OREANDA-NEWS. On 04 June 2009 was announced, that “Kazakhstan Electricity Grid Operating Company” JSC had successfully completed the next phase of Project “Construction of 500 kV Second Transmission Line of Kazakhstan North-South Transit”, being implemented under the state program “30 Corporate Leaders of Kazakhstan”.

At 500 kV Agadyr substation (Karaganda Oblast), 500 kV OHTL Agadyr-YuKGRES section was solemnly energized with the participation of Karim Massimov, Prime Minister of the Republic Kazakhstan.

Commissioning of this section will strengthen reliability of power supply to the consumers in the South of the country and in Almaty owing to the increase of transmission capacity of “Kazakhstan North-South” transit by 180 MW.

By November 2009 KEGOC plans to complete break-through project and energize the second transit lines by increasing the volume of southward electricity transmission from 730 up to 1350 MW – Kanat Bozumbayev, President of KEGOC JSC, pointed out at the commissioning ceremony.

The works under 500 kV OHTL Agadyr-YuKGRES section with the length of 386 km started in 2007. The following components were implemented under the Project:

• Extension and upgrading of existing 500 kV Agadyr, YuKGRES substations.

• Construction of 500 kV high-voltage overhead transmission line with optical ground wire.

• Providing with the required quantity of relay protection, automation and emergency automation devices.

• Providing with the dispatch and process control facilities.

• Providing with telecommunication network facilities.

For the first time in the Republic of Kazakhstan at 500 kV Agadyr SS, controlled shunt reactor (CSR-500 kV) is installed. Using of innovation equipment stabilizes the operating mode of transit electric networks, and considerably reduces the intensity of switching equipment depreciation. On the whole, 3 CSR will be installed at 500 kV YuKGRES SS and Agadyr SS.

General contractor on construction of 500 kV OHTL Agadyr-YuKGRES – DALEKOVOD company (Croatia), engaged to the maximum the domestic companies for subcontracting (construction and erection works, concrete goods and metal structures delivery), thus ensuring 100% level of Kazakhstan content of works.

Total value of the Project is 43.6 bln. tenge. With the view of financing, KEGOC JSC concluded loan agreements with international and domestic financial institutes (IBRD, EBRD, DBK).

Total length of 500 kV transmission lines of the second “Kazakhstan North-South” transit will make 1096 km. In October 2008, 500 kV Shu SS and 500 kV OHTL YuKGRES-Shu, 248 kilometers (1st Phase), were energized. Completion of 500 kV OHTL Ekibastuz-Agadyr section, 462 kilometers, is planned for the 4th quarter 2009.
