The power facility built in the Primorsky district of the city will provide high-quality and reliable power supply to more than 70 thousand consumers (housing, social sphere), create conditions for expanding the Hyundai car production, and cover future capacity needs. Rosseti Lenenergo’s investments in the project amounted to 1.4 billion rubles.

The opening ceremony was attended by Alexander Beglov, the Governor of St. Petersburg, Andrey Ryumin, Director General of Rosseti, and Igor Kuzmin, Acting Director General of Rosseti Lenenergo.

The 126 MVA substation is equipped with modern switching and power equipment, including two 63 MVA transformers. 110 kV and 10 kV switchgears are located in closed rooms. This makes it possible to reduce the noise and fire hazard level, provide a high-level protection against negative climatic influences, and minimize the impact on the environment.

Automated control systems and commercial metering of electricity have been introduced, and 100% remote observability is ensured at the facility. In addition, the substation implements adaptive control elements taking into account the internal processes and modes of the adjacent network.

98% of all equipment used in the construction is produced in Russia.

For communication with the main 330 kV Severnaya substation of Rosseti Federal Grid Company of the Unified Energy System, two cable transmission lines with fiber-optic communication lines over 7 km long were built.

“This substation is a perfect gift to our city. It will ensure the reliable power supply to residential and social buildings in the Primorsky District. Including the Yuntolovo microdistrict under construction. 70 thousand people live there. The substation will create the necessary power reserve for connecting new consumers to the power supply system. In the harsh conditions of the pandemic, Rosseti and Lenenergo fulfilled all their investment obligations”, said Governor Alexander Beglov.

“Highly-developed infrastructure is a basic condition for creating a comfortable life and economic growth. A comprehensive project for the development of a 35-110 kV network in the Petrogradsky district of St. Petersburg will be completed shortly, and we are planning to commission a new 110 kV Graftio substation in the Central district of the city. Like today’s launch of the Konnaya substation, these measures are aimed at solving the main task - creating a reliable and efficient energy system that will help to realize the potential of the Northern Capital”, said Andrey Ryumin.
