Energy supply to Western Kazakhstan

KPO generates and supplies electrical power to the West Kazakhstan Oblast in addition to the own primary needs to maintain operations in the Karachaganak Field. This is implemented in accordance with the terms of the Karachaganak Final Production Sharing Agreement (Art.I Section 1.1) providing for sale to Aksai and surrounding villages no less than 20 MW power generated at the KPC Gas Turbine Power Plant. The implementation mechanism of this obligation was set in the Joint Operating Committee’s Resolution of March 2005.

Four generators are installed and operated at the KPO Gas Turbine Power Plant (GTPP), whilst three generators are dual-fuelled.

Power generated at the KPO GTPP is transmitted to the own units throughout the Field, which include KPC, Unit-2, Unit-3, Gathering system, Eco Centre, Pilot Camp, Bolshoi Chagan pumping station and block valve stations 1-26. The power is also transmitted to the two energy supply organisations: Batys Energoresursy LLP and Aksaienergo LLP. These organisations supply electrical power to the final consumers in the WKO.

During the 2018, KPO has supplied 40-45 MW of electrical power to the regional network. The supplies of electrical power and fuel by KPO in the period of 2016-2018 are presented in table below.

In 2018, the volume of electric power supplied to the WKO has slightly decreased (less than 1%) compared to the 2017 because of increased scope of maintenance works at the GTPP turbines and generators.

At the same time, in order to maintain high-level electricity production for the region, for the first time in KPO practice, there were two different types of major concurrent repairs of the turbine and generator. Due to the two-shift work arrangement, the total repair duration was reduced from 60 to 44 days. This made it possible to carry out the early launch of Turbine No. 2 and keep the electricity production for WKO as close as possible to the previous year levels.

It should be noted that the volume of electricity supplied for Batys Energoresursy LLP in 2018 was slightly higher than in 2017.

In 2018, in addition to the above overhauls of Turbine No. 2 and Generator No. 2, there were an inspection (repair) of the hot gas section of Turbine No. 4 as well as small inspections of generators No. 2 and No. 4.

In 2018, electricity was generated mainly using our own gas, produced at the KPC plant. Gas purchases from a third-party supplier for the electricity production for the region needs amounted to less than 7% of the total gas consumption at the GTPP.

In 2018, KPO did not experience production losses due to the influence of external power grids.
