Kyrgyzstan explains Toktogul HPP generator shutdown amid regional power fluctuations

Kyrgyzstan's Ministry of Energy has explained the reasons behind a technological malfunction that temporarily shut down two generators at the Toktogul Hydroelectric Power Plant on August 14th. The incident caused a brief disruption within the Central Asian unified energy system, leading to frequency fluctuations.

At the same time, the energy system of Kyrgyzstan provided assistance to neighboring countries by supplying capacity in the amount of approximately 250 MW.

According to the ministry, rapid measures were taken to stabilize the energy system, restoring the frequency to a normal 50 Hz by 3:55 PM. During this period, Kyrgyzstan provided approximately 250 MW of power capacity to neighboring countries. The ministry stated that the initial disruption occurred within the unified energy system of Central Asia, leading to changes in power flows and the activation of emergency protection systems.

However, the ministry emphasized that this initial disruption cannot be directly equated with the subsequent power outages experienced in other countries. It noted that energy systems are designed to maintain stable operation, even in isolated modes with reduced frequency, until balance is restored. Therefore, a separate analysis is required for the subsequent events in the power systems of other Central Asian nations.

This was the initial disruption in the parallel operating unified energy system of Central Asia, which led to changes in power flows and the operation of emergency protection.

A special commission has been formed to investigate the precise causes of the technological malfunction. The Ministry of Energy stressed that it would be incorrect to assign responsibility for all subsequent consequences of the accident to Kyrgyzstan's energy system before the joint technical investigation is completed.

It is incorrect to attribute responsibility for all subsequent consequences of the accident to the energy system of Kyrgyzstan until the joint technical investigation is completed.
