Georgia Endures Third Nationwide Blackout Amid Testing and Leadership Changes
8/6/2026, 10:17:43 AM
Core Event: August 5 Power Failure Across Georgia
On the evening of August 5, electricity collapsed across most of Georgia, including Tbilisi, at roughly 20:10 local time. The outage halted the Tbilisi Metro, disrupted railway services and left millions without power for about an hour before restoration began around 21:00.
Background & Context: Recent Blackouts and Grid Vulnerabilities
The August outage followed a major blackout on July 24-25 that left the country without power for several hours. Preliminary analysis identified a fault on the 110 kV Geguti transmission line from the Kutaisi-220 substation, which contributed to a cascade that disconnected Georgia from Azerbaijan’s grid.
Timeline of Recent Outages and Personnel Moves
- July 24-25 – First of three recent nationwide blackouts; fault on Geguti line reported.
- July 30 – GNERC working group released preliminary findings.
- Early August – State Electrosystem chair Vano Zardiashvili placed on leave.
- August 5 – Third blackout; testing at Enguri hydroelectric plant cited as trigger.
Data & Statistics: Frequency and Scope
- Three nationwide blackouts occurred within two weeks.
- Georgia’s 3.7 million residents experienced loss of electricity each time.
- Critical infrastructure affected included the Metro, railways, water supplies and the grid’s connection to Azerbaijan.
Official Statements & Responses
Giorgi Pangani of GNERC said the August outage coincided with “planned testing” by the State Electrosystem (GSE) at Enguri, which required the system to operate in isolation at non-standard frequencies. GSE confirmed the work was intended to study the July failures and that the temporary isolation caused the blackout. The Economy Ministry noted that Davit Vardiashvili, formerly director of the Georgian Gas Transportation Company, had been transferred to the Electrosystem as deputy chair and was performing the chair’s duties while Zardiashvili remained on leave. The State Security Service opened a parallel investigation into possible sabotage.
Criticism & Opposition
The GNERC working group criticized the state energy system for lacking fully operational high-speed protection on transmission lines and urged recalibration of protection settings. Giorgi Abramishvili, a supervisory board member, dismissed the findings as biased and unrelated to Zardiashvili’s departure.
On-the-Ground Reports
Metro passengers were forced to disembark and walk to stations. Railway operators reported interruptions on several routes, and social-media posts described darkness throughout residential areas. Water supplies in multiple regions were also temporarily disrupted.
Conflicting Reports & Gaps
Russian news agencies attributed the blackout to testing at a major hydroelectric plant, while Georgian officials linked it specifically to Enguri in the occupied Abkhazia region. No comprehensive official statement explaining the precise trigger has been issued.
What’s Next: Ongoing Investigations
GNERC indicated further examination is required on the grid’s ability to operate in isolated mode and on the disconnection from Azerbaijan. The sabotage probe remains active, and the Economy Ministry has not clarified the timeline for a permanent appointment to the Electrosystem chairmanship. Monitoring of the grid’s protection systems is expected as authorities seek to prevent additional nationwide outages.
