Many parts of the world have recently experienced high temperatures and scorching heat. In the Balkans, the heatwave is still ongoing, with temperatures exceeding 40 degrees Celsius visible everywhere. Affected by the high temperature weather, multiple countries experienced power supply problems and widespread power outages on June 21st.
Extreme high temperatures have occurred in many parts of the Balkan region this week, with temperatures exceeding 40 degrees Celsius in many areas. Relevant departments of various countries have issued high temperature warnings, reminding people to prevent heatstroke and cool down.
Due to historical reasons, the power grids of multiple countries in the Balkans are interconnected. The Montenegrin government announced on the 21st that the country's power distribution system experienced power supply problems for several hours that day, and large-scale power outages also affected countries such as Croatia, Bosnia and Herzegovina, and Albania. Affected by power outages, there were varying degrees of traffic paralysis on the 21st in cities such as Sarajevo, the capital of Bosnia and Herzegovina, and Split, a coastal city in Croatia. The traffic lights on the street have stopped operating, and the tram has also been shut down due to a lack of power.
The specific reason for this power outage is not yet fully understood. The State Electricity Company of Bosnia and Herzegovina stated that the power outage was caused by issues with the regional distribution lines; The Albanian State Power Company has explicitly stated that the "extreme heat" caused the widespread power outage. Industry insiders suggest that the surge in electricity demand in various countries due to the impact of high temperatures, leading to the collapse of the power grid, is a more likely cause of this large-scale power outage.
Danko Blajevic, Director of Operations of the Croatian Transmission System: I don't want to jump to conclusions, but preliminary information shows that the power grid between Greece and Albania is starting to collapse, and then the lines have changed. But this is still speculation and unverified information.
Minister of Energy and Mining of Montenegro, Sasha Muyovic: The problem is partly due to a significant increase in daily load, and partly due to very high temperatures. When these two factors are combined, there will be a situation where power cannot be supplied normally, that is, the line will be overloaded and cause faults.
