Also in 2021, design and estimate documentation was developed for all 11 facilities (6 substations and 5 overhead lines), positive opinions were received from the examination authority for the design and estimate documentation, and construction and installation work began.

In 2023, construction and installation work was completed on all five sections of the 220 kV overhead line “Uralskaya-Pravoberezhnaya”, “Pravoberezhnaya-Inder”, “Inder-Karabatan”, “Karabatan-Kulsary”, “Kulsary-Tengiz”. The commissioning of the 220 kV overhead line "Uralskaya - Pravoberezhnaya - Inder - Karabatan - Kulsary - Tengiz" with a total length of 779.7 km took place on November 28, 2023 with the participation of the Prime Minister of the Republic of Kazakhstan in a teleconference mode. As a result of the inclusion of the second transit chain between the West Kazakhstan and Atyrau regions, the capacity of the electrical network was significantly increased: in the section "West Kazakhstan Energy Hub - Atyrau" from 100 MW to 200 MW; on the Atyrau – Mangistau section from 50 MW to 200 MW. Together, this doubled the reliability of the Western Zone network. The probability of disconnecting consumers is minimized.

Implementation status as of 29.02.2024.
