which the station is brought is an advanced one, being implemented the GIS (Gas-Insulated Switchgear) technology for both the 400 kV substation and the 110 kV substation. Domnești station will be one of the most modern stations in the electric transmission network in Romania. In the last year, although it was a difficult period in the context of the pandemic, we managed to bring to the final stage this extremely important investment for the National Power System. Bucharest needs security in its electricity supply and only substantial investments in energy transmission infrastructure can guarantee this. The Company’s management maintains its commitment to investment, in order to guarantee the performance of a public service at high performance standards ”

The investment objective is part of the extensive process carried out by the Company to consolidate the electricity transmission infrastructure in the Bucharest area, in the context in which Ilfov County together with Bucharest is the most concentrated area of ​​electricity consumption in the country, respectively about 15% of total national consumption.

The 400/110 / 20kV Domnești Transformation Power Station is one of the important nodes of the National Energy System (SEN) in terms of electricity supply to the Capital, together with the 400/220/110/10 kV Bucharest South Power Station and the South Station Electric 220/110/10 kV Fundeni.

The station represents both one of the injection points in the distribution network of the Municipality of Bucharest, and a power transit node between the Oltenia, Muntenia and Southern Transylvania areas. The 110 kV Domnești substation was put into operation in 1980, and the 400 kV substation was put into operation in 1982. Of the three stations in the Capital area, the 400/110 / 20kV Domnești Electric Station is the last to go through the modernization process, being preceded by the refurbishment of the 400/220/110/10 kV Bucharest South Power Station (2006-2009; 2014-2015) and the modernization of the 220/110/10 kV Fundeni Power Station (2006-2007).
