Greece’s electricity grid is facing a serious stress test due to the ongoing heatwave, with soaring temperatures pushing demand to peak levels. Despite the increased pressure, the Hellenic Electricity Distribution Network Operator (HEDNO) has assured the public that there will be no scheduled power outages, confirming that all maintenance operations on the Distribution Network have been temporarily suspended.
On Monday, July 8, electricity demand is expected to hit one of the highest levels so far this summer, prompting all power generation units across the country to remain active and synchronized with the grid.
At the same time, technical teams from HEDNO and the Independent Power Transmission Operator (IPTO) are on high alert, ready to respond swiftly in the event of any system failures.
The situation was assessed during a crisis task force meeting held on Monday, July 7, chaired by Environment and Energy Minister, during which current conditions were evaluated and the necessary steps to prevent widespread blackouts were agreed upon.
HEDNO has emphasized the critical conditions faced by the medium- and low-voltage Distribution Network, citing the extreme weather as a key risk factor. In response, its personnel has been placed on full standby, prepared to intervene immediately should heat-related damage affect any part of the infrastructure.
Power Supply and Energy Mix
According to IPTO, Greece’s high-voltage Transmission System Operator, electricity demand is expected to peak at approximately 9,700 MW during the early afternoon hours of July 8. To meet this demand, the country will rely on a diverse energy mix:
• Natural gas: 44.95%
• Renewables (RES): 39.77%
• Large hydropower plants: 4.67%
• Lignite units: 3.71%
• Electricity imports: 3.66%
