Kazakhstan's State Commission, chaired by First Deputy Prime Minister Nurlanbek Nalibayev, reviewed measures to strengthen the national power grid after a technological failure on August 14, 2026, isolated the southern zone. The commission focused on improving emergency automation, inter-system links, and flexible generation, including Almaty CHP-2 and CHP-3. The August incident cut three 500 kV lines and led to about 2,810 MW of supply restrictions.

Key Facts

The State Commission, chaired by First Deputy Prime Minister Nurlanbek Nalibayev, reviewed measures to strengthen the power grid after the August 14, 2026 failure.
Almaty CHP-2, CHP-3, and the Turkestan combined-cycle plant were named among key facilities for flexible generation.
The August 14 incident disconnected three 500 kV transmission lines and isolated the southern zone with the Central Asian power system.
Preliminary operational data from KEGOC estimated supply restrictions at about 2,810 MW.
The commission instructed state bodies and organizations to implement measures developed from the investigation.

Grid Strengthening Measures

The State Commission, chaired by First Deputy Prime Minister Nurlanbek Nalibayev, reviewed measures to strengthen the national power grid. The commission heard reports from the Ministry of Energy and KEGOC on the progress of the investigation. Discussions focused on improving emergency automation, inter-system links, and flexible generation. State bodies and energy companies were tasked with enhancing reliability of power supply and developing connections with neighboring power systems.

Flexible Generation Focus

The commission placed special emphasis on flexible generation, naming Almaty CHP-2, CHP-3, and the Turkestan combined-cycle plant among key facilities. Flexible generation allows the power system to quickly adjust electricity production when consumption or cross-border flows change sharply. This issue is particularly sensitive for southern regions after the technological failure that affected the country's unified power system.

August 14 Incident

On August 14, 2026, a technological failure in Kazakhstan's unified power system disconnected three 500 kV transmission lines. The southern zone of Kazakhstan, together with the Central Asian unified power system, switched to isolated operation. Preliminary operational data from KEGOC estimated supply restrictions at about 2,810 MW. The operator later restored the power system scheme and synchronized the southern zone with the main part of Kazakhstan's unified power system. The commission is still establishing the final causes of the failure; preliminary assessments published immediately after the accident are not final investigation results.
