ESO put into operation the completely reconstructed 110 kV substation Targovishte 2

The completely renovated and reconstructed 110 kV open switchgear of the "Targovishte 2" substation of ESO was put into operation in the presence of the Minister of Energy Rosen Hristov. The reconstruction of the substation, part of the implementation of the large-scale project of the Electricity System Operator "Digital transformation and development of ESO information systems in the conditions of low carbon energy", co-financed by the EU Recovery and Sustainability Mechanism, began in 2022 and is in general value BGN 3,100,000.

Substation "Targovishte 2" 110/20kV, put into operation in 1984, provides power supply to the city of Targovishte, the Southern Industrial Zone and 17 more settlements on the territory of the municipality, as well as to over 25 thousand customers of "Electric Distribution North". The "Targovishte 2" 110/20kV substation is located on an area of nearly 6,000 acres and operates with one 110kV open switchgear and one 20kV indoor switchgear.

The substation is an important part of the electricity transmission network of Bulgaria, ensuring the transmission of electricity in the direction of Southern Bulgaria, through the 110kV power line

"Belomortsi" with a connection to the "Omurtag" substation, and through the 110kV "Vabel" power line and the connection to the "Khan Krum" substation ensures the transmission of electricity between Northern and Southern Bulgaria. Its role is also essential for the integration of electricity produced by renewable energy sources.

The reconstruction of the open 110 kV switchgear of the substation will contribute to increasing the security of the electricity supply in the region and increasing the possibilities of connecting new generating capacities to the medium voltage network.

In 2021, an automatic control system was built in the "Targovishte 2" 110/20kV substation and was introduced to control from the reference point in the city of Varna.

The project for "Digital transformation and development of ESO's information systems in the conditions of low carbon energy" is part of the implementation of the measures laid down in the country's National Plan for recovery and sustainability. Within the project, the Electricity System Operator has already invested over BGN 130 million for the construction of remote-control systems. Five support points are in operation throughout the country, from which the company's 150 substations are automatically managed. By the end of 2024, all 265 ESO substations are planned to be remotely controlled from a base station.
