On 14 October 2021, large power units with a capacity of 500 MW failed with an interval of several hours at Ekibastuz GRES-1 and Ekibastuz GRES-2. A boiler was emergency shutdown with a decrease in generation by 150 MW at the power plant of EEC.

Thus, the total volume of emergency reduction of generation at the above three power plants exceeded 1000 MW.

In the conditions of the existing power shortage, these emergency shutdowns at power plants will lead to unacceptable deviations in power at the border with the Russian power system, with overloading of interstate power transmission lines with the threat of a systemic accident.

To prevent an accident and minimize the consequences of a decrease in generation in the power system, KEGOC, in coordination with the Ministry of Energy of the Republic of Kazakhstan, together with regional power grid companies, limited the consumption of electricity by consumers carrying out excess consumption. The restrictions were introduced according to the schedules agreed with the local executive bodies.
