June the 28th, 2026 – The ongoing heatwave is pushing electricity consumption across Croatia to record levels as people keep their air conditioners on day and night in order to cope. Is a blackout possible as a result?
As Poslovni reports, Croatia’s ongoing heatwave is putting pressure on the country’s electricity system as rising temperatures drive increased use of air conditioning. Electricity demand is constantly and significantly climbing, with evening consumption expected to approach record levels as households, tourists and businesses desperately try to cool down.
According to estimates from the Croatian Transmission System Operator (HOPS), evening consumption could exceed 3,000 megawatts. The current record hourly consumption was recorded back in July 2024, when demand reached around 3,363 megawatts.
Energy experts say the system remains stable, but this summer could bring new records. Consumption is being pushed higher not only by households, but also by tourism and industry. The peak season has not yet reached its full intensity, meaning hotels, apartments and electric vehicle charging could add further pressure in the coming weeks.
The question many are asking is whether Croatia could face a blackout. Experts say a complete collapse of the system is always possible in theory, but it is not currently expected. Croatia is connected to the wider European electricity network, allowing energy flows to be balanced across borders when needed.
Solar power is helping, especially during the day when production from rooftop solar systems rises. However, experts warn that solar energy also creates challenges for grid management because the transmission system must balance fluctuating production and demand.
Recent investments are aimed at strengthening the grid. The Croatian government allocated €114 million for improvements to the transmission network, including new infrastructure and additional capacity for renewable energy sources. Future “smart grid” systems are expected to manage electricity flows more efficiently in real time.
For now, Croatia’s power system is under strain, but not in genuine crisis. The real test of that will come as the hottest part of summer and the peak tourist season arrive. It’s easy to forget with these insufferable temperatures that we’re not even there yet.
