Greece’s electricity system is being pushed to its limits as a seasonal heatwave continues to scorch the east Mediterranean country for a second day, prompting heightened operational readiness from power transmission and distribution operators.

As temperatures soar, the Independent Power Transmission Operator (IPTO) and the Hellenic Electricity Distribution Network Operator (HEDNO) remain on high alert, working to ensure stability amid unprecedented demand.

Power Consumption Hits New Highs

According to IPTO, July 22 marks the beginning of a period of historic electricity consumption, with demand peaking between 12:00 pm and 1:30 pm. During this time frame the system is expected to reach 10,080 megawatts (MW)— the highest levels recorded so far this summer.

Projections for Wednesday indicate even greater strain, as temperatures are forecast to rise further; with electricity demand expected to surpass 10,000 MW once again, reaching a staggering 10,410 MW during peak hours.

Grid Faces Critical Test

The intense heat is driving an extraordinary increase in air conditioner use, placing extreme pressure on both the ultra-high and high voltage transmission networks, as well as the medium and low voltage distribution grids.

Despite the challenging conditions, IPTO officials are expressing confidence in the resilience of the infrastructure, particularly in the ultra-high and high voltage segments. They also affirm the system’s current capacity is sufficient to meet the heightened demand.

Authorities emphasize that while the networks are undergoing a severe stress test, the possibility of a widespread blackout remains distant. For now, the grid is successfully meeting consumption needs, even under these exceptional circumstances.
