In Atyrau region there was a launch of new power transmission lines built to strengthen the power network of the Western zone of Kazakhstan. Alikhan Smailov, Prime Minister of the Republic of Kazakhstan, took part in the official connection ceremony via teleconference, El.kz cites primeminister.kz.

KEGOC constructed five 220 kV power transmission lines along the route "West Kazakhstan Power Hub - Atyrau - Mangystau" with a total length of about 780 km to increase the network capacity and reliability of power supply to consumers in the Western Zone of Kazakhstan. In the course of works over 4.2 thousand electric poles were installed, expansion of substations "Uralskaya", "Pravoberezhnaya", "Inder", "Kulsary", "Tengiz" was provided, and also a new distribution substation "Karabatan" was introduced. 

As a result of the project realization the capacity of the electric network was significantly increased: on the section "West Kazakhstan energy hub - Atyrau" from 100 MW to 200 MW; on the section "Atyrau - Mangystau" from 50 MW to 200 MW. In aggregate, this doubled the reliability of the Western Zone network. The probability of disconnection of consumers is minimized.

In his speech, Alikhan Smailov noted that this strategically important project is of great importance for energy security and economic development of the Western region.

"It will allow to increase the capacity of electric networks twice, as well as significantly reduce the number of cases of disconnection of consumers in the west of Kazakhstan, including during emergencies at the MAEK power plant," the Prime Minister said.

Strengthening of the power grid of the Western zone will also be the basis for its further integration with the Unified Power System of Kazakhstan. 

As the Chairman of the Board of KEGOC Nabi Aitzhanov noted, the modern power grid equipment used during construction works is characterized by high performance.

"The controlled shunt reactors installed at the Inder substation are a unique complex that stabilizes voltage without switching. It also reduces losses and increases the reliability of operation of long transmission lines and distribution networks, allowing for prompt control of active and reactive power flows," Nabi Aitzhanov said.

Domestically produced metal and reinforced concrete supports, wires, insulators and transformers were used in the construction works. The share of Kazakhstani content amounted to about 70%.
