SU-EnergoGrupp JSC has completed the construction of overhead line 220 kV overhangs to provide power to the Yaroslavl CHP.

SU-EnergoGrupp put under voltage two-circuit entry of 220 kV “Yaroslavskaya - Tveritskaya, Yaroslavskaya - Yaroslavskaya-2” power lines with a length of 29, 5 km. The commissioning of these lines was the second (final) stage of construction of power lines to ensure the issuance of capacity of the Yaroslavl (Huadyan-Teninskaya) CHP (470 MW). The customer is FGC UES - MES Center. The contract value amounted to 1.8 billion rubles.

As part of the project, the supports were replaced - 68 anchor-angle and 63 intermediate supports were installed. The construction took place mainly on agricultural land, therefore, to reduce the area of land plots used for mounting power lines, modern supports of a multifaceted type were used. These designs have several advantages, including durability and ease of maintenance. At the same time, the power equipment was modernized, the latest microprocessor relay protection and automation devices were installed at the Yaroslavskaya, Tveritskaya and Tutaev substations.
