Currently, design and estimate documentation has been developed for 14 overhead lines of 24 and 13 design estimates were approved by project examination authority (GosExpertiza) and 1 design and estimate documentation is under examination. For the remaining 10 overhead lines, the procedure for developing design and estimate documentation is underway.

 For stage 2, the feasibility study for the project of “Rehabilitation of 220-500 kV OHTLs in Akmolinskiye MES, Vostochnye MES, and Severnye MES branches’ is in progress and planned for completion in 2021. A contract for development of the feasibility study was concluded with RBM Sweko Producktions LLP on 18 July 2019.

The for stage 3 of the project for "Rehabilitation of 220-500 kV OHTLs in Al-matinskiye MES, Tsentralnye MES, and Yuzhnye MES branches "is planned for completion in 2023.
