The European Network of Transmission System Operators /ENTSO-E/ is investigating the incident that occurred yesterday in a part of the electricity supply system in South-Eastern Europe, it was announced today on the website of “ENTSO-E”.
The announcement states that the incident took place in Albania, Montenegro, BiH and partially in Croatia.
“Threatened operators of network systems, with the support of neighboring operators, established a normal flow of voltage after almost two hours with the aim of reducing the impact of the problem on consumers,” the announcement states.
“ENTSO-E” is currently working to collect technical data about the incident from the affected operators and will publish additional information as soon as possible.
In accordance with the incident classification methodology, the System Operations Committee will conduct a detailed investigation of the incident in the coming weeks, with the support of an expert team.
Several cities in Bosnia and Herzegovina, Montenegro, Croatia and Albania were left without electricity yesterday due to problems in the transmission network in the region and overloading of key interconnecting lines.
In Bosnia and Herzegovina, there was a complete collapse of the electric power system on June 21st.
The Independent System Operator in Bosnia and Herzegovina NOS is responsible for the transmission of electricity in Bosnia and Herzegovina.
Klix.ba was told by Elektroprivreda BiH that the reason for the interruption of the electricity supply was an outage on the transmission lines in the region and the transmission of disturbances to the BiH system.
As HINA reports from the Croatian transmission system operator, everything started from Montenegro, then the power outage affected Bosnia and Herzegovina, and then Croatia. Such an interruption has never happened before through these three states.
Dispatchers between states are currently communicating to come up with a recovery plan because no state can be isolated in terms of power supply because they are all connected by transmission lines.
It is not clear what the exact cause is, but it is assumed that due to high temperatures, consumption jumped and the system collapsed.
“We still don’t know the cause, but the entire power system went out. We are doing everything to keep the facilities at the Tuzla Thermal Power Plant safe,” Fuad Muminović, director of the Tuzla Thermal Power Plant, told Klix.ba earlier.
At 12:35 p.m., there was a complete interruption of the electricity supply in the entire state.
