Kazakhstan's power grid had no reserves during the winter peak, with consumption reaching 17,724 MW against generation of 16,684 MW on December 18. The southern transit corridor is nearly fully loaded at about 2,300 MW, while data centers and AI projects have already requested around 1 GW. The government promises to end the power deficit by 2027, even as demand is projected to reach 22.8 GW by 2030.

Key Facts

Kazakhstan's electricity consumption rose 9.4% over five years to 124.6 billion kWh in 2025, while production grew 7.6% to 123.1 billion kWh.
On December 18 at 17:55, peak demand hit 17,724 MW against generation of 16,684 MW, with the deficit covered by imports.
KEGOC projects maximum load to reach 22.8 GW by 2030 and 25.3 GW by 2032, with a surplus of about 6.2 GW expected by 2035 if planned plants are built on time.
The southern zone's own power plants cover about half of its consumption, with the rest supplied via the North–East–South transit corridor, which has a maximum capacity of about 2,300 MW and is nearly fully loaded.
On August 14, a major disturbance in the Central Asian unified power system began in Kyrgyzstan when two Toktogul HPP hydro generators totaling 625 MW tripped, causing Kazakhstan's power system to absorb the deficit and triggering automatic load shedding.

Winter Peak Strain

Kazakhstan's electricity consumption grew 9.4% over five years, reaching 124.6 billion kWh in 2025, while production rose 7.6% to 123.1 billion kWh. In the first eight months of 2026, consumption reached 83.6 billion kWh, up 2% year-on-year, while generation rose 1.7% to 82.5 billion kWh. The last winter peak was recorded on December 18 at 17:55, when demand hit 17,724 MW against generation of 16,684 MW. KEGOC reported that no reserves were available and the deficit was covered by electricity imports from neighboring power systems. KEGOC forecasts maximum load to reach approximately 22.8 GW by 2030 and 25.3 GW by 2032, with a surplus of about 6.2 GW expected by 2035 if planned power plants are commissioned on schedule.

Southern Zone Deficit

The southern zone's own power plants cover about half of its consumption, with the remainder supplied via the North–East–South transit corridor. The corridor's maximum transmission capacity is about 2,300 MW, and KEGOC says it is now almost fully loaded. KEGOC is building new 500 kV transmission lines to reinforce the grid. Data centers and AI projects have already declared a need for roughly 1 GW of capacity.

August 14 System Disturbance

On August 14, a major disturbance in the Central Asian unified power system began in Kyrgyzstan when two hydro generators at Toktogul HPP, totaling 625 MW, tripped. The resulting deficit was initially covered by Kazakhstan's power system, but the power surge exceeded the permissible 300 MW. This disrupted the stability of the North–South and East–South transit corridors, and automatic protection systems disconnected lines and some consumers. A commission with representatives from Kazakhstan, Kyrgyzstan, Uzbekistan, and Tajikistan is investigating the causes of the accident.
