HISTORY OF JSC "MANGISTAU DISTRIBUTION ELECTRIC GRID COMPANY"
In 1962, with the creation of the Ministry of Energy of the Kazakh SSR, the merging of power plants and individual energy centers into large energy systems began, which were almost completed by the beginning of 1971. Since that time, the rapid growth of the energy base of the republic began, the determining factor of which was the transition to the sectoral management system.
Subsequently, with the rapid development of oil production in Mangyshlak in the 60s, its own energy base began to be created.
For a long time, the region’s power industry developed autonomously and the only source of generating power here was the Mangyshlak Nuclear Power Plant, which worked in isolation, having practically no interconnection with other stations.
And only commissioning in 1988 of the 220 kV Aktau-Beyneu-Tengiz inter-system power line allowed the Mangyshlak Nuclear Power Plant to work in parallel with the entire power system of the republic.
Mangyshlak power networks Enterprise was founded in 1966 as part of Kazakhstanneft.
In 19.03.1967 Mangyshlak power networks Enterprise as part of the Industrial Association "Mangyshlakneft" was transferred to the structure of the regional management of the energy economy "Gurevenergo".
Over the years of the enterprise’s existence, the work collective has done a truly invaluable work on the continuous electrification of our region. Today on the map of the region there is practically no settlement where the electrical networks would not be laid.
During the existence of the Mangyshlak Electric Networks Enterprise, a great deal of work was done on the commissioning of new networks, on increasing the level of operation and reliability of networks.
The first 110/35/6kV Uzen substation was built and commissioned in 1965 (now it is Gorodskaya substation), the second substation was commissioned in 1966 in the settlement of Zhetybay.
