Power supply

For production needs within the Karachaganak field, KPO generates electrical power at its own Gas Turbine Power Plant (further as GTPP). Generated power is transmitted to the own production units: KPC, Unit 2, Unit 3, Gathering, Eco Centre, Pilot Camp, IT&T Data Centre in Aksai, Karachaganak – Atyrau transportation system covering the oil pumping station in Bolshoi Chagan and block valve stations 1-26.

Four turbines, three of which are dual-fuelled, are installed and operating at the KPO Gas Turbine Power Plant.

In 2023, annual boroscopic inspections of turbines were carried out at the GTPP to diagnose the internal condition of the turbine sections, as well as combustion inspections and chamber replacement at turbine No. 2 and turbine No. 3 in March and April, including turbine No. 1 repair from November to December. The works were performed without delays, within the schedule and in good quality. Materials and spare parts were provided in a timely manner.

Power supply to the West Kazakhstan Oblast

As part of the Karachaganak Field Final Production Sharing Agreement (Art.I, Section 1.1.), KPO generates and exports power to the West Kazakhstan Oblast. In average, the capacity to satisfy the needs of the West Kazakhstan Oblast communities is circa 25 MW in winter and circa 20 MW in summer.

KPO has been exporting power to power supply organizations, such as Batys Energoresursy LLP and Aksaienergo LLP till 30 November 2023 (Aksaienergo LLP closed from 1st December 2023), which in their turn have been supplying the power to the communities and other end consumers in the West Kazakhstan Oblast.

In the course of 2023, KPO has exported from 20 to 35 MW to the regional grid, while the total volume of power export to WKO was equal to ~ 226.8 mln kWh. Decrease of the power export in comparison with 2022 was due to the planned preventive maintenance in 2023, within timeframes not exceeding 15 days, and Turnaround at the Field’s facilities. The terms and scope of planned preventive maintenance are regulated by the operating hours of the main GTPP equipment.

Supply of power and fuel gas in 2021–2023 is listed in Table 55.

Tab. 55.KPO’s supply of power and the fuel gas use, 2021–2023

During 2023, electricity generation was mostly based on KPO’s own gas. Purchases of gas from a third-party supplier for the production of electrical energy for the needs of the region amounted to some 21.2 % of the total volume of gas consumption at the GTPP. In addition to the above period, gas supplies from a third-party supplier were carried out during certain periods of unstable operation of the fuel gas production plant at section 5-339 of the KPC facility.

Power supply system

The local power system at the Karachaganak Oil Gas Condensate Field consists of 110 kV power grids, which, according to lines of responsibility, are owned by three entities represented by KPO, AksaiGasPromenergo JSC and Zapadno-Kazakhstanskaya REK LLP, as well as the KPO 35 kV power lines.

As part of the current initiative aimed to develop measures to reduce accident rate and to increase the stability of the in-field power system in order to substantially minimize production losses due to the influence of the Power grid, a specially organized working group of KPO experts have performed an analysis based on which in 2023 the work with engagement of third parties was carried out to review of the received proposals.

Obligations to support of the use of Renewable Energy Sources

KPO generates power at its own Gas Turbine Power Plant, thus our Company is classified as a contingent consumer in accordance with the Law of the Republic of Kazakhstan on Support of the Use of Renewable Energy Sources (RES).

Contingent consumers are obliged to purchase power generated at the RES facilities in amounts proportional to their share of planned consumption in total power consumption volume of the Republic. As a responsible entity, KPO purchases appropriate scopes of the RES energy from the authorized organization “Financial Settlement Centre on the RES Support” LLP, thereby complying with the legislative requirements aimed at supporting the renewables and contributing to the Green Energy development in Kazakhstan.

In 2023, KPO purchased such energy in the volume of 18,811,317 kWh (equivalent to 67,817 GJ) worth over KZT 675 mln.
