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 2019, KPO has been supplying 36 to 43 MW of electrical power to the regional network. In 2019, the total electricity supply was 330.26 mln KWh. The supplies of electrical power and fuel by KPO in the period of 2017-2019 are presented in table below.

In 2019, the volume of electricity for the WKO increased and reached 330.26 million kWh, which is 8% higher (25.2 million kWh) than in 2018.
The increase was achieved due to planned repairs of turbines and generators in a shorter timeframe, as well as due to the postponement of the overhaul of GTG № 3 for the period of full-scale shutdown. This allowed all four generators to generate electricity in the spring without reducing the supply of electricity to the region.

Since the volume of electricity production for «Aksaienergo» LLP in 2019 amounted to 26.28 million kWh at the rate of 3 MW, for «Batys energoresursy» LLP, electricity production increased by the above 25.2 million kWh.

In 2019, electricity generation was mainly produced using own gas produced at the KPC plant. Purchases of gas from a third-party supplier for the production of electric energy for the needs of the region amounted to about 20.5% of the total gas consumption at the GTPP and were carried out mainly during the shutdown, when KPO’s own gas was not produced.

In the reporting year, Company did not experience any production losses due to the influence of external power grids or problems with turbines.
