Recently, the media have published various materials on the situation in the power system of Kazakhstan, including those containing incorrect information.
In this connection the System Operator of the Unified Power System of Kazakhstan KEGOC reports the following.
On 10 November 2021, at peaking evening hours, the consumption in Kazakhstan amounted to 14,838 MW, and generation was 14,265 MW.
The capacity deficit of 573 MW was covered by cross-border power flows from the power system of Russia. Of which 10 MW were electricity supplies to Kazakh consumers and 563 MW were intersystem flows to compensate the unscheduled deviations of consumers in Kazakhstan.
For reference: Since the beginning of the year, the coal-fired power plants have generated 66.9 billion kWh of electricity or 69% of the total generation. The gas power plants generated 18.9 billion kWh or 19.5% of electric power, hydro power plants 7.4 billion kWh or 8% of electric power, and renewable power plants 3.6 billion kWh (about 3.5%).
500 MW power units No.2 and No.7 at Ekibastuz GRES-2 after 12,304 hours and 25,968 hours of operation without maintenance respectively (the standard rate is 6,570 hours per year) have been shut down for regular maintenance. The planned maintenance completion date is 27 November 2021 for unit No.2 and 11 November 2021 for unit No.7. At EEC JSC power plant, unit No.4 also has been shut down for regular maintenance of the turbine and one boiler, which is expected to be completed on 12 November 2021.
Once the above generating equipment is engaged after maintenance it will significantly increase the generation capacity to meet the demand of consumers in Kazakhstan.
300 MW Moinak hydro power plant will be re-engaged on 8 November 2021, after accumulation of sufficient water levels.
The total capacity of emergency maintenance shutdowns, including regional CHP plants, is 1,150 MW.
As for load shedding cases in the regions since the beginning of November this year, they were caused by non-contractual consumption of consumers and energy supplying organizations located in the networks of regional power grid companies, such as ShygysEnergoTrade LLP, SevKazEnergo JSC, AstanaEnergoSbyt LLP, EnergoPotok LLP, etc. This situation is caused by untimely purchase of electricity by consumers and energy supplying organisations from the country's power plants, including Zhambyl TPP, which has a significant generation reserve.
To limit the non-contracted power flows, systematic actions are taken jointly with the Government of the Republic of Kazakhstan, including the provision of fuel and engaging on additional units at Zhambyl TPP. As of November 11, an additional 200 MW unit at Zhambyl TPP was put into operation. Currently there are 3 units in operation at Zhambyl GRES.
Work has been carried out to organise bidding for imported electricity from Russia to supply electricity to consumers. Work continues with the Government to provide conditions for participation of Kazakhstan power supply organizations in bidding for imported electricity from Russia.
The digital mining farms that comply with legal requirements must carry out their operations without compromising the country's energy security and purchase not only domestic, but also imported electricity.
To identify "grey" digital miners, it is necessary to improve the regulatory framework to establish requirements for entities engaged in digital mining,
According to our estimates, the total consumption capacity is about 600 MW for the registered miners, and 300-400 MW for grey miners.
The coming autumn-winter peak load is expected to be 17,000 MW vs domestic generation of 16,540 MW. The generation deficit of 540 MW will be covered by the flows from Russia, including imports.
KEGOC as the System Operator of the UPS of Kazakhstan keeps the situation under full control and continues to ensure the necessary level of reliability of the UPS of the Republic of Kazakhstan.
