Rehabilitation of 220–500 kV OHL branches in Akmolinskiye MES branch, Vostochnye MES branch, Severnye MES branch and Tsentralnye MES branch of KEGOC, Stage II

Project goal: Improve the reliability of the NPG of Kazakhstan through the rehabilitation of the existing power lines that have surpassed the standard service life limit including the lines that will do so in the coming years.

Project implementation period: 2019 - 2031

Project cost: KZT 94.64 billion inclusive of VAT

Project funding: 65% of borrowed funds, 35% of the company funds.

Place of implementation: territory of the Republic of Kazakhstan.

Project description: Need for rehabilitation of the UPS due to:

·     some 220-500 kV overhead lines that have reached or exceeded the standard service life limit.

·     reliability of power supply to consumers, the transmission of electricity, evacuation of power from power plants that will be enhanced as a result of this project.

The targets of rehabilitation are 48 overhead lines of 220-500 kV of KEGOC with a total length of over 4236 km on the balance sheets of Akmolinskiye MES branch, Vostochnye MES branch, Severnye MES branch, and Tsentralnye MES branch of KEGOC.

Current status: On 18 July 2019, KEGOC signed a contract with RBM Sweсo Productions LLP for the development of a feasibility study for Rehabilitation of 220–500 kV OHL branches in Akmolinskiye MES branch, Vostochnye MES branch, Severnye MES branch and Tsentralnye MES branch of KEGOC, Stage II.

Examination of 48 overhead lines has been completed. 48 technical OHTL survey reports have been submitted and approved.

The contractor continues to develop a feasibility study (FS) report.

Planned completion: June 2024. Cause: Due to the unavailability of sections of the feasibility study for delivery.

Rehabilitation of 220–500 kV OHL branches in Almatinskiye MES branch, Tsentralnye MES branch, and Yuzhnye MES branch of KEGOC, Stage III

Project goal: Improve reliability of the NPG of Kazakhstan through the rehabilitation of the existing power lines to extend the service life by at least 30 years.

Project implementation period: 2021-2031

Project cost: KZT 96.62 billion inclusive of VAT

Project funding: 70% of borrowed funds, 30% of the company funds.

Place of implementation: Kazakhstan.

Project description: Need for rehabilitation of the UPS due to:

•    some 220-500 kV overhead lines that have reached or exceeded the standard service life limit.

•    reliability of power supply to consumers, the transmission of electricity, evacuation of power from power plants that will be enhanced as a result of this project.

The rehabilitation covers 44 OHTL of 220-500 kV, located in Almatinskiye MES (12 lines of 220 kV), Tsentralnye MES (13 lines of 220-500 kV) and Yuzhnye MES (19 line of 220-500 kV) with the total length of 4332 km.

Current status: The KEGOC Management Board approved moving the project to the "Selection" stage for the production of a feasibility study report (minutes No.4 dated 12 February 2021). The Board of Directors of KEGOC approved the preliminary parameters and made a decision to support the above decision of the Management Board (minutes No.3 dated 19 March 2021).

A contract was signed with KazSelEenergoProekt Institute LLP No. 540230/2021/1 dated July 14, 2021 for development of a feasibility study report for rehabilitation of 220–500 kV OHL branches in Almatinskiye MES branch, Tsentralnye MES branch, and Yuzhnye MES branch of KEGOC.

Examination of 44 overhead lines has been completed. All technical reports based on the results of the technical inspection of overhead lines have been submitted for approval. These include:

- 26 technical OHTL survey reports that have been submitted and approved.

- 18 technical OHTL survey reports have been submitted for approval to MES branches.

The planned completion date is June 2024. The reason is due to the unavailability of sections of the feasibility study for delivery.

West Kazakhstan Power System Interconnection Project. Construction of power grid facilities.

Project goal: Interconnect Zone West with the main part of the UPS of Kazakhstan over Kazakhstan inland territory to ensure energy security and energy independence of the Western regions of Kazakhstan, improve the reliability of power supply to consumers in Zone West.

Grounds: The project was launched in accordance with clause 2.41.1 of the Roadmap and the Action Plan for the implementation of instructions given by the President of the Republic of Kazakhstan at the expanded meeting of the Government of the Republic of Kazakhstan on January 26, 2021 (to devise a plan to strengthen interconnection between Kazakhstan's western regions and connect them to the Kazakhstan Unified Power System) and paragraph 56 of the Action Plan for the implementation of the election programme of the President of the Republic of Kazakhstan “Fair Kazakhstan for everyone. Now and forever” to complete construction of a power transmission line that loops the country's energy system.

Project implementation period: 2023-2027

Project cost: KZT 201.79 billion including VAT (including costs for commissioning, historical and cultural examination, etc.)

Project financing: 30% of equity funds, 70% of borrowed funds

Project description: The project will connect Zone West with the rest of Kazakhstan's UPS over the inland territory, ensure energy security and independence of the western regions of Kazakhstan, improve the dependability of the Zone West power supply to consumers, and use local flexible generation to make up for imbalances in electricity and power in Zone North and Zone South.

Current status: In 2022, the preliminary feasibility study for the project was completed, the technical and economic feasibility of interconnection of the power system of Western Kazakhstan with the UPS of Kazakhstan was confirmed.

Based on the findings of the first stage of the feasibility study, KEGOC has chosen an option that calls for the construction of 500 kV overhead line from Karabatan substation to Ulke substation.

The feasibility study (FS) report for the project has been developed and GosExpertiza’s report has been issued (No. 01-0047/24 dated 12 February 2024).

According to corporate procedures, a decision on further implementation of the project and transition to the next stage is expected.
