Power engineering commissioned the largest power transmission line in the Far East

On September 6, 2014, OJSC Far Eastern Energy Management Company (DVEUK) put into operation the largest power transmission line (PTL) in the Far East, according to the correspondent of the Golden Horn.

In particular, the 220/110/10 kV Peleduy substation (126 MVA) and the 220 kV Lensk - Peleduy power transmission line (434 km) in the Western Energy District of the Republic of Sakha (Yakutia) were put under operating voltage.

Thus, the last start-up complex of the 220 kV transmission line "Chernyshevsky - Mirny - Lensk - Peleduy" with a tap to the oil pumping station (OPS) N14 was put into operation.

Almost 35,8 billion rubles were allocated from the federal budget for the project and about 570 million rubles of own funds of DVEUK, said Dmitry Selyutin, Deputy Director General of DVEUK for investment and development.

The length of all sections of the line is 1,5 thousand km, the total capacity of the constructed stations is 352 MVA.

The high-voltage line uses the capacity of the Vilyuisk HPP and Svetlinskaya HPP cascade (total power over 1 GW) to supply power to the south-west of Yakutia and the north of the Irkutsk Region, including ESPO facilities (oil pumping stations No. 12,13,14).

The project was launched at the end of 2010, construction and installation work lasted 36 months (from July 2011 to June 2014), and up to 1,6 thousand people participated in them simultaneously.

During the construction period 158 299 tons of materials and equipment were delivered along rivers and winter roads, 480 000 tons of inert materials (CBC, crushed stone, sand) were transported from the quarries developed at the construction site.

This line has a high economic, economic and social significance for the territory.

Existing power lines with a voltage of 110 kV 1960-1970. The buildings produced two regulatory deadlines and exhausted their capacity. Moreover, outdated power transmission lines on wooden supports were the most overloaded in the Yakut power system, therefore, during the period of maximum loads to maintain the voltage, diesel power stations were put into operation.

Dmitry Selyutin noted that over the past five years, DVEUK, in the most difficult climatic conditions, built more than 1800 km of modern power grids and five powerful substations. Thus, in record time, it was possible to eliminate the 40-year lag in the development of the energy infrastructure of the south-west of Yakutia.

For the further development of the electric grid complex of the region, a number of design solutions for the centralized power supply of the Eastern Gas Program facilities are being considered.

The main one is the project "Construction of a 220 kV overhead line Mirny - Chayandinskoye oil and gas condensate field - Talakanskoye oil and gas condensate field - Peleduy, Republic of Sakha (Yakutia)" with a length of 620 km, with a substation capacity of 628 MVA and a total cost of 18,7 billion rubles.

OJSC "Far Eastern Energy Management Company" implements investment projects to develop the power infrastructure of the Far Eastern Federal District.

The company's investment program in 2009-2011 amounted to 25,88 billion rubles, in 2012 years - 18,27 billion rubles, in 2013 years 10,95 billion rubles was invested.
