Key Facts
- —What is happening The national utility says it suspects deliberate interference tripped a key power line at about 8:12 a.m.
- —Why it matters Guyana’s fast-growing oil economy needs a stable grid; an attack on power lines would be a security risk.
- —The numbers Line L2 tripped on an earth fault; the utility says it inspected the line the day before and found it clear.
- —Who is who Guyana Power and Light (GPL) runs the national grid; L2 and L4 are parallel high-voltage lines.
- —What to watch Whether police confirm sabotage or make an arrest; no police statement was found by Monday, 2 November.
- —What it means for you Plan for outages and keep backup power; no change to US travel advice or oil output is confirmed.
Guyana’s national power utility says it strongly suspects someone deliberately interfered with a high-voltage line that caused a widespread blackout. It calls this a suspicion, and no police statement has been found.
Guyana Power and Light (GPL), the national electricity company, says it strongly suspects sabotage caused the latest widespread blackout. Its statement, published on Friday, 30 October, says the L2 transmission line tripped at about 8:12 in the morning.
The blackout matters to US readers because Guyana’s offshore oil boom brings American firms, workers and visitors who rely on the grid. A deliberate attack on power lines would be a new risk for that economy.
What GPL Says Happened
GPL says the L2 line tripped on an earth fault. The line runs parallel to the L4 line between the Grove and Sophia substations.
The fault was on the C-phase conductor, the lowest of the three. GPL says it inspected the L2 line on Thursday, 29 October, and found no faults or vegetation.
After the trip, GPL says, its teams again found no fault, no vegetation and no physical condition that could explain it. It says its technical teams worked to restore supply.
GPL says it strongly suspects deliberate interference with critical infrastructure, and stresses that this is its suspicion. It says it is investigating and will pass any evidence of unlawful activity to the authorities.
GPL says it is increasing surveillance and protection of its transmission assets. It asks the public to report suspicious activity near lines, towers or substations to GPL or the nearest police station.
In Plain English
A transmission line carries high-voltage power from power stations to local networks. When one trips, protection equipment switches it off to avoid damage.
An earth fault means current leaked to the ground, for example when a line touches a tree or tool. GPL says it found no such cause on the L2 line.
Suspicion Is Not Proof
GPL’s suspicion rests on the absence of any physical cause found after the trip. That is not proof of sabotage, and only an investigation or a court can establish it.
No police statement and no arrest linked to the blackout have been found. GPL has not published evidence of deliberate interference.
What It Means for You
Visitors and businesses in Guyana should plan for outages, with backup power for key equipment. GPL asks everyone to report suspicious activity near its lines.
No change in US travel advice or in oil output has been confirmed. Check the US State Department advisory for Guyana before any trip.

What Is Not Known
The statement names no affected areas and gives no restoration time. It is unclear how long the outage lasted or how many customers lost power.
GPL calls this the latest widespread blackout but gives no details of earlier ones. It is not known whether they had the same cause.
